Avantree Harmony 2 – Multi-Room Wireless Speaker System with Bluetooth & Wired Inputs, Easy Setup, Expandable, 30ms Low-Latency Sync for Whole-Home, Meeting Rooms & Small Indoor Events

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

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.

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.

Works great! Simple Bluetooth hookup, but you must keep you phone close to the receiver.

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.

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 .

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!!

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.

I've been on the market for a multi-room speaker system for a couple of years and finally I decided to take the plunge with these. A lot of these types of products require you to download an app and/or create an account of some kind, but all I wanted was to be able to pair and play; thankfully, this system does exactly that. Very simple to set up: just put the base somewhere handy, switch it on, pair it with the device of your choice (PC in my case), turn on the speakers, and you're sorted. You can also connect the base to your audio source physically if it has the right optical or auxiliary output. For their size and price point the sound quality of the speakers is perfectly acceptable, and they have a nice sturdy feel to them. The ability to use a single speaker on its own instead of as part of the multi-room system is a nice bonus too. All in all I'm very happy with this purchase, and will most likely be buying an additional speaker soon. If you're looking for a similar system and aren't a hardcore audiophile who must have the absolute best quality always, I'd gladly recommend this to you.

Thank you Jeany for all your help. Our system has become an integral part of our working environment and works seamlessly. When I had to sort something out, Avantree’s customer support, in particular Jeany, was outstanding.

Super ! Guter Klang.. leicht zu bedienen.

Bestes Lautsprechersystem für einen angemessenen Preis. Ich habe das in einem Restaurant eingesetzt...echt klasse

We love our speakers. I had a single speaker, but both my husband and I are hard of hearing and need to have a speaker near our good ear. Now we each have one and the sound is awesome. We can each have the volume exactly right for our own need. When the cleaning lady comes in, she is able to put the third speaker wherever she is working. Usually though, I keep the third speaker charging and rotate the one on charge. I had trouble setting them up until I realized that the speaker won't work while it is charging. Once I understood that, it was easy.
