Indestructible apparently
Color: Blue
So I’m really clumsy and forgetful. I got these as a reward for not screwing up a cheap set for a month. Today I dropped the case next to my car but I was in a rush so I didn’t make sure I had both. When I got home, sure enough, one of them was sitting in the garage and I had definitely run over it. Let me just say, I am EXTREMELY impressed with the durability because I ran square over it and it works just fine. I gave them five stars for that but just know the case is not very secure. I’ll be putting a silicone tie over the case from now on. Sound quality and battery life are great and they look really nice. I also barely feel them on my ears and they don’t make me sore. Excellent product.

Great Price, Fit, Quality
Color: Black
Love these Open-Ear headphones. My previous earbuds were hurting my eardrums due to fitting inside my ear canals. These are more comfortable sitting outside of my eardrums. Great sound and fit for an affordable price. I use mine for exercising, walking, biking and they stay in place. Very pleased.

Good starter
Style: KIT
The chemicals are 5 stars, because the Chemical Guys make great and effective products. And they always smell good, but the taste doesn’t match the smell. I wish it came with other chemicals in the kit. But honestly go buy them one by one and get what you need.
