## Customer Reviews

### ⭐⭐⭐ GOOD EARBUDS
*by K***Y on 20 March 2021*

Works well

### ⭐⭐⭐⭐⭐ Recommend
*by E***T on 5 December 2017*

I like them a lot they are very loud volume controls built in had to read the manual before using as I didn’t know how to get them in pairing mode

### ⭐ Not great quality.
*by P***  on 5 September 2018*

I liked these at first but the sound is very intermittent. It now only plays out of the right ear if at all as often breaks up which is very annoying in a middle of a workout.
