Improvement on previous model.
I bought this for my wife, as I have an older model. The improvement of Bluetooth is great for listening to the radio in the hot tub!

Great sound...
I bought it one year ago. It is great product. Nice sound and useful. I can advise it. Only one problem there is not alert for finish battery. It is say low battery and close.

Average and overrated
Sound quality is just average. Bass is almost non-existance. Bluetooth connection is delay and not sync with video.

Great product - True Wireless Earphone
Good for me going on running. Songs are stored in the earphone itself. Need not to carry my handphone along. Once connected to handphone, it is able to pair to answer incoming call.

I will give the last star if Noise-Cancelling is added into the earphone.

Great Waterproof earphones
I have been using the Sony waterproof walkman for swimming almost on a daily basis and I am very happy with the sound quality of it both under and above water. They are fairly stable on the ears as they do not fall off when I do freestyle turns while swimming either.
It is fairly easy to use with the MacBook to download music onto the inbuilt MP3 player.

Disappointment over and over
1- Doesn't pair easily and have to manually pair it every time I use it.
2- When wanted to download music , I needed to download my music from Spotify to another SW then download my songs into Sony. i tried a couple SWs and didn't work so I lost this option. (too much hustle)
3- I usually use it 4 days a week when running. I stopped for 10 days and now it's dead.
4- Went to the store to check on the warranty. after 6 months by 1 day , its void but they said the problem is in the base charging which they don't carry.

Overall, I think its too much for a headphone.

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.
