Audioengine B2 Premium Bluetooth speaker review


Bluetooth speakers come in a variety of shapes, sizes and colors. They make them small enough to carry in your pocket or on your keychain and design them to snap on your bicycle handle bars or fit in your car’s cup holder. They even make Bluetooth speakers that can float in your swimming pool. All of these novelty speakers have their niche market, but when you want a Bluetooth speaker that looks nice enough for your living room while also providing exceptional sound quality, it’s tough to find one that isn’t made of black plastic with a thin sound that goes with it. Lucky for me, the folks at Audioengine have created what might be the nicest small Bluetooth speaker I’ve ever tried.

The word that came to my mind when I first unboxed the Audioengine B2 speaker was wow. This speaker looks very high end. The hand-built acoustically isolated wood cabinet looks like it has been carved from a solid block of wood. The B2 speaker is available in Walnut, Zebrawood and Black Ash. I was sent the Walnut version which has a beautiful grain and a smooth finish.

If you are familiar with Audioengine’s A2 speakers, the B2 looks like conjoined A2’s that have been positioned on their sides. The two slots in the center aren’t there for decoration, they are specially shaped bass ports, one for each speaker that provide surprisingly low clean bass.


On the back of the speaker you will find a volume knob, pairing button / status LED, Bluetooth antenna connector, aux input, AC power port and power switch. I was a little disappointed that the volume knob was located on the back of the speaker, but I got over it quickly. I like the clean lines of the front of the speaker. I think having switches and knobs on the front would spoil the look. Also, this is the type of speaker that you can plug in, turn on, and leave it that way. You don’t need to turn it off when you’re done listening to music because it has a special power saving “idle mode” which activates right after you stop playing music. I’d also like to note that this speaker does not come with an ugly bulky AC power brick. All you need is the included power cord and that’s all.


If you plan to stream music to the speaker from any distance, you’ll want to attach the included Bluetooth antenna. The funny thing is that I didn’t know it came with an antenna. I had been using it without one for a couple of weeks until I asked about it and then learned that it was in the same package as the instruction booklet which I hadn’t opened 🙂 I had been testing the speaker in a small room so I had not run into any issues with Bluetooth connectivity.


I like the look of the B2 speaker without the grill on the front.


But if you prefer the grill, it comes with one that has a grey knit fabric over a plastic frame. The cool part is that the grill is magnetic and easily snaps on or off the front of the speaker.

The Audioengine B2 speaker has two connection choices. You can connect a device using the auxiliary input jack on the back or more likely, you’ll pair the speaker with your computer, phone, tablet or other Bluetooth enabled audio device. I tested the B2 with my Macbook Pro and LG G3 smartphone. Pairing was simple for both devices. Basically you just turn on the speaker which puts it in pairing mode, go to your device and search for Bluetooth devices, click on Audioengine B2 when it shows up in the list and you’re done. No special software, access codes, etc.


I have been testing the B2 speaker for several weeks and I can’t find one thing about it that I don’t love. I like to stream music through Pandora and usually have the audio coming through my LG monitor. I hadn’t realized how mediocre the music sounded until I switched to the B2. Now I find that my music sounds so much better. Through this speaker music is full and rich with an excellent bass that isn’t too thumpy, but still easily fills a room. Dubstep fans may find the bass somewhat lacking, but I have no complaints. And at higher volume levels audio remains clean and clear. One of the reasons why this speaker sounds so good is that it uses aptX (along with other codecs) which is a high-quality Bluetooth audio codec.

Some of the songs that I listened to during my review testing:

Hold on – Tom Waits
Gary Jules – Mad World
Sam Smith – Stay With Me
Taylor Swift – Blank Space
Meghan Trainor – All About That Bass
The White Stripes – Seven Nation Army
From Eden – Hozier
Sweater Weather – The Neighbourhood
Ben Howard – Oats in the water

In addition to listening to music either streamed from Pandora or from my own MP3 library on my MacBook Pro, I also used the speaker while watching videos on my laptop. Bluetooth has a delay of about 30ms (milliseconds), but I did not notice any lag in audio while watching videos. Even videos that showed people taking directly to the camera did not have any problems that I could see.

Yes, you can find lower priced Bluetooth speakers for your home, but good luck find one that combines high-end looks with equally high-end sound quality. That is what makes the Audioengine B2 Premium Bluetooth speaker a real stunner. It impressed me and I happily recommend it.

  2. I love Audioengine products. I have a pair of A2 that I set up as my AirPlay speakers and use them for both my laptop and iOS devices for my big room. They work great with one exception and it has to do more with AirPlay: delay. When I play a video, the visual and sound is out of sync.

    This Bluetooth unit will solve that problem. My only concerns is the distance between the speakers: is it too close to provide good stereo seperation?

        1. Ultimately this is what it comes down to for most speakers. I’ve listened to some very expensive setups that just don’t sound “right” to me. they have the science behind it and the scopes to prove it, but it just doesn’t sound good/right to me. Don’t get me started on BOSE or Beats. I just don’t like them, others do. Beats to me sound distorted and all you hear is base. BOSE always sounds flat in the middle to me. But others swear by it. Buy what sounds good to you. My favorite headphones are still a $50 pair of AltecLansing earbuds.

  3. I got the Thodio iBox XC from my wife for my birthday last month, totally blown away by it, 200 watts, 51 hour battery, HD Bluetooth, o and did I mention it’s built out of 0.7” solid hard woods? Audioengine has something to work on…

  4. Upon opening the box I found that this was HIGH class! Everything was in their own microfiber bags – the speaker and the cables. The speaker is beautiful! I got the walnut finish. On close examination, it is double thick real walnut wood veneer, but they perfectly matched the color of any visible particle board. The speaker cover is nice, but obscures the beautiful front, so I took it off.

    It was very easy to pair, but I have to go into the Bluetooth menu on my iPhone 7 to select the speaker every time I want to play from my phone. The sound is very good. Clean enough midrange that I could easily hear lyrics of the music. Bass and treble are fairly good – my musical taste does not challenge them. To answer Meistervu’s question: the left and right are too close to allow me to hear the separation. I would have to transfer to my living room 5.1 sound system to get that. This B2 speaker is in my study. It’s a huge upgrade the sound system I had there before. Thanks Julie 😉
