The DSB-250BT is basically the most tantalizing in Denon’s Envaya series, but it’s a truly compact speaker that measures supreme over Eight-inches across. It adopts a acquainted sweet bar create ingredient, but the entrance-going by arrangement of drivers are tilted up somewhat for better sound dispersion. The stay caps are a rubberized field cloth (one stay has integrated controls), there are 4 nubby silicone toes, and on the help of the unit, a rubber walk hides a microUSB port and three.5mm AUX enter. Discrete, tiny white LEDs demonstrate the battery level. Denon makes exhaust of a striped cloth field cloth on the physique of the speaker, and this attire it up for a more top fee behold. My review unit changed into grey stripes on a dusky background, and there would possibly be also a dusky on dusky possibility.

The total enact is minimalist but upscale.

Music sounded unimaginable, with the bass and midrange, notably, being far stronger than other audio system on this size. I switched between the Envaya DSB-250BT and other audio system in my series in a identical size and price fluctuate, and it’s that low-stay efficiency that in actuality stood out. Most other audio system sounded tinny in comparability and these that had first fee bass serene sounded thinner due to they lack the decrease mid-fluctuate efficiency the Envaya DSB-250BT locations out. Even at high volumes it avoided distortion and didn’t bounce spherical, but when picked up whereas playing you would possibly well maybe be ready to in actuality feel the drivers and that colossal passive radiator pumping hard.

The Denon’s driver placement and processing also made the audio sound far more substantial than you would possibly well maybe maybe also ask.

And in case you function desire stereo, with a 2d unit Denon says you would possibly well maybe be ready to salvage elegant left and elegant channel stereo sound.

Water Resistance, Battery Life, and Buttons

Battery existence is rated at up to thirteen hours in preserving with life like volume.

A plump recharge took about three hours.

The Envaya DSB-250BT is rated as IP67 water and dirt-proof. That’s correct sufficient to dwell on 30 minutes in 3 toes of water. I examined it with a soaking within the sink and it survived to play once more. The one difficulty I noted that I haven’t lunge into with other transportable audio system is that the fabric veil absorbed water over time. So when it came out, there changed into noticeable distortion since the fabric retaining the audio system changed into waterlogged. After shaking it out for a short time and drying with a towel, the entirety changed into help to customary.

The membrane-model buttons abet watch over traditional good points only: volume (self sustaining from supply volume), energy, Bluetooth, and microphone. They’re the identical coloration because the stay caps, that will salvage them somewhat tough to see, and they also also require a supreme bit of power to rapid.

I’m in a position to also serene level to the Bluetooth 4.1 connectivity is declared to present up to ninety eight toes of fluctuate. I didn’t take a look at that upper limit, but it stayed connected whereas I wandered by arrangement of the dwelling and yard—most Bluetooth devices lunge into difficulty right here after I pass between ground, but the Denon speaker changed into accurate.


With an MSRP of $199, the Denon Envaya DSB-250BT isn’t exactly an impulse capture, but it’s much less costly than many top fee Bluetooth audio system. With its combination of audio nice (notably the strength of its low-stay efficiency), elegant create, battery existence, and portability, it’s a colossal decision for song followers that provides precise value for the money.
