Surprisingly Good
Color: Black
I got these over a year ago for less than $25 and I’m surprised with how good they are. I needed something in a pinch just for calls and expected a product that would sound horrible when listening to music, but these inexpensive earphones sound pretty decent.
They have an app that allows you to use different equalizer settings giving you rich sound and bass either using their presets or you can set custom EQ.
I like that these are over the ear so you can enjoy your music and still be aware of your surroundings. They are light and comfortable, so much so that I almost forget I’m wearing them at times. The hook over ear design is secure enough that I don’t feel I have to adjust them often like earbuds that constantly feel like they’re going to fall out of my ears.
You can also use the app to customize the touch features on each earpiece individually and there are lights on the earphones that you can turn on and off and set to different colours.
The batteries last a long time, up to 8 hours on a full charge (when not using the lights feature) and they charge really quickly when you put them back in the case.
The only thing I don’t like about them is you can’t tap them to answer calls, which is why I bought them. At least I haven’t been able to figure out how to get that to work. But other than that, I’m pretty satisfied with my purchase.

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.
