## Questions & Answers

**Q: How many songs can this mp3 hold? 4GB does not seem alot?**
A: Depends on what type of the music you are trying to put into its memory. 4GB for AAC/mp3 type of pop music (3-5MB) probably just 750 music files can be put in them. However, if you put some better format, ALAC/FLAC 16-bit type of file (30-50MB), you can calculate how much you can put into. However, there is another option for this one is bluetooth. So if you have some streaming plan on your mobile device, you can use them on the go. These memories are only extremely useful, when you plan to take it go to swim. If you considering how long you gonna stay in the water, 70 music files, which is using the better format, it takes around 3.5 hours to finish a round. So it can be said enough. Because it a place for you to play music, rather than keep music in it. You can store your music in better method. Keeping them all the time in these flash drive type of storage platform will increase the chance of losing the files.

**Q: Does anyone with glasses use these?   And, if so, are they comfortable...do you still recommend these earbuds?**
A: Hello. Yes I would still recommend. I run wearing sun glasses and I mountain bike wearing goggles/eye protection. Never fallen out or had any issues.

**Q: Is an IPad Pro compatible in any way to link the device for drag and drop of files?**
A: Hi,

This Walkman should be compatible with iPad Pro 9.7inch, and you can check the compatibility for other devices through this link: http://bit.do/fTjrZ (copy and paste the link into your web browser).
And you can use it with MAC devices through our software ''Content transfer'': http://bit.do/fTjr3 & http://bit.do/fTjr5 & http://bit.do/fTjr8 (copy and paste the link into your web browser).

**Q: Can I have different playlists/folders?**
A: The newer versions are much more apt at doing this for you when you sync with Apple Music and you can then choose to shuffle play or opt for a particular folder when wearing them with the downloaded tunes.  My older ones that I’m now using again add the tunes you upload to folders too but they are not as well organised) lost the upgrade ones after 3 days lol…still gutted as they’ve sold out so I upgraded my piano keyboard instead when I couldn’t replace them)

## Customer Reviews

### ⭐⭐⭐⭐⭐ Gym Perfect
*by M***M on 19 February 2020*

I think I've had every generation of these types of Sony MP3 Walkman's and not every iteration has been an improvement on the last in terms of usability or fitment. I'm pleased to say that these are definitely better than my previous generation which, is a real relief given the cost uplift.That being said I got these for under £100 which, is less than a pair of half decent buds alone and you do clearly get more for you money. And a lot of packaging. And that's not entirely a good thing today - see photo.Firstly, sound quality. Good. Not superb but perfectly decent for gym use or swimming if that's your bag. The sound is not base heavy and is slightly bright which of course suits some music better than other types. I'm a metal fan and I like a bit more low down to get a good chug going which, I find is the perfect accompaniment to heavy gym lifting. It's perfectly acceptable but I found my Bose Soundsports better in that regard.The sound is perfect for voice though, and as I'm an Audible fan this is a real plus point. Speech clear and legible at all sound levels.One of the selling points is the ability of these to be used in water and in the spirit of investigation I have done so using the supplied ear buds that have a fine seal over the sound emitting orifice. The sound quality is in no way reduced as far as I can tell. It's still good overall. What is noticeable is that the volume level is lower which, is acceptable as long as you crank the volume up.Fitment and security of fit is brilliant. Absolutely superb. I'm not sure what sport you would have to be doing to get these to come loose but you would probably be at risk of your head coming off first. And despite the very good fit they are comfortable for long term use.The design is similar to all previous similar Sony players. Whilst not as small as Bluetooth only earbuds they are well crafted to sit flush to your head and stick out less than the likes of the aforesaid Bose Soundsports. In other words you won't look like an extra from the Star Trek bridge.Controls are easy to use once your memory muscle has kicked in and your fingers learned where they need to go.Where these are an upgrade in cost over the cheaper version is the addition of Bluetooth which, means you have options. You can stream media from your phone or suitable player as well as use the integrated MP3 player.The MP3 player is what I need for the gym because the gym I use is large and using Bluetooth earphones or buds results in dropouts if I leave my phone on a shelf. And I hate having to carry an MP3 player or phone in a pocket.One thing to note is that all my previous Sony MP3 Walkmen carked it suddenly after 18 to 24 months. This is irritating because I've had other players and wireless earbuds that work well past that point. However the convenience of these Sony's is enough for me to accept that every couple of years I'll need to replace them.Overall, I genuinely don't believe there is a better active MP3 player. Some alternatives sound better, haver better battery life or options but none come close to covering all the bases as much as these do.

### ⭐⭐⭐⭐⭐ Great with a very cheap addition
*by A***N on 10 July 2025*

Bought a couple of these over the last 10 years. Liked them but bothered me that the waterproof buds reduced and dulled the sound too much due to its membrane. Bought cheap 4mm Triple flange conical earbuds(they dont have the waterproof membrane) recently and on a 2 week holiday, the sound was fantastic and not once did they go wet and muffled. With these buds they are a richer sound than the shokz openswim i have and the controls are superior especially gor navigating audiobooks

### ⭐ Far too quiet
*by A***S on 21 June 2021*

Absolutely useless for swimming. I cannot understand why the designers can't allow the unit to go louder when playing MP3 files from memory. The surrounding water noise make it impossible to hear anything. I bought these because I wanted a set of headphones I could use for both running and swimming. In the end, these are decent enough running headphones, but there are plenty of headphones that do the same job.I bought these after they were compared favourably to Aftershockz Xtrainers as swimming headphones. Having used both, I can safely say there is no comparison. Avoid.
