    Customers like the value and appearance of the headphones. For example, they say it's 100% worth the price and looks much more expensive than it is. Customers are also satisfied with the detail level and sound quality. That said, some complain about the weight. Opinions are mixed on fit, quality and performance.

    Customers like the sound quality of the headphones. They say the bass levels are on par, the vocal track sounded completely natural, and the sound is clear, rich, and spacious. They also mention that the high notes can definitely be enjoyed in genres such as classic, and that it catches high pitch frequencies to low pitch frequencies. Customers also say that the headphones are good at cancelling out background noise, and are the best in-ear headphones on the market.

    Customers are mixed about the quality of the earbuds. Some mention that they are very good in build quality, the sound quality is good, and the cord is strong. However, others say that the loss in quality could be noticed, the EARBUDS completely fell apart after about a year, and have a very short lifespan.

    80 customers mention77 positive3 negative

    Customers are impressed with the clarity and sound quality of the headphones. They say it has clear highs and mids through all volume levels, with no distortion. Customers also say the soundstage is crazy and the mids are perfectly clear. They also say that the mic on them is very clear and the deep notes are definitely there.

    "...But even playing Apple Music at 256kbs, the sound was brighter, more detailed and warmer than any other buds that I have tried in this price bracket...." Read more

    70 customers mention50 positive20 negative

    Customers like the appearance of the headphones. For example, they say the aesthetic is beautiful, thoughtfully designed, and sick.

    Customers are mixed about the fit of the headphones. Some mention that it's super comfy, while others say that it isn't secure in the ear. They also say the bass is swinging, tight, and punchy with no boom. However, some customers feel the carrying case is sturdy and completely too big for a thing like this, and the sound stage is open but not as wide as they'd like. They say the sound quality is excellent, but the fit and sound are not great for wearing for very long periods of time.

    55 customers mention16 positive39 negative

    Customers find the headphones to be heavy due to the metal construction. They say the headphones can feel cold and heavy in the ear, and are too heavy for rubber tips. The remote is also heavy and noticeable when in use. Customers also mention that the bass is slightly heavier on these headphones, but it's by no means thumping. They also say the 1MORE Quads are thin-sounding, tinny, and almost have an underwater sound. Overall, customers find the product to be hard to listen to and ruin the listening experience.

    "...Not one of them will keep these in my ears. They are heavy, great build quality, but heavy. I tried looping the cord over my ears as well...." Read more

    "...The downside of the audio/construction quality is that it makes the buds very heavy...." Read more

