The Lypertek Tevi are one of the best true wireless earbuds that I've tried, and I’ve tried a ton of them over the past 2 years. They stack up in terms of sound with my MW07, in terms of call-quality with my Airpods, and in terms of battery life with the PowerBeats (which I tried, but returned). Not to mention they're a fraction of the price of pretty much all of the top end true wireless on the market. I'm going to go into everything in detail, but I can say right off the bat that these are a game changer and rival both true wireless and wired earphones that cost twice or three times as much.Sound Quality:Bass - The bass on these is very good. It extends deep, and has a solid punch, richness, and even some decent rumble. It also never becomes bloated and has great separation from the mids, while adding some nice body to lower range vocals. The bass one of the cleanest I’ve heard on any earbuds. It's not as powerful as something like the PowerBeats, but it's so much better defined, balanced, and detailed.Mids - The mids are fantastic. Both female and male vocals stand out and have clarity, a natural tonality, and are never muffled. Midrange instruments such as guitars, brass instruments, and midrange string instruments sound incredibly realistic and have great resolution. For the past month or so I've been using some fantastic wired earbuds from Final Audio (the E4000), that have some of the best midrange performance that I've heard on earbuds, and these come absurdly close.Highs - The highs are really great. They have excellent, true hi resolution detail and are generally not harsh except a few times in the mid-highs, depending on the song. The highs overall are very slightly pulled back, but still come through with excellent clarity. In my opinion, they have detail retrieval rivaling my MW07, and have slightly better midrange than the MW07.Soundstage - Honestly, this surprised me. These are still true wireless earbuds and as such don't have a super wide stage. The MW07 and Sennheiser Momentum TW (which, once again, I tried but returned bc of bad controls and battery life) are a bit better in this regard. However, the Tevi have an above-average soundstage for true wireless, as well as excellent instrument separation and imaging (location of instruments in the mix).Overall, the sound quality is just incredible for the price. These legitimately sound like they should cost at least twice as much if not more.Look/Fit/Controls: The Tevi have excellent comfort. There are no sharp edges and they fit in my ears really well, which is not always easy for me since I have relatively small ears. They never fell out when I was running and are completely waterproof, so no worries there. They also feel very well made and sturdy, though are very lightweight. They do stick out of the ears a little and can look a bit like earplugs from straight on. But, given everything else these do well this is a compromise I can live with. The controls are also great too, as they provide the ability to operate everything - volume, track skipping, and voice assistant. They have buttons that you use to control these functions. This is not usually my favorite as it forces you to push the earbuds into your ears, and I find the solutions that the MW07 and the 1More TW use are much better. However, the buttons on the Tevi are not hard to push and for some reason they are just not really that uncomfortable. I don't know why, but for me it's not bad at all.Battery: The battery life is crazy good. I put these on a desk and played them for 7 hours straight at 75% volume and still had 20% battery left.Case: The case is very high quality and feels a bit like the Sennheiser Momentum TW case. While it isn't quite small enough to fit comfortably in a pocket (a bit disappointing for me), it is definitely not bulky by any means. Also, it provides like 70 extra hours of battery life which is great. It also has 4 LEDs that clearly show you how much battery is left, and even uses USB-C.Microphone/Calls: Honestly, this is what put the Tevi over the top for me. I've tried tons of true wireless, and the only ones that have been even remotely decent are my Airpods. While I'm not sure if I can say that these are as good or better than the Airpods, what I can say is that I walked around New York City on a windy day and made multiple phone calls with absolutely no complaints from the other end. Apparently my voice came through clearly and the people on the other line did not complain (as they usually do) when a loud firetruck or ambulance whizzed by me. Finally, some great sounding TW with great call quality.Connectivity: The Tevi have Apt-X and AAC codecs, which is great. So far I've had zero issues with connection once connected. Also, they connect very quickly and easily to my phone and computer, and will auto-connect when pulled out of the case. There is a verrrrry slight lag on YouTube videos on my phone, but honestly it really is so small that it did not make a difference to my enjoyment of the video I was watching. I will also update this review if I run into any connectivity issues going forward.Conclusion: These are the best true wireless on the market hands down in my opinion. All of it's features, it's fantastic sound quality, the great battery life, case, and call quality, all for $90 is just unbeatable. I'm sorry if this review felt like an ad for these things, but they're just that good. As I said earlier, the Tevi are a game changer and once people find out about them there is no doubt in my mind that they will rise to the top.
