Sony Waterproof and Dustproof Walkman with Bluetooth Wireless Technology (4GB) SKU: NWWS623B

Rated 4 out of 5 by from Good for swimming but has issues Bluetooth stops underwater. This unit apparently has the bluetooth receiver in the right earpiece which is more frequently underwater when a right handed person swims freestyle (our heads turn to the left to take each breath.) To keep the music playing it is necessary to stroke harder with the right hand to keep the right ear at the surface. Putting the receiver on the left would be better for most people. Raising it above the head with an antenna in the back could solve this issue for everyone.

Rated 2 out of 5 by from Expected More I Brought the Walkman series in a duty free shop in Bangkok airport. The expectation from Sony was really high for me. Even the shop guy convinced me to buy Sony. But now I feel there are three major issues with it... 1) The inner ears start hurting so badly that after maximum an hour its a battle to wear it for more longer time. mostly like Pain vs need kind of a scenario. 2) The battery capacity of the Walkman is quite poor, hardly 2.5-4hrs backup.... depending on the mode... if on Bluetooth its just 2.5hrs otherwise it might go up to 4 hrs. 3) The sound output is not that great.

Rated 5 out of 5 by from All in one device I've had this particular model about one year. I have swam with it a couple times and found the waterproofing to be superior to previous models. The drivers they use in these seem to be prone to be crackling. After using them about three weeks, I noticed that I would get intermittent cracking when listening to certain songs. This is something I'm hoping the sill address on the next iteration. I don't feel like putting up with Sony's subpar customer service to get it fixed. The Bluetooth connectivity is seamless. It syncs well when I'm watching Netflix and transfers to calls with ease. The battery life seems to be all that they claim. I haven't been able to kill the battery without going multiple sessions without charging. The ambient listening mode is great, but only works at lower volumes. It seems the microphone and or speakers doesn't adjust sensitivity for the volume you listen to music at. Still a great idea and nice to have the option. The charging cradle is simpler and much more durable than pervious models. Glad they seem to have fixed it. Overall great product with some minor issues I can live with until the next model.

Rated 5 out of 5 by from An amazing product I purchase this product about a month ago and must say I truly love this product, I use this product on my daily walk and love the fact that I can listen to my music without having to carry my phone with me

Rated 5 out of 5 by from Best in Class I'll be honest, I bought these bad boys (NW-WS623) after seeing the NWZ-W252 Walkman featured in MGS Peace Walker. I did some sleuthing and saw these new ones included other features like Bluetooth and Ambient Noise that I really like. When they arrived, I couldn't have been more satisfied with the feel, sound, and technical aspects of the earbuds; much better than any other comparable wireless earbuds I've ever owned and absolutely perfect for exercise and just being aware of those around me with the ambient noise mode.
