Surprisingly good for the price. The only thing missing is a headphone jack but...it's a little power house and well drives my bookshelf speakers. It has presets and the Bluetooth connects easily and as expected. I'm going to mount this under a top cabinet in the kitchen. Don't expect much from the manual as it is written in very broken English but you can still figure it out. It also comes with a standard AC cord so you don't need to fuss with a DC wall wart. It comes with a small remote as well. You can't go wrong for the price. FYI - In the rating questionnaire it asks about "Sheerness". I have no idea how that applies here. P.S. - I have a few additional comments regarding this item after reading some of the other reviews. 1. Quality - some folks have had issues after running the system. Since my review was written days after receiving it, I can't comment except to make sure you put it in a location where airflow to the unit is not blocked. So far, my unit is not getting hot. 2. Sound quality - Folks, this unit costs $45 dollars. If you are and audiophile and into studio quality sound, then I think you are expecting a bit much for $45. I'm a music lover and it sounds plenty good enough for me. I've listened to YouTube music videos and some FM music stations and it sounds pretty good to me. It does go louder than I need and I get some decent full bass sounds from my bookshelf speakers. If you expect 130 db rap or pounding rock or the fine nuances and dynamic range of the 1812 Overature, then this unit might be for you. But aside from the long term potential quality issue, I'm quite pleased with the unit. If you are happy with the quality of music over your cell phone, this will do just fine and my wife is happy listening to Bocelli over this unit. So, since I've already belabored this issue, I'll repeat, for $45 you get a very small unit that sounds pretty darn good. Oh, and yeah, the controls seem a bit weird at first but since the unit is small, 20+ buttons simply won't fit on it so they've overload some of the buttons with more than one function which is not big deal after 10 minutes of acclimation. And then there's the remote. The first time I tried it didn't work either but just press the button a tiny bit firmer and it works fine. Lastly, if you plug this into cheapo speakers, it will sound crummy. Buy a $1000 receiver and plug it into a $99 dollar speakers, it'll sound lousy. So make sure your speakers match your sound expectations. The End

I purchased the "Sunbuck Wireless Bluetooth Stereo Amplifier System – 180W Dual Channel Sound Power Audio Receiver w/USB, SD Card, FM Radio for Home Speakers (25BU)" after reading reviews and finding the features ideal for my home installation. It has a very small footprint which is ideal where space is at a premium. Controls are simple and intuitive. Knobs for volume, bass, and treble operate smoothly and precisely. The remote works well, but its diminutive size will encourage getting lost. I find the connections and construction to be of surprising quality for such a value added amplifier. I drive two Wharfdale Crystal 10 bookshelf speakers, which it handles with ease. My inputs include a CD player and Bluetooth sourced from my phone. Sound quality and Bluetooth connectivity are excellent. It would be nice if the antenna was a post style rather than the wire style, as FM reception might be improved. Speaker connections are of the spring loaded variety and grasp wires securely. USB and SD inputs are nice although I have yet to utilize them. The unit is very attractive with a screen and volume illuminated by a neon blue hue. All in all, the amplifier is a very nice surprise and exceeds my expectations. I can't speak yet to longevity at this time, but hope it is of equal quality. I should mention that the Sunbuck and Pyle brands appear to be related, as the equipment is identical with the exception of branding. I would definitely purchase these products again in the future and recommend them without reservation.

It's a good product. Just make sure you use a 12V 5A power input. I tried it first using the AC cord on the unit and had a huge amount of 60hz speaker buzz that could be heard all over the house, it was bad. Plugged in my 12V DC power supply instead, no buzz, audio clear as a bell. That was my only issue. Other than that it's a good sounding little amp. I using it for Surround Rear channels on my Dolby 7.1 setup with a Denon amp. Great little amp for $40.

Excellent investment if you're the guy who needs tunes in shop and doesn't want silly wireless, must be recharged speakers. Hang up regular wired speaker's in your shop or garage. Buy this and you'll be set. Fm radio,or play tunes from phone via Bluetooth. The remote actually works and quite well. The cons: the blue screeb is extremely hard to see or read from more than a few feet away. The remote is extremely thin and cheap- be careful. Will this thing produce 180 watts...No way and not even close. I'd guess 40-50 watts and that's more than enough to power and few speakers in a shop. The unit itself- clearly cheap and built cheap. It's a set it and use when needed item. Will last a long time. Oddly you have a two power options. Power off on remote leaves volume light on. Power switch on back of unit shuts entire thing down. I tested this thing tonight as I was looking forward to it and it honestly met my expectations. I like it. As a bonus. I managed to walk about 40 feet away with phone in hand before Bluetooth connection dropped. Nice.
