## Description

desertcart.com: Avantree Harmony 2 - Multi-Room Wireless Speaker System for Home & Office | Sync Multiple Speakers Across Rooms with Low-Latency Audio, Bluetooth, AUX or Optical, Easy Pairing, No Wi-Fi or App : Electronics

Review: 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 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!!
Review: 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
*by S***N on August 4, 2025*

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 isn't true later). If the alternative is a wi-fi- or cord-based setup to play music in multiple rooms, the security/cost/time savings is definitely worth it to me. Place them on top of a cabinet and the bass should be slightly better. Would recommend as a former skeptic.
