AvantreeHarmony 2 - Multi-Room Wireless Speaker System with Bluetooth & Wired Inputs, Set of 3 Speakers with Independent Use, Scalable up to 100, Low Latency Sync for Home, Outdoor, Church & Events

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!!

One of the best items I’ve gotten for the TV/Movie experience. Now the speakers are so close there is no need to blast the volume just to hear the quiet parts. Also the customer support is amazing. One of the best companies I’ve dealt with in a long time. You won’t be disappointed with this purchase.

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.

Ease to use but makes white noise

love it! very easy set up and good sound!

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.

These are easy to setup and link right out of the box, the sound quality was crisp and clear, ran for 4 hours on a single charge. Great value and built solid, great functionality

The convience is nice to have multiple speakers throughout the house and yard during a party but the sound quality is not very good. The speaker vibrates/distorts with any real volume and even at low volume I cringed, listening to my favorite female vocalist.
