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

You can continue to add speakers to the system
Very pleased with the sound of the Harmony 2 speaker system. I have multiple speakers throughout my home so I have music in every room! Love it

Pretty solid
Solid little speaker system. I set this up in 5 minutes. Had to google two things: 1. How to connect the bonus speaker that I ordered, and 2. how to connect via aux (then I realized that I'd connected to the output...). I tried Bluetooth streaming too and had no issues. We have the speakers set up in different rooms of our place and they're time-aligned, which was another thing I was worried might not be true.For the price, I'm quite happy. As other reviews mention, the bass is lacking and they don't seem to get as loud as I'd expect (maybe it's the three volume controls and I'll learn this is

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.

Not as Expected
The connection setup process for the speakers is not ideal. Once the setup is done and you disconnect from one speaker, you will need to go through the setup process again.

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.

Easy Solution for older audio equipment
We own a 100 CD changer, we really loved listening to our music collection with it. We recently changed out furnishing and wired speakers just were no longer an option. This set changed everything! I installed it in 10 minutes using the headphone jack on the receiver. The speakers can now be moved where ever we are! Family room, living room or out on the lanai.I have also tested it on my laptop and my iPhone thru Bluetooth, both worked wonderfully.
