The case lets these headphones down the most. Don’t get me wrong, the metal coating is a nice touch, if it does add a large amount of weight to the overall product, but it’s the latch on the lid. It’s very flimsy, which is strange because it seems like the rest of the case has had a decent manufacuring quality put into it.

The case as you all know by now acts as the charger for the wireless earbuds. But this time round, we’re looking at a whopping 100 hour battery life! That’s insane. And with a max play time of around seven hours on the earbuds, it means that the case will charge your earbuds up to 15 times over, ot near abouts. Easily the most impressive we’ve seen in a set of wireless earbuds to date. Oh, and they use USB Type-C to charge! Hallelujah!

The Mifo earbuds themselves are very small, and shaped like a teardrop. A decent size, and smaller than a set of Airpod 2nd generation earbuds. They’re coated in plastic, although coloured the same as the metal case. It was definitely a decision to keep the weight down, which I’m all for.

There are four buttons, two on earbud. These are used to control volume of your music and to take and hang up calls. A nice feature is their Transparency Mode, which allows ambient sounds to enter the headphones, making them especially safe when wearing in a busy city like London for example.

The worst thing though about the earbuds are the size of the buttons. They’re tiny. and very hard to press. I had to literally use a fingernail to carefully press each button. It was a lot quicker, and a lot more accurate to just pull my phone out of my pocket to adjust volume and answer calls.

Initial connection to the Mifo buds was seamless. They were recognised under my Bluetooth tab on my phone, and now every time I remove them from their charging case, they’re recognised and connect straight away within seconds.

It’s no secret by now if you keep up with our headphone reviews, and the same was here. I opted for the largest earbuds provided, which offered me personally the best noise isolation and seal to really feel that thudding bass come through. There are a decent number of sizes available to you, so have an experiment.

In terms of sound, these are one of the better. Of course, wireless earbuds still have a journey to go if they want to catch up with the more conventional over-ear headphones, but they’re getting there. The Mifo O5 sports buds recreate pretty decent detail in their headphones. Clarity in the treble frequencies is very nice, enabling vocals to shine above the lower bass tones.

Mid-range tones do I must admit get a little lost, as the bass can be quite overpowering at times. This is caused by the seal the buds create with your earlobes. Personally, a decent thud in my music makes me feel as if the music is coming alive, so I’m all for it, but here you have to sacrifice of some detail in the mids.

Billy Eilish’s vocal tones in ‘Bad Guy’ are clear and sound smooth, while the bass centric backing track keeps everything sounding full. However, if you turn to something like Fatboy Slim’s ‘Weapon Of Choice’ the bass is a little overpowering that the rest of the instruments get a little drowned out but not overpowering. It’s a decent enough sound, and one that’ll satisfy a music enthusiast if they’re looking for a decent set of wireless earbuds to travel with.

The Mifo O5 wireless earbuds aren’t perfect, but they come pretty damn close. For the price they sound absolutely superb, and with that 100 hour recharge battery, they absolutely smash most of the competition that we’ve seen at TechNuovo. I would have liked to have seen a better quality seal on the case, and some bigger more tactile buttons on the sides. Oh, and maybe some more detail in the mid-tones but that’s being picky at this point. For more information, you can head over to the Mifo O5 website.
