## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great for working out
  

*by R***A on Reviewed in the United States on June 16, 2019*

Even with running, these earbuds don't fall out. The little part that sticks out and hooks into the outer part of your ear didn't bother me either. I do take an alcohol wipe to clean them because after working out, I can see the sweat all over them. This has not damaged the earbuds at all. Even the silicone hasn't cracked nor do I get black on the wipe from the silicone. The only issue I've had are a few people accidentally connecting their phones with my earbuds while its connected to mine. Other than that, great sound quality.

### ⭐⭐⭐⭐⭐ 







  
  
    Quickly became my favorite earbuds
  

*by M***E on Reviewed in the United States on February 26, 2020*

I'd say these are a great value for a few reasons. First, they are sturdy and have a little heft, but I can wear them all day and it isn't painful at the end like my old earbuds were. Then.. The sound. I wasn't expecting good sound I'll be honest.. But these have great deep Bas and get super loud. I wear them around sometimes with no music on because the noise canceling is so good and the microphone sounds clean for phone calls or using snapchat. I'm going to buy another pair for backups in case I lose these. They are that good, they feel and sound great and for like 18 dollars shipped its one of the better earbud values on Amazon.Edit: 4/22/2020 - I use these things like 5 hours a day.. and recharge every other day. That recharge to get 10 hours takes about an hour. I do not understand why these are so cheap? the sound is amazing and they are comfy, something most sub $30 earbuds are. I'm buying an extra pair just in case these get lost, i cant say enough good things about them!

### ⭐⭐⭐ 







  
  
    Not the biggest fan but cheep is cheep. 2.9 rating for me out of 10
  

*by J***S on Reviewed in the United States on December 7, 2019*

I am not a big fan of the sound.I own a lot of various Bluetooth headphones with that said the bass is fading when it hits and the left ear head phone on my set was not as loud as the right witch is a big issue with my set. There cheep and good for a back up but not your GO To set...
