🎧 Protective Headphone Bluetooth Amplifier by DAMGOO Review

Yes, it still has a 'voice' and is quite loud, but that doesn't bother me. I use this board to make fancy bluetooth speakers out of boxes, fridges, ammo cans, oatmeal cans, etc. Use a wide variety of speakers based on your needs.

Put 16V in this thing and it blew out. 12 volts is fine. Super loud startup sound and Bluetooth connection sound. Just wondering why it says it can handle 25V power, I bet it will explode if you plug in 25. I did 16.4v and popped and started smoking. Worked fine on 12 volts until I wanted more power. Works fine if only 12 volts.

First of all I would like to say that this product is not intended for music lovers but sounds great for the price and works as advertised. I bought this for one of my students who was working on a project. They liked it, I told him how it works. I took an old laptop charger and asked them to upgrade it for the power bank and it was great. Remember, the more power you give this baby, the better the sound quality. But that doesn't mean you have to put a ton of power on it, you have to put the…

Love this little Bluetooth application suite. Provides good power to speakers and is a great component for BT speaker assembly. But I've found that the line-in feature requires me to unplug and plug the line back in when I turn off the device. This is problematic as I mount them in cases and have extensions that attach to the outside of the case. BOOOO Damgu. Otherwise a good amp. I specifically chose it to add a line in feature for my clients and it was a deal breaker.

Fun little amp, surprisingly loud and sounds really good considering it's around $15! Really amazed. I connected it to 2 ceiling speakers, 1 in a small office and an adjacent bathroom. Play music from a Mac with Airfoil via AirPlay to an older AppleTV hardwired to the headphone in/out jack on this baby booster. It's in a soap dish on the wall behind my attic door. No crazy lady yells at you on startup, but she says "LINE IN!" when switching from Bluetooth to line input. I laugh every time and…

It does what it promises. The sound is crystal clear and loud enough to be heard outside on our deck with two Yamaha 8 ohm speakers on a busy street. I connect to the block via bluetooth from the phone. So far it has connected every time since the first pairing with no problems. I turn off the device when not in use. When turned on it first beeps to say it's on and the second time it connects to the bluetooth. I didn't try to turn the sound up as high as possible as I'm sure my neighbors…

It works great replacing my amp for my Fender Frontman 15r that died a long time ago. I installed an 8 inch Celestion speaker last week and it sounds great. I'm going to buy a second speaker and assemble a box from the same six as the Fender box, run speaker wire there and unplug both amps since I'm only using half of them. If I had money I would do all sorts of audio projects with it. I love this small but powerful amp that works perfectly as a Bluetooth for my computer and as an amp for my…

Just hooked up to my homemade speaker box which runs on 12 volts and 2 amps. The overall connectivity options on this board are really great! Two audio inputs! BT and AUX cable, two power inputs, DC jack or power jack with standard screw terminals. Only these two things are hard to find on the board, and even more so in this price range. SOUND QUALITY: Generally acceptable. Obvious noise at high and low levels. You can only hear it when you are very close to the device. I'll know if it's my PSU

My wife wanted speakers around the pool so the soundbar wasn't so loud to hear music in the back of the pool. So I bought a set of wired outdoor speakers https://www.amazon.com/gp/product/B002C775W0/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1, unscrewed the bottom and used it as a waterproof case for this module. . I then bought an AC-DC converter: https://www.amazon.com/gp/product/B08B3T9DX4/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 and hooked up AC power from my landscape…
