Good for music listening, battery bad after 20 months.
Update Oct 23, 2018: Purchased Mar 2017, and 20 months later the battery will not hold a charge. This was used for music only so it wasn’t charged daily or left on the charger for extended periods. I only charged when necessary.Not so good (for my ears/hearing) for phone use. Battery life is good as I listen or keep connected for hours at a time.

Simple unique design. Works great.
I really liked this product. Unique design compared to similar models. Liked the simplicity of the three button interface. Sound quality was great. Battery lasted a long time. No problems connecting to phone. I would recommend this to my friends.

Battery lasts all day for my use
The battery may not last as long as advertised but it does last me all day which is what I needed. I can't comment on the sound quality, I can't hear well enough for that.

Needs some upgrades......
These are OK. I am not happy with the kick back sound they produce. Outside noise magnified. They tend to loose bluetooth connection which is magnified by the shouting of "Bluetooth Connected" when reconnected. It really hurts your ears!!!!!!.The cover for the charging connection does not stay closed..........

Great for light activities
The transaction was as expected with excellent packaging and product as described.Pros:extremely lightweightearbuds are contoured to fit into your ears snuglysound quality is decentdesign is elegantCons:the controls for volume are the same ones for changing a song which is slightly confusing and cumbersomeThe product would be perfect for a walker or someone doing a light activity. I tend to use Bluetooth headphones for HIIT exercises at the gym so the lightweight design was not ideal for that type of environment.

Lasted less than a year.
These lasted just under a year. They no longer hold a charge and are completely useless.
