Review: Excellent little amp! - TLDR: I love it! In my home office I have 2x Gale Audio monitor speakers, and I was previously powering them through an old mini hi-fi, using an desertcart echo to play music. I wanted something smaller, and with better EQ controls (yes, the mini hi-fi had none) I also wanted the flexibility to add a sub at some point, so this Fosi 2.1 looked perfect. Initial setup with the 2x bookshelf speakers - the sound is already nicer than the old hi-fi - and such a small neat package too. I had to run it around 3/4 volume, as I want the alexa to control the volume, but that's fine. Other reviews have mentioned hiss, but I dont have any. Then I remembered I had an old sub in the attic, so I went and got it, couldnt get it working in active mode, so switched to passive, and I have to say it further improved the sound again. I'm really pleased with this little amp, it is very neat and tidy, and does exactly what I wanted it to do. Thoroughly recommend if your use case is similar Review: Great little amp! - Great little amp. I paired it with Klipsch R 41m's and it can shake the room when pushed no distortions that I can hear, pretty amazing. It does have some static noise coming out if you crank up the dial with highs but its only audible when you dont play anything; when music is on you cant hear it. I cant say anything about the sub output since I dont have a sub. The bluetooth connection works great. Great value for money no regrets whatsoever. ## Features - 2.1CH Bluetooth 5.0 Power Amplifier: This amp boasts an exquisite design, enhanced operation, and exceptional sound performance.

Of course all is not perfect (lets not forget its and 85 quid mini amp) and where this little digital amp falls down is on refinement to the music, it's a little course and hard in the treble quality and lacks the fluid creamy sound of a good hifi amp so it's certainly not a substitute for a good hifi amp but as a bedroom setup or for the computer it's excellent. I then connected it to my THX soundworks computer speakers and 8 inch passive sub and again it proves excellent with more power and punch than I will ever need, even with the standard power brick it has lots of usable volume. Bluetooth sounds just OK as you'd expect and the signal is stable BUT the major flaw in this unit is ANYONE ELSE CAN CONNECT AND PLAY MUSIC OVER IT via Bluetooth WITHOUT your permission as it does not have a pair button or ask for a code on your phone, this is really stupid and why I have only given 4 stars. ## Frequently Bought Together - Fosi Audio BT30D Bluetooth 5.0 Stereo Audio Receiver Amplifier 2.1 Channel Mini Hi-Fi Class D Integrated Amp 50 Watt x2+100 Watt for Home Outdoor Passive Speakers/Subwoofer Powered Subwoofer - FosPower Banana Plugs 10 Pairs / 20 pcs, Closed Screw 24K Gold Plated Speaker Plug Connectors for Speaker Wire, Wall Plate, Home Theater, Audio/Video Receiver, Amplifiers and Sound Systems - Kinter Cable 100ft 16-Gauge Audio Stereo Speaker Wire Cable, 100 Feet, 30.48 Meters, 2 Conductor, Polarity Marked, Flexible Clear PVC, CCA, Home Theater, HiFi, Surround or Auto Amps --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/105057373-bt30d](https://www.desertcart.in/products/105057373-bt30d) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-23*
