My second headset for swimming
My old water-resistant (or not so much) headset stopped working due to an internal short circuit. It can charge but then switches on and off randomly until it is empty again. Play button also doesn't work anymore. Since this is not a repairable item I bought a new one. The new one only has 4GB storage - sad. The sound is a bit better and it has the sound pass through function. Rest is practically the same. Let's see how long that one will last.

Warrantee invoked after just two uses
I was super excited as I swam underwater in the pool with music for the first time, but unfortunately that would be the penultimate time too.

After the second use the right headphone ceased emitting sound and I had to return the product. Hopefully it was just a blip and when returned from warrantee it works.

disappointed since I went with Sony because I expected quality

Was Disappointing coming from Sony.
I bought the device about a month ago and right now I am using it only for swimming and nothing else. The only thing I like about the product is the fit and the fact that it is waterproof. On the other hand the many disadvantages I feel are:
1. Short battery life on Bluetooth play mode. (Approximately only about 3 hours).
2. Absence of warning of low battery level. (The moment the low battery audible of low battery is heard the device stops functioning immediately).
3. Sound quality in MP3 player mode is disappoint. (Bluetooth play has better sound quality as it it boosted by the phone's music app sound enhancement features.

Great Companion for endurance swimming.
After so many consideration, I have decided to buy this product and I've purchased this 3 times. So far, it is my loyal companion in my swimming.

A few things for improvement :
- memory capacity needs to be increased
- need to improve quality of the mechanism, my second one was already had glitz only after less than a year usage, luckily the service center replaced it for the new one but I also bought the new one cos I couldn't wait for 2 wks (I had to swim the next day). My first one was lasted a few years.

Perfect Earphones for Workout
Bought this about a month back.
Very good for a workout & running - stays in the ear, without slipping or falling out. It's very light, so is not uncomfortable even over 2-3 hours of use
The buttons are quite easy to navigate, and provide wireless access to practically all major functions.
Sound quality is surprisingly good for this price-point !
Battery life is also pretty good.

Product for swimming
The product is suitable for swimming, but swimming earbuds will impact the audio.
It is considered slightly heavy for regular usage and will burden your ears if used for an extended period.

Swimming can never be the same
I wanted some music whilst doing my swim workouts. MP3 is a great feature as Bluetooth needs my hand phone nearby and it don’t work in water. The buttons need getting use to. The ambient function is good. In pool, I want to only listen to my music. On my runs, I want to hear the surroundings for safety. This product did it all. It’s just a little bulky. If it’s slimmer, would be awesome.

Enhanced Funky Design
Am so happy I bought this. My previous similar but older design lasted me for 5 full years. Though it's still Good, the battery tends to die off faster. And so I bought the updated model..

Love for a dip
This was my third pair. Slight improvement on the charging adapter but the charging contact point between adapter and ear phone can be improved as the last experience was due to loosen in charging contact point.
As for sound quality is almost same, hope it can improve in future.