    "...So the phone and fax fits very easy in my pocket...." Read more

    Unbelievable price-quality. Best earbuds I've owned (EVER)
    5 Stars
    Unbelievable price-quality. Best earbuds I've owned (EVER)
    I just bought these Quad drivers from 1More based on the quite exceptional reviews (Please Google "1More Quad driver earphones reviews") for these earbuds. At $149 they are right up there in price with the Sennheiser, Beats, Bowers & Wilkins and Bose that lead the market. I had researched the 1More "Triples" and the "Quads" quite thoroughly before going with a brand that I was not familiar with. The "Triples" are, by all accounts, less expensive and just as good in their price bracket and I almost bought them based on PCMags recommendation this year. Since I was not phased at $149 for the Quads I decided to go with their flagship device. So here's the impression after just a day of use.Quality - wow - from the packaging to the look and feel of the components, everything oozes "first class". Think Apple packaging and design. The metal buds are machined to tight tolerances and the dark-bronze metal parts all look and feel like they will last. The whole ensemble is a little weightier than the typical plastic parts you'll find from other well-known brands, but not disturbing once in your ear. The heft makes them feel somehow more worthy and tangibly well-made. These are built to a substantial design and manufacturing quality standard. The right-angle connector for the phone end is also metal and includes a strain relief on the first 1/2" of cable that runs towards the buds. There's nothing plasticky about these except the nice non-sticky cable itself with the metal in-built remote on the right side, and the foam cushions.The earphones arrived in a very high-end looking (and feeling) hard case. Inside the box was an machined metal and logo'd airline adaptor for those twin-pin entertainment ports in armrests as well a a full size 6.3mm amplifier connector (1/4") that snaps cleanly into the standard 3.5mm connector. Also included was a pocket sized hard-shell carrying case for the earphones and an array of small to XL sized silicon and foam rubber cushions to optimize ear seal from 14mm down to 10mm. Although I have quite large ears, I found that the small 10mm foam seals allowed me to secure the L/R ear speakers snugly and with maximum seal. Not having the buds securely placed will leak the bass range out. Having them sit properly provides the precise opposite. Pick your favorite track and be prepared to inhale at any volume. These things can drive. At normal listening volumes thus placed there is little sound leakage. At about 85db, the upper limit for me on earbuds, there is the likelihood of other people's awareness of music leaking out at about 6', but it's faint to the people around me I asked and not disturbing. At more subdued levels, there is little evidence of the music you are playin to the outside world. I will try them in the gym tomorrow but already feel these are secure enough for my routine of cross-trainer and weights.I have only made a couple of calls on them so far, but the sound quality is clean and clear with good sound isolation. The remote hangs up cleanly and when playing music controls volume (but not as I expected fwd/reverse on tracks). On the phone calls I asked if the other party could hear cleanly and without distortion and two reports out of two said the received audio quality was excellent. My end of the line was perfect. So much for the right-side in line mic. No complaint there.Playing music! These plug into my iPhone XS with the official white Apple dongle/DAC to start (the usual "lightning to 3.5mm jack adaptor). Then I played music with two different portable DAC set ups- a Dragonfly Red and my iFi Nano Black before adding the 6.3mm connector to try on my home amp (Peachtree Audio Nova 300 with its own very sophisticated internal DAC). And while it might not be a totally fair comparison to match these 1More earbuds at $149 to my 4x to 5x more expensive headphones (Sennheiser HD700 open back and Oppo-PM-3 planar magnetic closed back), the 1More earbuds stayed with it - I would say effortlessly - across a variety of my favorite listening tracks.I played Talking Heads "Speaking in Tongues" to kick off. Then Muddy Waters "Folk Singer" and Miles Davis "Kind of Blue" all in FLAC/MQA format (hi-res audio files). Frankly, with the Dragonfly Red in line and a high quality source, these earbuds are about the best sounding in-ear speakers I have ever owned. But even playing Apple Music at 256kbs, the sound was brighter, more detailed and warmer than any other buds that I have tried in this price bracket. I have Rebecca Pidgeon's version of "Spanish Harlem" in FLAC and in iTunes and listened to both. Should I confess that the Apple version was pretty darned good and Im not sure I would be able separate it from the hi-res edition in a blind test? Bear in mind, I used an external DAC with my phone to listen to all the tracks. The DragonFly Red does a great job presenting even relatively lo-res files in this set up but even with the Apple Dongle (about $10 from Apple) things were very very good.The bass is an area that won't disappoint. I doubt this is a flat EQ tuned set up, but if you like to feel the pace and punch off a good kick-drum, these bring it on in spades. I'm not a metal fan but listening to some simple old reggae (Burning Spear, "Marcus Garvey" and "Dry & Heavy") bass is swinging, tight and punchy with no boom or muddiness. Voices across the mids stand out with a real sound-stage of their own - even without the BS2B filter I use on headphones (this is an EQ setting within the music app (like Vox) that cleverly meshes the sound output with some fancy filters/algorithms to compensate for overly Left-Right channel separation that is more evident in headphones listening to music mixed by the sound-engineers to play on speakers). This is where the company's bragged about sound-engineer consulting looks like it has paid off. Muddy Waters remastered "Folk Singer" album jumps out, sliding on a 6-string, hand slapping the wood and the singer's breaths and grunts clearly evident with the full range of string vibration spanning highs to lows without any stress. Talking Heads classic remastered album (from 1984 originally, bought then on CD now playing MQA) driving and swinging with synth drum and regular electric bass and David Byrne's crazy vocals as real and cuckoo as we love him to be. Miles' trumpet, even the high notes, never shrill or piercing. Nice roll-off at the upper reaches testifying to an excellent frequency response well beyond my ears all the while letting snare and upright bass occupy their own distinct place in the sound-stage. The overall impression is neither 3D nor plain L-R ...maybe above the head or a little forward...no mean feat when listening to music that may have been recorded on a four track or an eight track.I cannot think of any real downside to these earbuds, especially at this price. For this sound quality in regular headphones you might expect to pay at least twice a much. I've paid much more for much less. So these are going everywhere with me and when I can't be bothered to hook up the big cans will not be subjected to the torture that cheap earbuds inflict on music, especially the 256 kbs variety. These earbuds WILL show up poor quality recordings or lossy files. If that's a beef, stick with lo-resolution cans. (Just joking, who wants that?). If you like detail, taught low-end bass, detailed and warm-forward mids and treble then buy these with confidence. I gave my old Beats (similar price) to my daughter before buying these and have owned the Bose and Sennheiser earbuds prior to these. 1More is the new king. And is not even that close at this price point. I am not a paid reviewer and not connected to the company - or any audio firm - , just a serious music lover with audiophile tastes in equipment - even if I can't afford it. I rarely post reviews of this length and am doing this one because these guys have earned the accolades. Cheap sound is like bad wine. Why bother at all? This is a set of earphones you will enjoy without reservation.

