Capable little practice amp
A tidy little amp that tucks into a corner without upsetting the living room layout. It is a 20 W mini drum amplifier with a 6.5-inch woofer, a 2-inch tweeter, Bluetooth for streaming tracks, and a simple multimedia control knob. Three front knobs cover volume and tone, the indicator light is easy to see, and it arrives with an e-drum noise-reduction cable. At roughly 28.6 by 25 by 23.2 cm, it is light enough to carry from room to room without fuss. For practice it sounds punchy and clean, with a quick attack that suits pads and mesh heads. Bluetooth is handy for backing tracks, though the latency means I would not rely on it as a main monitor. The bass is respectable at sensible volumes, but a 6.5-inch driver in a compact box will not give you a chest-thumping kick. Push it and the top end can turn a touch sharp. At idle it is quiet, with no hum in my setup. Build quality is good for home use, it is genuinely portable, and the features feel well judged. Not a stage amp, but a solid, good-quality practice speaker that earns its keep.

Small and powerful!
My daughter loves it for her drums, it's really loud, not too big, and sound quality is good too. Value for money and easy to use, doesn't take up space.

Good sound and good quality
Good sound quality and good feel… easy to setup and easy to use. The cable is outdated- 6.25mm port is no longer available/used.

Very easy to use, very loud.
This is great. The set just came with headphones so I was stuck drumming to the pre loaded electronic rubbish which was boring. Now I can drum to the radio or anything I want. I found this easy to connect- literally plugged in the lead provided and that was all the installation needed. It’s loud enough to disturb your neighbours or you can put it on low. I love it! Makes my electric drums much more enjoyable as I can pretend it’s a real, independent drum kit.

Perfect size for my son’s drum kit. Good quality, had it a while and no issues.

Fine as a drum amp but Bluetooth is sub standard
As a drum amp is perfectly functional and sounds fine. The Bluetooth works but it’s in mono! You will only hear one side of a stereo recording so pretty much anything you listen to will sound weird. Buy this if you want a good, well priced drum amp but avoid if you want a Bluetooth speaker for music.

Fantastic
Fantastic compact useful Amp! I used this in my parents bungalow when I was visiting and it was perfect, could plug phones into it with my electric kit, but my parents loved hearing me play so they asked me to use the speaker every time I played, great sound quality, low noise, looks nice and a cool shape, good value for your money easy to use and great for small spaces and traveling! I just plugged my backing track in with my phone using the aux and played away

電子ドラム用のアンプがなく、ギター用のものを使ってましたが、これを使ったら音がすごく良くてびっくりしました。設置も簡単で軽いですし、操作もわかりやすく良いです。この値段でこの音なら大満足です。ただ、説明書の説明がちょっと荒っぽいというか、BlueTooth接続についてどうやったらいいか肝心なところが書いてなかったので星マイナス一つです。日本向けに説明部分は改善の余地があると思います。

⭐️⭐️⭐️⭐️⭐️ Excellent Sound, Build Quality & Value – Highly Recommended! I recently purchased the Coolmusic DM20 Bluetooth Personal Monitor Amplifier Speaker from coolmusic77 here on Amazon, and I couldn’t be happier with my decision. From the moment it arrived (very well-packaged and delivered quickly), I could tell this was a high-quality product. Sound Quality – The audio is crystal clear with a rich, balanced tone. Both the highs and lows come through beautifully, and the volume level is more than powerful enough for personal monitoring, small gigs, or home practice. Even at higher volumes, the sound remains clean without distortion. Bluetooth Connectivity – The Bluetooth feature works flawlessly. Pairing with my phone and other devices was instant and stable, with no interruptions. It makes practicing with backing tracks incredibly easy and fun. Build Quality & Design – The amplifier has a very solid, sturdy build that feels durable and reliable. Despite its robust construction, it is surprisingly compact and lightweight, making it very easy to carry around for rehearsals, small events, or practice sessions. Ease of Use – The controls are straightforward and intuitive. Even if you’re not very technical, you can get the perfect sound in just a few minutes. Value for Money – At this price point (€109.99), the performance and features you get are outstanding. Comparable products in the market often cost much more, but this one offers professional-level quality at an affordable price. Seller Experience – A big thank you to coolmusic77 for providing such a fantastic product. The communication, packaging, and delivery were all excellent, and I truly appreciate the reliability. Overall, the Coolmusic DM20 Bluetooth Personal Monitor Amplifier Speaker exceeded my expectations in every way. It’s perfect for musicians, singers, and anyone who needs a portable, powerful, and versatile amplifier. I 100% recommend this product and the seller coolmusic77. Definitely a 5-star purchase – I would buy again without hesitation
