The Denon Envaya DSB-250BT doesn’t have advanced features like multi-room, Wi-Fi or Alexa support, but it’s one of the best and biggest-sounding in its class. A Bluetooth speaker star.

The Denon Envaya is a satisfying, semi rugged and great-sounding speaker that balances fidelity and power like a pro. It's one of the very best you can buy at this size.

Works porfectly. Loud enough to be heard at party's. Attached string to add to bag while going to climbs. Good all round speaker.

Absolutely incredible sound and not just for the size. I ordered 2 as a stereo pair and to say they are impressive is an understatement. Stereo imaging singular is good but 2 together really shows how impressive these speakers really are.

After tons of research for reviews of this speaker, I decided to pull a trigger without a try because this speaker is not available in my country. TOTALLY WORTH IT! This is the best sounding bluetooth speaker for this size and price.

I would have liked to give these speakers 5 stars, they deserve that for the musical quality. The problem is that I bought them as a stereo pair to use with video, In the stereo paird mode they dont support aptX’s Low Latency functiont so you get the out of sync lip problem.

Quite amazing piece of kit

This is by far the most impressive portable speaker I've owned, even beating the much bigger Kicker iKick51 which I thought was the best I could find. For the size the sound is incredible, given that you turn the speaker volume on max and adjust the volume on your player.

This speaker gave reasonable sound and looked quite smart, but I had to return as virtually unusable. The control buttons are located on the side, covered by a very hard and stiff plastic end cap. This is part of the waterproofing of the unit.

Great sound under aux connection but sounds really broken under Bluetooth. My model definitely has issues. Poor quality control. Already returned

24 June 2018

Could not recommend this speaker enough. No bells and whistles will not answer you back. Just does exactly what you expect and the sound is so smooth. For me this was money well spent.
