Audio ExpressBT170 Mini 40 Watt Digital Bluetooth Audio Amplifier Includes 12VDC Power Supply

What's not to like? Inexpensive, sounds great, meets my needs, build quality seems better that average. Only thing I would like is a balance control, but I can cope without it. Gave it 5 star anyway.

It works great as long as your speakers are rated 40W or more. Anything less will cause distortion or possibly damage your speakers. I hooked this amp up to my 100W speakers and the sound is amazing.

Overall, this does exactly what it says it does: provides a Bluetooth connection, drives a pair of passive speakers, and has working controls for volume, tone, and bass. Compared to other ones in the same price range, I picked this model because it has Bluetooth and the power adapter is included in the price. I'm using it to drive speakers that were otherwise collecting dust, and it's performing as well as I had hoped for.Doesn't sound as good as my SMSL (also considered a "cheap" amp but $100+) and it hisses when the volume knob is set high (I turned this one down and maxed out the volume on my phone instead). Overall, if you order this with the right mindset you'll be satisfied on the price per performance.

Oh, where do I begin with the Audio Express BT170 Mini 40 Watt Digital Bluetooth Audio Amplifier? This little gem is like finding out your quiet neighbor is secretly a rockstar. It's compact, but boy, does it pack a punch! Driving my massive old speakers, it's given my TV sound a new lease on life - and at a fraction of the cost of those fancy sound bars. Plus, jamming to Spotify from my phone has never been this crisp. The tone range? Impeccable. Bluetooth and audio inputs? Seamless. My only tiny gripe? It's a bit of a one-device Romeo; doesn't like juggling multiple bluetooth device pairing relationships. But hey, in this age of commitment issues, it's almost endearing. All in all, a stellar buy! 🎸🔊🤘🏼

I was wondering what to do with my speakers I bought in the 80s. To think I used to have multiple huge components connected to them. Now this tiny device, the size of a pack of cards, delivers music just as strong and clear. I like that it gives treble and bass control along with volume.