Miles' trumpet, even the high notes, never shrill or piercing. Nice roll-off at the upper reaches testifying to an excellent frequency response well beyond my ears all the while letting snare and upright bass occupy their own distinct place in the sound-stage. The overall impression is neither 3D nor plain L-R ...maybe above the head or a little forward...no mean feat when listening to music that may have been recorded on a four track or an eight track.
    I cannot think of any real downside to these earbuds, especially at this price. For this sound quality in regular headphones you might expect to pay at least twice a much. I've paid much more for much less. So these are going everywhere with me and when I can't be bothered to hook up the big cans will not be subjected to the torture that cheap earbuds inflict on music, especially the 256 kbs variety. These earbuds WILL show up poor quality recordings or lossy files. If that's a beef, stick with lo-resolution cans. (Just joking, who wants that?). If you like detail, taught low-end bass, detailed and warm-forward mids and treble then buy these with confidence. I gave my old Beats (similar price) to my daughter before buying these and have owned the Bose and Sennheiser earbuds prior to these. 1More is the new king. And is not even that close at this price point. I am not a paid reviewer and not connected to the company - or any audio firm - , just a serious music lover with audiophile tastes in equipment - even if I can't afford it. I rarely post reviews of this length and am doing this one because these guys have earned the accolades. Cheap sound is like bad wine. Why bother at all? This is a set of earphones you will enjoy without reservation.

    5.0 out of 5 stars COMPREHENSIVE QuadDriver review (2nd pair)
    Reviewed in the United States on May 31, 2019
    So this is my 2nd pair of quad drivers and I absolutely love it!

    These earphones are robust! They have stellar audio and build quality.

    My first pair left side IEM lost its sound after that 2 storey drop from my balcony.
    (Right side still works)

    I have dropped my old pair for more than I can remember and even dropped these guys in soup. To be honest, these are my go to IEMs when I'm not using my Shure846s(my most coveted IEMs) in my sound room.

    I literally thrash them on-the-go and take them to the gym.

    Looks like the newer pair I just got today has build improvements. I noticed red stoppers on the wires connecting the IEM housings which prevent wiring play compared to my first pairs which had play / "weak spot" of the already durable housing.
    (Newer ones have better durability and most likely would not have this problem)

    My take on the audio:

    Bass and Lows:
    very deep and very well defined bass which is not overpowering/drowns out the highs. They are punchy but not to a point where it causes ear fatigue although you can still enjoy the quad drivers even if you are a bass head. As far as my hearing goes, the box states 20hz lowest but I can attest that these can go lower to 15hz. (More noticeable after the burn-in which takes less than 4 weeks of listening). EDM lovers can enjoy the quad drivers while the acoustic classic rock, and disco listeners will definitely enjoy the fullness of the bass guitar and drums.

    Mids:
    More pronounced with intense background instrumentals in alternative rock and RnB genres / audio recordings having a mid heavy EQ mix tend to drown out the highs and give a "small computer speaker" effect in some occasions. The Mids are generally balanced in classical music but shine in alternative rock.

    In my opinion, if you prefer a more V shaped/bass and high preset like me(despite the V triple BA + dynamic driver config), you can simply solve this issue by just balancing out the mids with a Dolby Atmos EQ enabler (I use android so I use a third party app by Tamil Basak: Xplayer 3D to make them sound close to my Shure846s)

    Highs:
    The highs shine with unparalleled crispness.
    We can only hear up to 20,000hz but knowing that it can reach 40,000hz gives me assurance that you get the "full" listening spectrum and maximize your listening experience(My dog should just have my Quad drivers at this point).
    You get that feeling that you aren't missing out on any high tone sounds.

    Guitar lead solos, high hats, vocals, trumpets, violins and other stringed instruments are very defined and the high notes can definitely be enjoyed in genres such as classic, acoustic, rock, pop and edm.
    Highs are defined but it's overall brightness does not compete with the lows and mids; It complements them.
    Those high vocal notes in your fave songs would send shivers down your spine.

    Sibilance:
    On higher quality 320kbps mp3 files or Flac, I personally don't hear high notes mixing or cutting off.
    Quad driver IEMs Does not cause fatigue to ears at all provided you don't blast the volume.

