OneOdio Fusion A70 review

Any links to online stores should be assumed to be affiliates. The company or PR agency provides all or most review samples. They have no control over my content, and I provide my honest opinion.

Last week I reviewed the OneOdio A30, which I found to be superb all affordable headphones with half-decent active noise cancelling thrown in.

Today I have the OneOdio A70, which are even more affordable, which are £39.99 on Amazon but with a 15% off voucher taking them down to £33.99. Or, available directly from OneOdio for £28.80 using the code HAPPY20 at checkout.

Design & Fit


The one unique feature of these headphones is the option for either a 3.5mm input or 6.5mm. The only benefit of this I am aware of is allowing people to daisy chain headphones together, allowing them to listen to content from the same source. This could be handy in some scenarios, it would be great on flights or train journeys when my and my partner both want to watch something on a tablet/laptop.

I am not entirely sure why they used 6.5mm, though. From a brief bit of research, there is no functional difference between 3.5mm and 6.5 performance nowadays, and the cable they included is 3.5mm to 6.5mm so you are still plugging into a 3.5mm source. The included cable seems to be so you can plug music instruments in from 6.5mm to the 3.5mm cable.

The headphones themselves are the usual all plastic build with uPVC coated earpads. They look good as far as affordable headphones go, and there are plenty of adjustments to make them comfy.

The earpads just about fit over my large ears, maybe a little on them. I find I get hot ears within an hour, which is standard for this design of headphone.

Sound Quality

OneOdio advertises these as having extra bass sound and that they are designed for DJs and bass enthusiasts alike.

That is probably an accurate description. Audiophiles or anyone wanting to listen to things analytically should avoid these, but I imagine the regular public will enjoy the sound.

They are very bass-heavy, with the bass emphasis extending into the mid-range, which can negatively affect vocals and the clarity of mids.

There is a slight uplift in the treble, giving an overall V-shaped sound, but this is only slightly uplifted, so it doesn’t end up sound too harsh.

Overall, mids suffer quite a lot due to the bass bleed, but if you enjoy bass-heavy music, these can be fun to listen to.


These claim to offer 50 hours battery, which is just mind-boggling. I haven’t used them for anywhere near this long so I can’t confirm the exact battery life, but they show no signs of dying after several hours of use. This battery life will make them a good option for keeping in your travel bag and rarely having to worry about charging them when on the move.

Price and Alternative Options

The OneOdio A70 are £39.99 on Amazon but with a 15% off voucher taking them down to £33.99. Or, available directly from OneOdio for £28.80 using the code HAPPY20 at checkout.

At this end of the market, it is difficult to pick out decent alternative options. Amazon is saturated with affordable brands. OneOdio compete with themselves, I can see at least 7 different models, all within £10 of each other.

If we look at Amazon reviews, unreliable as they are, OneOdio appears to be the best bet at this price point. I personally prefer the slightly more expensive OneOdio A30


The OneOdio Fusion A70 headphones are good affordable headphones. My initial impressions were that they are excessively bassy, but it is not quite as bad as I originally thought.

Due to the heavy bass, you need to specifically want this sound profile if you buy these. I think most people will like them, mainly regular buyers wanting affordable headphones, not audiophiles.

Overall, as long as you want a bassy pair of headphones, for the price, these are good.
