## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great. Fits great on head
*by C***. on December 2, 2024*

This works great and I really like the quality for to my ears and head. Great sound.

### ⭐⭐⭐⭐ Great sounding volume level low
*by S***3 on September 15, 2024*

I’ve been using these to drive a truck and the truck sound pretty much drowns out volume The sound that the announcer makes about whether the unit is on or off is louder than the volume that comes out of it can’t quite figure that out. Other than that, they sound great detailed sound kind of disappear on your head very comfortable

### ⭐⭐⭐⭐⭐ This is my second pair!
*by J***. on June 8, 2024*

I do a lot of walking for work, and these allow me to listen to music and keep a good pace. I simply hang these around my neck (so I can hear my surroundings) and turn up the volume. The sound quality is awesome, the light weight doesn't strain my neck, and not being IN my ears makes these extremely comfortable. As long as these are on the market, I'll probably keep getting them.
