Sony NWWS623/B Waterproof and Dustproof Walkman with Bluetooth,Black

I purchased this product about a year ago and initially, I was extremely satisfied with its performance. However, despite infrequent use—less than 30 times over the course of a year—I've recently encountered an issue where the device no longer powers on. Considering the investment made, it's disappointing to face such a challenge shortly after the one-year mark, especially given that my usage was sparing. It's worth noting that the product comes with a 90-day warranty, and unfortunately, I've also surpassed the timeframe for Amazon's extended warranty coverage. This situation is quite disheartening, especially because my initial experience with the product was so positive.

first of all, very clunky for water activities. the bulk at your ear means they can get blown off your head easily. secondly, the support is gawd awful. the app is completely useless, it wanted me to download macOS software to the iphone. when i did download it to the Mac, the computer would not recognize the device. which is a super bummer because worse of all, bluetooth no longer works. iPhone, computer, GF iPhone will not recognize these things. a lot of money=flush, cuz sony will not warranty them because they were amazon renewed... wore them 10 times. not a good value for the money ...

I've had these a few years now. I swim a few kilometers in a chlorinated pool over 60-90 minutes and they last longer than I do. The sound quality is excellent, better than AirPods or my Bose headphones, but not as good as Klipsch. The volume could be louder with the waterproof eartips on but, like others have said, it is probably a good thing for my sake that it isn't louder. I frequently listen on the highest volume while swimming. The bass absolutely SLAPS underwater. Bluetooth will NOT work reliably while swimming, the smallest amount of water will block the signal. You will need to load music onto it. This is because water is particularly good at absorbing 2.45 GHz (which is why microwaves use it). Outside the water, the bluetooth range is excellent. 4 GB is a bit small in 2021 (when I bought it, also in 2023) but it is plenty to load enough music or podcasts on there for a few weeks of working out without repeating content. Now that I bring it up, podcasts are probably the only thing I wish it were louder for.

They work exactly as expected and the sound quality is surprisingly good given the environment (swimming).I purchased these purely for swimming. I thought the bluetooth would be useful for walking to and from the pool but now I've disabled it since while swimming it connects and disconnects when I get closer or further from my phone - quite obnoxious.Do not wear these in open water swims unless you are sure they are safely attached. They will fall off with vigorous activity. I've slowly learned a few things about their attachment/positioning. First I wore a swim-cap to help hold the unit in my ears, but that was a headache - literally. Then after a few times of them falling off in the pool on a flip-turn push-off or a sprint I started putting the swim goggle strap over the headphone strap at the top of my ears. This seems to work very well. I also have noticed that if the earpiece is the optimum size for my ear it almost suction fits into your ear canal, and that also helps keep them on as well.I agree that the form of the ear-piece is not the most comfortable, but they do not hurt for an hour swim.When I first turn them on, using the waterproof/sealed ear pieces, the sound is excellent with surprisingly good bass. However, after a few times of submerging a few feet while doing a flip-turn they become noticeably less full throated. The sound quality is still good, just not excellent. I'm not exactly sure why but I suspect the air pressure inside my ears has something to do with it. I am sure there is no water in either the headphones or in my ear.What I don't like:Playlists? What are those? The method of getting mp3 files onto the device is slightly arcane and not particularly convenient. Over the years I had built up some swim playlists on iTunes, then modernized to using a streaming service on Spotify. Besides the fact that you don't have an mp3 file to load from a Spotify playlist even exporting one from iTunes is a two step process, and you better hope that the file is not in some protected aac format. I have an extensive library of older music in file form, so it's workable but no new music from Spotify are available unless I buy them. Then I just play one set of specific files on the unit through folders. There is some folder navigational control on the device. If you put your playlist files into a single folder then you can navigate to different folders/playlists with a double click on the previous or next button. Your play choices are: Normal play, repeat play, shuffle play, shuffle all. And a pleasant female voice often confirms what mode you've just selected.So besides the tedious playlist transfer I find this water resistant player very nice. So far so good.

I've been putting this product through its paces all day. Went for a run, swim, bike ride, and working around the house. No issues with audio quality (it is a bit nicer when listening to on-board storage as opposed to Bluetooth, but that's expected), and the mic seems to pick up my voice well especially for how far away it is from my mouth.Cracks me up that someone is upset they Bluetooth doesn't work through water and thinks that's somehow the fault of the product. That's why it still has on-board storage! And your mic doesn't work well underwater?! Jeez, shocking.The whole point of this product is to be both a waterproof walkman and a waterproof and dustproof Bluetooth headset.I wish there was clarification on whether or not we could order the finger remote separately, but that's my only 'complaint'. If any issues come up, I'll update this review.
