  • Nice BT Amp
Color: Black2 ZK-502T
This little Bluetooth amp is awesome for a quick DIY audio project. It's super easy to set up and the sound quality is surprisingly good for the price. The Bluetooth 5.0 connection is solid and doesn't drop, and the separate treble and bass knobs let you dial in the sound you want. It's a fantastic little board for turning a pair of old speakers into a modern, wireless system. ... show more

  • Sounds great for what I wanted to build 🤘🏽
Color: Black2 ZK-502T
That's things crazy good. Easy to use and very sturdy. I was slamming 2 5.25" speakers and two tweeters lol. Awesome quality for price. Super fast shipping. Bluetooth works great. Connects fast. No need for app provided. Treble is super crisp I Made a mok-up cardboard box box lol before final wood design and sounds good. Even at 50 Watts its more then enough for what I need. Thank you ... show more

  • Great, but limited range
Color: Black2 ZK-502T
Great product for an excellent price, however, the Bluetooth range is only about 20 feet.

  • You had me at 21 bucks
Color: Black2 ZK-502T
Although this is a minimalists amp, other (fully clothed) amps with the same TPA3116D2 chip are 2 or 3 times this price. I bought the Rockville RockShelf Bookshelf Speakers 68B V2's and thought I would try driving those 6.5" bad-boys with this amp. I am amazed. I'm rockin Van Halen to the limits of my old ears and this little amp isn't even warm. HiFi has come a long way since I was a kid. This amp shipped 3 days early. I assembled the included parts in less than 5 mins. One of the images in the product description was helpful during assembly. I've been running this amp daily for two weeks with no issues. Bluetooth works great. Great sound and no noise. Great buy! However, keep in mind that this amp does not come with a power adapter which may cost an additional 20-30 bucks. Once you realize you've spent 40 or 50 bucks, you'll reconsider the "fully clothed" Fosi Audio BT10A for 50 bucks which has the same basic features, same audio chip, Bluetooth, etc., but with better speaker connections, a power adapter, a Bluetooth antenna and no assembly required. I'm no audiophile and I doubt I could hear a difference in sound quality, but the Fosi appears to be a more efficient way to spend 50 bucks. ... show more

  • Small yet powerful. Decent to run desktop speakers.
Color: Black2 ZK-502T
I need something very small for my desk that could put out at least 20 watts. This fit the bill perfectly! I mounted it under the shelf to keep it even more out of the way. Be advised, it did require a little assembly. You have to mount the heat sink, the top and bottom covers and knobs but they send a screwdriver. How handy. It connects to Bluetooth as a priority, then to the 1/8 input jack. So, if you want to use the jack, make sure you're not connected to Bluetooth. ... show more
