Douni (A7) 20W Portable Bluetooth Wireless Stereo Speaker with Enhanced Bass, LED Button Backlighting,Support Handsfree Calling, NFC

I purchased this speaker after first learning about it from an online video review by clavinetjunkie. I have been tinkering with electronics and Hi-Fi gear for nearly 50-years, and have not been impressed with most Bluetooth speakers. The Bose SoundLink Mini and Mini II were not without flaws, but they raised the bar significantly a few years ago. Unfortunately, like most Bose products, they were overpriced in my opinion. Since then the market has been flooded with Bluetooth speakers - some good, some not - and prices have come down. The biggest acoustic challenges for small speaker engineers are 1) creating a sound stage that is as wide as possible, 2) obtaining an appropriate level of bass, and 3) tuning what you've got so it doesn't sound "boxy." I still don't know much about who Douni the company is, but I think they hit a home run with this speaker, and recommend it without reservation. I recently received a Bose SoundLink Color II as a Christmas gift from my employer. It's OK, but I honestly wouldn't spend my own money on it. It costs twice as much as the Douni A7, but in comparison the sound stage is narrow and the deep bass level is lacking.

I am very pleased with this bluetooth speaker. Here is how I assess it:Cons:- No battery charge-level indicator. "On" light which blinks on and off blue during operation but changes to blinking blue and red just before battery is totally discharged.- No volume indicator- No ability to pair with second speaker for stereo modePros:- Speaker sounds great! Bass is strong but not distorted at low volume. Treble is clean, distinct, and smooth. With phone set at max volume, I only turn up speaker volume 4 "clicks" from off for good background listening in a 12' x 12' room. Volume level continues up to at least 50 "clicks". I can't imagine a noisy enough environment that would require playing the speaker anywhere near half volume or higher.- Bluetooth pairing with my Samsung phone is easy and after pairing, is automatic when speaker is turned on.- Bluetooth range is at least 55 feet and through 2 interior walls. I did not determine its limit.- At background playing volume, I can hear background amplifier hiss when music is paused. However, to hear it, I have to put my ear right next to the speaker. There seems to be a circuit in the speaker which detects the pause in music and within about 2 seconds, turns the amplifier gain down so the hiss becomes inaudible. This happens in both bluetooth and aux-input mode. So for my speaker, background hiss is no issue at all.- Battery charging time from complete discharge seems to be about 4 hours using my phone AC charger.- Control buttons light up in dim light when my hand comes near the top of the speaker: a nice design feature. The buttons have a nice audible and tactile click when pushed.- All battery-operated speakers will eventually not take a charge once the battery fails. Douni states that this speaker does not have replaceable batteries. However, in contrast to some speakers that require difficult disassembly, this speaker seems fairly straight-forward to repair. The rear speaker grill can be removed by carefully prying it off with a thin pry tool which reveals a rear inner panel which is easily removed with screws. That uncovers the entire rear of the speaker including the two 2200 mAh batteries. New batteries of this size are readily available on Amazon. Google "Douni A7 disassembly" to see a video which shows the batteries.

At one third the price, eats the soundlink mini 2 for breakfast.. Sounds fuller at any volume and can go a notch or two higher almost without losing its composure.. (the soundlink mini 2 is known to distort very badly at high volumes)Could even be the best under $100 because of the versatilityIndoors or outdoors, low level, ambient listening or parties(capable of filling a small living room)Thank you Douni for the great features at a bargain price.. and @clavinetjunkie for close to perfect tuning..

Was hoping for a really nice speaker given all the positive reviews but I walked away pretty disappointed. I noticed a small hiss of noise at a pretty constant level in bluetooth but figured I could live with that. However, when using any AUX source, that hiss became WAY louder and also accompanied a high pitched whine. I feel like maybe this speaker is upping the gain on sources and processing them in a way that's adding a bunch of white noise and compression like artifacts. It's a shame since I was expecting better. Also, anyone wanting to use this as a bluetooth speaker on a TV, there's just enough lag in the signal to make it unusable. You would need to use AUX and possibly deal with the same issues I listed above.

I am quite astonished how this speaker system sounds. I spent hours researching stereo bluetooth speakers in this category and decided to try this unit. It has a well rounded sound. Lots of bass. Good mids and no screeching highs. Lots of power.The bass won't shake the room but for the size of the unit it does extremely well. You will wonder how such a small speaker systems sounds like it does.Pairs easyCharge lasts a long time considering the power output.Hands free calls with built-in mic.Make sure you order an adapter for the included USB cable unless you have a spare hanging around..
