## Customer Reviews

### ⭐⭐⭐⭐⭐ Amazing
*by J***N on June 21, 2025*

Love this system! Got it for my studio apartment so I could listen to podcasts audiobooks and music everywhere. Even picked up a fourth speaker. It's so great to walk room to room and just listen to music without any interruption or problems.The sound quality isn't quite as perfect as my bose headphones, but this is also a multi room speaker system for under $1000, I'm not gonna compare it to $400 headphones. For the price the sound is AMAZING, and I do mean that there is nothing better under $1000.

### ⭐⭐⭐⭐⭐ Great little setup!
*by A***. on April 3, 2025*

I was a bit skeptical about these speakers when ordering them, not sure if I’d keep them long-term, but they’re a pretty awesome little setup.Sound volume and battery life seem decent for an ~$80 speaker, but I do feel other speakers at this price point might be a bit fuller with more bass. The controls on the speakers are a bit finicky, but easy enough to use, once you get them figured out.The flexibility of these speakers is where they shine though. Each can individually be unplugged and taken with you, and the whole set and receiver can also be fully portable with the receiver plugged into a portable battery charger.Input lag is nearly nonexistent, with the receiver in the middle of my house and passing through a few walls.I ended up setting this system up on an old AirPort Express base station, and connected 3 other AirPorts to the soundbars I already had, and these speakers work very well as filler speakers in the other areas of the house. I only notice about 0.5 sec of lag on one of the soundbars, but the rest are synced as well as I could ask for. All in all, I have whole home audio for around the cost of 2 Sonos speakers.Definitely recommend!!

### ⭐⭐⭐ Speakers-sound low. iPhone sounds louder. Speakers after 60ft stop working. Bluetooth only 6ft
*by C***  on February 18, 2025*

Speakers are not as loud. Works fine in a Livingroom or bedroom. Newer iPhone is probably louder than the speaker. This was purchased for a retail store, even after putting 4 speakers, volume is okay but not as loud. You have to be at least 10ft close to the Bluetooth device to work. I expected speakers to create a bridge to expand distance-doesn’t work. Any speaker 60ft away from Bluetooth device stops working. ONLY RECOMMEND FOR HOUSEHOLD.
