    • Perfect multi-speaker solution for covering a large area!
Style: Harmony 2
Great system! Works exactly as advertised! Great sound and with the 6 speakers I have, they all stayed perfectly in synch.

    • Great little setup!
Style: Harmony 2
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 .
Style: Harmony 2
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 .

    • Convenient and affordable, but easily affected by other nearby electronics.
Style: Harmony 2
I like the convenience of having sound throughout the house, and these speakers are more affordable than other brands. But they are very sensitive to other nearby electronic devices. If a computer, tablet, TV, etc. is located near a speaker, it can cause the speaker to make a crackling noise or even disconnect altogether, especially if the speaker shares a power outlet with the other electronic device. So you really need to experiment with the best placement of the speakers so as to eliminate these disruptions. ... show more

    • Sound great, super easy to use
Style: Harmony
Incredibly easy to set up. Works great. Saw reviews saying they weren't louder than a phone that is not true they are much louder and better sound quality. I am pushing the limits on the range of these but they function and work perfect. Very happy with the purchase

    • Extremely disappointed
Style: Harmony 2
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

    • Amazing
Style: Harmony 2
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

    • Great concept, poor execution.
Style: Harmony 2
The concept is great. Unfortunately the units suffer from poor sound quality. It doesn't matter what source you're using. The audio sounds tinny. I have smaller speakers that have better sound than these. They also have connectivity problems. If you use bluetooth, the streaming device has to be stationary. If you move, the audio breaks up in static and lost audio. Since the mobility that bluetooth offers was the entire reason for this system, it kind of makes it useless. I could understand if I was moving out of range of the units, but this was when I was testing them in the same room. I might have forgiven that drawback if the sound quality wasn't so bad. ... show more