    The S's from the singers are very gentle on the ears as if they were whispering. (Airy Shhh sounds)

    Soundstage:
    Surprisingly wide, you can definitely tell where all the singers and instruments are placed in the recording room. It is spacious, fine, and accurate.

    Water dripping, tambourine sounds, and alternating arpeggios can be discerned in different areas of the sound stage.

    Noise canceling:
    Does not have NC but upgrading to memory foam tips like Comply or RIYO 12 pair memory foam tips (these tips have better fit and outlast Comply without the price) should insulate yourself from majority of the outside background noise.

    Notes:
    -Be ready to hear Audio Imperfections or poorly mixed audio recordings
    (a plus in my opinion)
    -you are tempted to mess with the EQ a lot if you listen to multiple genres
    -I reduced the gain A LOT which allowed me to increase the intensity of the mids, and highs alongside the bass boost without sacrificing my ears to any added brightness
    -included my EQ preset as a little reference

    Conclusion:

    Overall sound signature is well balanced and these earphones knock out the lows and highs with ease!
    These can take bass boost and treble boost with no problem as I have my bass maxed out and 18% treble boost using a Dolby Atmos EQ enabler.

    These will need DACs to bring out the full potential.

    **EARPHONE CARE**
    DO NOT DROP THESE EARPHONES!
    They significantly lower the life span of the Balanced Armatures and delicate wiring

    DO NOT BRING INTO SAUNAS

    PREVENT LEFT AND RIGHT IEMS from banging into each other (this will increase the life span)

    Hope you find my review helpful!
    Might end up getting a third pair in the future. :)

    5.0 out of 5 stars Soldi ben spesi.
    Reviewed in Italy on November 20, 2023
    Consapevole che è difficile poter dare un giudizio che possa essere significativo per tutti perché come suona una cuffia dipende molto dai gusti e dalla sensibilità di ognuno di noi, ho deciso di approcciarmi ad essa con una prova comparativa delle cuffie in mio possesso. Devo aggiungere che la fonte, la capacità di pilotare le nostre cuffie sarà determinante per la resa delle stesse perché collegarle ad un cellulare o ad un amplificatore non è la stessa cosa. Se vi interessa usarle essenzialmente per telefonare e ascoltare musica senza impegno prendete pure degli auricolari da 30 euro che vi soddisferanno sicuramente. Per ascoltare la musica in maniera coinvolgente allora queste cuffie sono da prendere in seria considerazione. Ad ogni modo ecco le cuffie impiegate nel mio test: Xiaomi Piston 2 (credo), 1more Quad Driver, Shure SE535 e Sennheiser HD565 Ovation. Amplificazione utilizzata Marantz PM17 Signature. Brano dei Radiohead, Burn the witch in flac.
    Il suono delle Xiaomi è terribilmente piatto, suonano perché funzionano ma non trasmettono nulla di che, vanno bene per telefonare e per ascoltare qualcosa in mancanza di altro.
    Il suono delle 1more è straordinariamente molto buono, inaspettatamente godibile. C'è tutto, bassi, medi ed alti nella giusta, a mio avviso, misura.
    Il suono delle Shure è decisamente cristallino ed analitico ma, come dire, più freddo ma stiamo parlando di una cuffia che costa il triplo e che presenta un grave difetto costruttivo: dopo 3 anni di utilizzo normale in casa, senza averle sottoposte ad alcun stress termico, la conchiglia SX si è scollata dividendosi in due. Siccome non sono l'unico ad avere avuto questo problema ciò significa che Shure risparmia sulla colla con il risultato di farmi disaffezionare al marchio e l'acquisto di 1more ne è stato il risultato.
    Il suono delle Sennheiser riprende leggermente in meglio quello delle 1more con un suono più aperto e maggiormente intelleggibile solo perché ho fatto il confronto altrimenti, come equilibrio tonale, avrei detto che suonano alla stessa maniera.
    Quindi secondo me 1more vale tutti i soldi spesi per la qualità sonora che ti viene data, anzi, suonano meglio di cuffie che costano di più. L'affidabilità sarà da verificare ma l'eventualità di ricomprarle per quanto mi riguarda sarà una strada sicuramente percorribile. Da tenere presente anche che il corredo con cui viene fornita la cuffia è veramente sbalorditivo e ti trasmette la sensazione di avere a che fare con un prodotto premium.
    Per uso personale o anche come regalo la 1more Quad Driver è una scelta, per la qualità fornita anche se le colleghi ad un cellulare, decisamente azzeccata. La consiglio.
