## Customer Reviews

### ⭐ Static-Filled Junk with Broken Interiors
*by M***N on July 10, 2025*

I rarely leave reviews, but this purchase was so frustrating I had to speak up. Right out of the box, these speakers were a disaster. Constant static, distorted audio, and absolutely no clarity — completely unusable for anything beyond background noise (and even that’s being generous).Thinking maybe something could be fixed, my husband (who has years of experience with electronics repair) opened them up. What he found was appalling: both speakers were cracked and broken on the inside. Not from shipping, but clearly poor manufacturing and zero quality control. The internal components looked cheap and haphazardly thrown together.For the price, this is nothing short of a scam. These shouldn’t have passed any kind of inspection — assuming they were inspected at all. The pair were completely different speakers! We expected basic functionality at the very least, not pre-broken, static-riddled junk.

### ⭐⭐⭐⭐⭐ high quality, simple, and easy to use
*by J***N on November 17, 2018*

it look me less than 5 minutes to install, connect to my phone and start playing red hot chili peppers! these speakers sound great no the most base but the mids and highs are crisp and clean. also remember these are full 6" not puny 4.5" speakers. they are big loud and proud. These are perfect for utv's or boats. it comes with a plug charger and a cigarette lighter charger to charge in the vehicle. honestly these are fantastic, in the future i will update but as for the first week i love them!

### ⭐⭐ Broke after a few outings
*by C***B on May 13, 2019*

These speakers worked great for a few trips out then the clamp housing broke. The sound was good and easy to mount and take off. The battery life seemed to be very long.
