It wasn't there! Best buds I've purchased thus far! I have other Shokz which I use for meetings at work and those are great. However, these buds are phenomenal for going everywhere! Like walking, at a restaurant, waiting in a doctor's office, traveling, etc. I can hear my surroundings while I can listen to music or books. What I'm amazed is that it has bass! Again, great purchase! I might buy another one in the future.

Fantastic headphones that sounds great and stay where they are meant to. Only a slight problem where I try to put them in the case and they are still connected to my phone. This is more than likely my fault, just got to figure out what I'm doing wrong.

I bought Shokz because I wanted to try something other than my AirPods for running. So far I've been loving it. I was worried they weee going to move around or potentially fall while on a run but they didn't! The best thing I like about it though is my kids can use them as well! They don't fall off my 5 year old's ears! Sp glad I found these while they were on sale.

Superb quality, sound great, look great!

Great product and the most comfortable.

Great sound. Quick Bluetooth connecting.

These are some of the best sounding ear buds that I have ever purchased. they have a great sound.

The sound is wonderful. The fit however seemingly great at first ends up hurting my ears. Bummer.

These stay put and the sound quality is great.

Light and easy! Amazing little ear phones!
