Good product

Reviewed in the United States on December 28, 2023

I use these for swimming laps in our community pool. I first had set of head phones from another manufacturer that were bone conducting technology. I liked them but they quit working after about 3 months. I used 4 pair in one year until the manufacturer warranty ended.

I bought the Sony pair and foung the sound quality was way superior to my prvious pair. When you use the water proof ear buds the volume is a little lower but that is fine. I was told that they would come off during swimming when you push off the wall. Has not been a problem at all.

After one month these just died. They will charge but will not turn on. I tried the restart and hard reset operations and neither worked. I can’t get them to turn on.

Good features but limited functionality

Reviewed in the United States on October 6, 2022

I have TWO pairs of these headphones. I apologize for how messy my ear tips look and my original device.

The good:
- you have a bluetooth and mp3 player mode (you have to pick one)
- can pair with 1 bluetooth device at a time
- is water proof (even salt water proof; hence why sony includes the silicon tips don't ignore that)
- can be an mp3 player in a world where stand alone players are a luxury
- can last 8 hours if used only as an mp3 player

The bad:
- you have a bluetooth and mp3 player mode (you have to pick one; you may not like this)
- no LDAC, AAC, etc. Just normal SBC
- files MUST be mp3 (no ogg, m4a, flac, alac, etc)
- the mic echoes or catches ambient noise on the side of the person you are speaking too (noise canceling is just for you)
- the mic will break if you dive with these after a few weeks/months
- the contacts will rust after 3 years of use in salt and fresh water (please see the light green on the contacts in the picture on the golden charging contacts on the inside of the band)
- lasts about 6 hours connected as a BT headset

I have learned to love my headsets based on the features they provide for me even though there is no LDAC or AAC support. In spite of the lack of HD audio, this player provides a very welcomed feature in modern day where I can pair it with my phone but then just ignore the phone and listen to music. The mp3 requirement is a hassle I wish Sony was okay with OGG or even M4A as this allows us to put in more music with less file size given the hard 4 gb (realistically 3.4 Gb) storage limit. Its also the only certifiably salt water proof mp3 player. The silicon tips really help prevent corrosion in the driver. The reason why I have two is because after using one pair in the pool and ignoring this care requirement, the driver on the left side (where water would mostly go in) would leak into the driver and now makes the sound a little unbalanced.

if you must ignore the silicon tip advice sony provides to hear your music more loudly under the water, I would suggest looking for some triple flange earbud tips. The three flanges prevent water from leaking into your ear, nice, and also prevent water from seeping into the driver also. You want to get the ones with the opening pictured here because while it may seem like they won't fit the sony mp3 player, they will its silicone and its meant to stretch. You want a really right fit on the bud as well as your ears to ensure a good seal to prevent water but also have a decent level of loudness when doing lap swimming.

It works really nicely the noise cancellation is amazing. Especially when. It's off I can hear what I need to hear at work to be safe. The earbuds though hurt my ear really bad.i had to put different ones that were softer or else I would have a miserable time and no earbud has hurt my ear like this. It was also due to the fact I was wearing a beanie with it which didn't help either. All in all it is really nice and easy to use.

The best waterproof walkman out there

Reviewed in the United States on April 7, 2022

Color: BlackVerified Purchase

I've owned 5 Sony waterproof walkmans in the past 10 years. They change design every time I get a new one. The one I bought in 2022 is the best in terms of sound quality and fit. Perfect for swimming and showering. Don't shampoo while wearing it though. It's great that you can save songs in it to listen while away from phone swimming. Bluetooth is great in shower or working out near phone. I love the hard buttons on this instead of touch gestures like the other brands which get pressed unintentionally. One of the best gadgets I've had in my life. If they ever decide to stop making it, I'm literally gonna buy like 10 of it to last until I get old and deaf lol. Totally worth the price. It's not brand premium, you pay for the quality and functionality.

Old reliable and improved.

Reviewed in the United States on March 20, 2023

Color: BlackVerified Purchase

My old one died after a few years. Buttons, I think. Or at least that's what a consensus of reviewers implicate.

I tried replacing the old Sony with a highly rated bone conduction unit. Just awful. I use this for listening to audiobooks while I do laps. The thing was unintelligible and changed volume and quality every time my head cleared the surface. The experience was sufficient to motivate me to pay the extra for this newer Sony.

Back to old reliable now with two notable improvements. 1.) Bluetooth. Useless in the water but works just fine on land. 2.) Loud mode. Because the headset is pushing the sound through membranes on the waterproof earbuds, it's greatly attenuated. Plus my ears are no longer young. I used to get around this by running my audiobook mp3's through a volumizer app to up the output at the source. With this new version, in LOUD mode, I no longer have to pre+process the files. Maybe loud is to strong a word but it's now at least loud enough underwater that I can hear the story without enhancement.

I just hope Sony keeps making this. Even if the buttons fail every 3 years, I'll keep replacing this because for audiobooks, there's nothing that matches it's functionality. And I'm talking about it's ability to store mp3 tracks in nested folders and easily navigate track to track, chapter to chapter, and book to book. You're not stuck being reliant on mp3 tags and playlists like with most players which invariably get your files jumbled and simply don't work for books.

I really wanted to like these....

Reviewed in the United States on August 29, 2022

Color: BlackVerified Purchase

I've had these headphones for about 3 months now. I've given them a fair amount time, and I'm going to move onto something else. I bought these for stand up paddleboarding, so I can't comment how good/bad they are for swimming, but i do need a set that is waterproof. I also want mp3 capability because sometimes I just don't want my phone with me. Paddling is something I do to get away from my phone....

First off, I had low expectations for sound quality. any sound transmission is going to be compromised by water proofing and it's not like streaming or MP3 sound hi-fidelity to begin with. These sound marginal, but seriously, that's kind of ok.

Battery life, it manageable, but not awesome. I have to recharge every other workout. The worst part is you don't really get a warning, nor can you tell how much charge you have left. Having your headset die in the middle of a work out is a bummer.

The real deal killer here is that I just don't feel safe wearing them. First ambient sound mode only works while streaming. Second the swimming buds really block out to much of what is happening around me, namely boats and jetskis. Granted, I've been hit by a careless jetskier once, so I'm a bit nervous on a good day. I keep the volume really low, and try to keep one but only partially inserted, but it's just not worth it, I can't really hear the music wearing them this way.

These just don't work for me.

Lo-mid tier earphones

Reviewed in the United States on June 17, 2023

Great sound quality when using the dry ear-buds, reasonable sound quality when using the water-proof buds.
Excellent ear seal for normal ear canals (ruptured an eardrum trying to pop them out the first time)
Poor battery life (especially overtime). Started out 6 hrs, dwindled to the mid-4s pretty fast. No real heads-up on battery life, just 'low battery' mid-workout or conversation and then shuts down.
Didn't expect too much from Sony, was about as disappointed as I thought I'd be.

Functionality, yes!

These are not for you if you are after high quality sound. I did not buy these for that, I bought these for their functionality. I've thought maybe six pairs over the past 10 12 years, and I love them. Don't have to worry about them getting wet, don't have to worry about bringing my phone with me for music, great on the beach when I'm skimboarding and then but I'm not on the beach I use them at home everyday ripping through the trails and working out.
