MB Quart QUB Bluetooth speaker review

In the continuing expansion of the Bluetooth speaker market, I have noticed a few trends. There are those designed for personal, near-field listening. These boost the sound from your tablet or smartphone enough that you can hear it as a bubble around your person, but those further away hear it as tinny noise. Next, there are those at the far end, which mimic (or actually replace) large, party-space sized areas. You can sit one of these in the middle of a gym and control the sound for everyone. The ever-changing middle is where a lot of manufacturers are aiming, and there’s a grey area between the sweet spot of room-filling/low bass, and battery life/small footprint. The QUB from MB Quart aims to fit into this area. I have been testing it for a few weeks now, and am ready to share my results.

The QUB speaker is brick shaped at just over 6 inches on the long edge. The sides are slightly tapered toward the top, with the bottom being 2.5 inches and the top 2.25 inches over a height of 3 inches. The frame is a soft-finished plastic in a dark charcoal, and the grill is available in either bright red or a medium light blue. (Hey, I live near Duke and UNC Chapel Hill. We know our blues!) On the top are three buttons – two for volume and one that activates the speakerphone or the Bluetooth pairing. There is no button to control playback start/stop/pause or next/previous song through the speaker to your device. The front grill has a small logo in the center bottom. On the right side (to the right facing the front) on the lower side is a control panel with two ports (for input and charging) as well as the on/off switch. (You can connect via AUX cable if your device doesn’t have Bluetooth. There is a cable included.) There is also an access pin-hole to manually reset the unit.


The sound quality was surprisingly balanced for such a small unit. I set it on my family room counter paired with my iPad Air 2 while I read the news and ate breakfast this morning. Right now, Rachel Yamagata is singing “Stick Around” at a fairly loud volume – it’s really uncomfortable, even across the room – but the sound, instead of distorting, is delivering clear vocals and decent bass separation. Yes, I can tell it’s not a live performance, and there is more separation in the mix when listened to through headphones, but for sharing music with a room full of people, it’s perfect. Turned down to a comfortable level, I can hear each instrument in “How Old Are You, my Pretty Little Miss?” from Laurie Lewis and the Right Hands’ MerleFest recording. Guitar, fiddle, and banjo are balanced, and come to the fore without being overbearing during solo runs, just as the audio engineer mixed it. I also listened to several hours of podcasts last week, as I did some photography editing, caught up on personal email, and organized my workspace. I had the Quart on my desk, and paired with my iPad and video streaming through Downcast at 1.25X speed. Even with the slight speedup, speech was still clear.

Pairing was easy with my MacBook Pro, iPhone and iPad. It’s tough to change between devices with most Bluetooth devices, and this speaker is no different. If you have ever left one source on and tried to use your Bluetooth device on a different source, you’ll be well aware of this issue. Either you have to sleep or turn off Bluetooth on the actively paired device, or remove and re-establish connection with the second source. Some devices enable holding two or more devices and allow switching between them, but it’s not as common as I’d like.


There is the occasional lag issue with some devices. With my MacBookPro connected to a 23″ monitor playing an episode of “Miss Fisher’s Murder Mysteries” through Netflix, the voice and video would get out of sync, which really irritates me. This sometimes happens with hard-wired speakers, but it seemed to happen a bit more often with the Bluetooth. It’s not a big deal, unless you’re watching something that has a lot of action coordinated with background sounds. On a show like “Arrow”, I couldn’t bear it and plugged in the regular sound system, which instantly cleared up the lag.

The single largest drawback I found with the MB Quart is the charging plug. It is a wall wart with a hard-wired connection to a round adapter. The battery lasts a good while – it’s rated at 12 hours, and I was never able to run it down in a normal day – but why, oh why can’t manufacturers just use the standard microUSB, rather than the long-in-the-tooth coaxial one? Coax DC chargers can be a wide swath of sizes, voltages, and even polarity. Getting a replacement, or an additional one for a different location is difficult, at best. It really spoils a nice package.

The appearance is pleasing, and, while it’s not water-resistant, it’s not going to suffer from a mild spill, due to the four “feet” on the bottom that holds it off the surface. At $200 MSRP, it’s on par with similar units such as the Beats Pill, the Jambox (original), or other mid-range units.

  2. The reason Manufacturers sometimes do not use a Micro USB charger is the 5 Volt limitation.

    You can charge your device significantly faster if you make your own charger.

    Personally, I’d prefer slower charging to avoid having to travel with yet another adapter…

    are there any portable Bluetooth speakers that have a usb audio input and controls (basic) on unit speaker needs to be similar to bose soundlink mini

    I have only seen very low end, poor sounding Chinese speakers like that.

    Almost everybody seems to use Bluetooth (+ analog AUX input if you’re lucky).
    The USB is usually just for charging, sadly… Maybe Manufacturers don’t want to have to develop a USB audio driver?

    Also possible, that they found that using USB over Bluetooth saves hardly any power. Though it should be obvious that sound quality would be higher over USB without adding BT compression to already compressed audio files.
