    • Great concept and exceptional customer service. Extraordinarily responsive
Very happy with this purchase. And I have to say the customer service is outstanding even with the holidays. One of my speakers was not pairing. ChatGPT and I couldn’t get it to pair. I reached out on Christmas Eve Eve to customer support and they responded just after midnight on Christmas Eve. Their first suggestion didn’t work, but their second suggestion later on Christmas Eve did work. So far I am very pleased with the quality and sound and just the general concept of this set-up. ... show more

    • Amazing
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. ... show more

    • Good value for the price but has issues with charging and connections.
Love this set but have one speaker that continually disconnects itself. It’s a pain in the A to keep charged and connected but didn’t want to spend $800 for Sonos. I have 5 speakers set up and sound quality is good for the price. I wish the Bluetooth range was longer.

    • Extremely disappointed
Worked great for 1 day. Now the sound pulsates from high to low out of one of the speakers.And they all crackle like i'm listening to vinyl. It should also be noted that the frequency appears to interrupt wi fi signal. These look and feel like quality speakers. Unfortunately looks can be deceiving. It should also be noted that they come with 4 usb wires for power and changing, but not even 1 wall adapter for power. If you plug the speaker in for charging while listening, when the speaker reaches a full charge, it turns off. The design of this system has a lot of potential and I thought it was exactly what I was looking for. Unfortunately , the subpar quality that people mention in the reviews does exist. ... show more

    • Great little setup!
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!! ... show more

    • 2-3 second delay of audio to television .
Good sound system; initial set up was not as easy, but after a few tries, works well. BIG HUGE DRAWBACK- the sound from television is about 2-3 seconds delay so the voice does not come out at the same time as the broadcast. Quite disappointed and rethinking whether to send it back or not .

    • Great sound quality
Absolutely love this system! Easy to use or connect multiple devices. We ordered an additional three speakers and everything is working together beautifully.
