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. Review: 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. ## Features - Multi-speaker system: The Avantree Harmony comes with a transmitter and three fully synchronised wireless speakers. Place the speakers throughout the room or even in different rooms and enjoy an immersive stereo experience of outstanding audio. - Easy setup: Once the transmitter and speakers are turned on, they connect automatically - manual pairing or the use of an app is not required - High-quality sound: the double drivers and bass radiators in each speaker ensure extra loud and clear sound. - No sound delays: With a latency of less than 30 ms, the speakers work perfectly synchronised without any audio interruptions or delays. - [EXPANDABLE TO UP TO 100 SPEAKERS] Expand your home speaker system by adding up to 100 Harmony speakers while maintaining low latency.
