We reviewed the A70 & A30 headphones from OneOdio last month and this time it’s the turn of the A11 Bluetooth headphones.

When one thinks of the A11 ‘SuperBass‘ it’s easy to instantly think of souped-up car systems on the road running from London to Norwich. On the contrary, however, it’s also the next unit on the review bench courtesy of OneOdio. Understandably, anything labelled Super Bass was always going to get our attention and we welcome the opportunity to put them through their paces.

A11 ‘Super Bass’ from OneOdio

How do the A11’s sound?

As it’s a Tuesday, and more specifically it’s “techno Tuesday” in the Attack office, we’re reviewing the A11′s listening by referencing techno. There are various similar qualities to the A70 & A30 from OneOdio which is most noticeable in the bass. The low end is rowdy, even before we look at the SuperEQ function that separates these units from their siblings.

The low-end has a significant range and is present. Despite this range, the super rumble in the low-end is not as defined as you’d hope. Overall, the low-end is flammy, and lacks the punch you’d hope for. This might not be as big a problem in other genres but for dance music, we found them lacking.

The high frequencies are not harsh and in fact are surprisingly wide for a closed-back pair of headphones. It’s the same with the mid-range frequencies – they are ok but nothing great. Both the mid and high frequencies are overwhelmed by the low-end.

What is the SuperEQ?

Hold down the SuperEQ and it’s going to get all the more hectic. The SuperEQ does not appear to have any other intention except for intensifying the sound of being in a club. Booming bass, cutting highs, much like the A70s from OneOdio. The trouble with overpowering bass, which might be great for gaming, is as a listening experience it’s not true enough. We preferred to listen without SuperEQ applied and you can think of SuperEQ as ‘SuperBass’..!

What’s in the box?


Inside the box is:

  • 1 x OneOdio wireless stereo headphones
  • 1 x Micro USB charging cable
  • 1 x 3.55mm audio cable
  • 1 x carrying bag
  • 1 x user guide

Comfort fit & durability

The comfort and durability are good. We tried walking, running as well as running upstairs. We’re hardly Usain Bolt so others might have put them through a more intense workout.

Although the sound does alter as they slightly move on your head, at the very least they stayed on and they possess a stronger clamp than you might expect. Therefore, they would work fine for running but possibly not a H.I.T workout.

The headband and earpads come in faux leather which is surprisingly soft and comfortable enough even after a couple of hours of listening. It’s worth noting the earpads only move up and down. If you have big ears, you may find it difficult to find a comfortable place for them on your head.

How good is the battery?

Battey life can be a cause for great debate, (looking at your Apple) and the A11 have a stated playback time of 24 hours.

This is great and compensates for the long charging time of 2.5 hours with the micro-USB cable (supplied). Of course, battery life is always misleading as the louder we play these the harder they will have to work.

Following a 2.5 hour charge, we spent a whole day listening to music for the review, as well as working on some new sample pack sounds. We found they kept going with no fuss and imultaneously we also were able to take calls on them (more on that below).

Bluetooth Including Multipoint

One thing we’ve missed so far is the Bluetooth functionality of the A11. The A11s use an SBC and AAC codec and are actually very reliable. We only tested them on Apple devices however but none the less it was a straightforward pairing process with no dropouts during use.

Noise Isolation

The noise isolation was excellent. Even at lower volumes none of the exterior noise bled into the cans. For the price, this was a particularly pleasing upside to the A11s.


One of the obvious competitors to the A11 is OneOdio’s very own A30. For just a little bit more spend you might prefer the overall experience. Others in the same space are the Samson SR850 at £28, the Aukey EP-N12 at £35 and Tribit QuietPlus 78 Active Noise Cancelling Headphones at £60
