Pyle 200W Stereo Power Amplifier with Bluetooth - Dual Channel Audio Receiver - LED Display - RCA - USB - SD - MIC IN - FM Radio - AUX Input - Perfect for Home & Computer Audio - PDA29BU.5

Anyway, I figured for the price-features this thing had, there was a good chance some aspect of it will suck, but it was still worth the gamble. I was way wrong. I purchased this in thing about 6 months ago and I use it EVERY DARN DAY in my office. It takes standard USB drives and TF cards. (Also has FM which is always fun for a few minutes)Ease of assembly/use: Plug it in. Turn it on. I added a few old high quality speakers, and having to strip new wire was the toughest part of the install.Quality: Crisp and clean. No feedback, now hums. The most I've had this to is ~50% volume and at that level, it provided goosebumps -- well, at least for me.Bonus: I was going thru the box and found A REMOTE! It was like finding $20 in an old pair of jeans. I could now sit anywhere in the roam the office and crank the tunes. Pics show the unit under my monitor and another with a bit more zoom to show the remote.For the price and quality, this was one heck of a sweet acquisition.

I just want to write that this is a great little unit AND I read in another review that the remote control did not work well because of having a very short range, well, that is what happened to me as well. THEN I thought that it might be a battery problem. So I replaced the batter with a new one. Now it works great.

Pretty darned good for a $30 amp. Clear, clean Bluetooth, excellent FM radio reception, aux inputs play back loud and clear. I put the output into a pair of 6 ohm Yamaha studio monitors and it sounds fine at lower volumes; quite a bit of distortion at higher volumes, but who listens a at full blast?Overall, excellent little amp for the money. Not audiophile quality but good enough for everyday use with passive speakers.Use the tone knobs to dial in your speakers’ sweet spot.Demerits for no balance knob.

Do not let the size of this amplifier fool you. This is a power house of power in this small amplifier that will meet your needs. I would recommend this product.

Unit is compact and easy to hook up. Great Bluetooth range and sound. Well worth the money.

Getting to the punch line right up front. I'm going to try to return this thing. I'm very frustrated. I feel like they should actually pay me for the time I invested in unboxing, hooking up and trying this thing! But, if I am being fair, if I had gone and read some of the negative reviews, (which call out exact complaints I have experienced), I would probably have moved on to a different choice. So, in the ugliest sense, I own a little bit of this because I should have done a little bit more homework.Noticeable backround noise starts when you turn on the power switch, even with no program content, volume at any setting (0 - 100 %). As far as how loud this noise is: Not as loud as normal conversation. About the same level as you might want your music if you just wanted to hear it but want to not wake up anyone else in the house, or be able to easily talk over it. Maybe the level an quality/character of a running clothes dryer 5 feet away from you (complete with the higher/lower events from clothes rolling around inside the drum).So that's the noise issue.The second one is that the remote functionality is horrible. it's hit/miss and I am pointing the remote directly at the machine with my arm stretched out at it. Remote winds up being maybe 5 feet from the unit, and still does not consistently work.Finally, if you plan to use FM feature, and you think you're going to want to move between stations, then pack your patience. It is a PITA (pain in the ...). For me, it was a "don't care" because my only use case for this thing was going to be BT streaming for music in my study while I work.Really, the only things I like about this are the concept (which is why I purchased it). The small size, BT connectivity (with FM for very occasional local news or music if internet went down) and quoted power all that I needed for this thing to do. If only it could have actually done that.What application would be OK for this? Well, if you're going to "set it and forget it", picking a station or BT source once per day and let it run in an environment where you have a decent amount of base background noise (a store, a workshop with machinery running), then this unit, at this price point, might be able to work for you. It certainly doesn't work in my home study where there is no background noise, the desired music volume might be low, and the ability to easily change setting with remote is important.

Mine doesn't hum at all, at any volume, connected or floating. The radio controls are very clumsy - scan first, then select from the list of all the stations it picked up. No way to enter a particular frequency. Bluetooth connects without any issues, and has very good range. Couldn't care for the remote. The amp sounds fairly warm, but is far from 2x100w. The chip inside is a 4x7w amp, so assuming bridging it delivers 2x14w max. Good enough for a pair of ancient Avids in my garage, although I don't appreciate the marketing lies. All in all, this Pyle is on par with what you'd find on AliExpress.

Great product, has no issues
