Mifo O5 Gen 2 True Wireless Earbuds with 2600mAh Charging Case Bluetooth 5.2 Sport Wireless Headphones Noise Cancelling IPX7 Waterproof Wireless…

I didn’t really need a new pair of earphones but treated myself to MIFO O5 as a graduation present. Unfortunately, I wish I picked a different product. I find this pair of earphones very disappointing, especially considering the great reviews.

Packaging 4/5
Nice looking box, neatly packed content. The size of the box could easily be halved to save on resources and to reduce the space needed for storage.

Design 5/5
These look pretty neat in ear as the teardrop shape mimics the shape of the ear.

Sound 3/5
Mids and highs are very good but lack of truly deep bass spoils it. The deep thundering bass was promised but not delivered. My trusted old pair of Creative Outlier ONE I got for £20 is far superior and so is my wired pair of Sony MDR-XB50AP. In comparison the bass on MIFO O5 is flat and boring. Doesn’t pack a punch at all. I thought that maybe I was biased so connected the MIFO to the phone and Outlier to my tablet for comparison. MIFO sounded boring. So I swapped them out in case the device impacted the test. Same result. Changing ear tips didn’t help.
Maybe if there was an equalizer app available with the earphones it could make it a bit better.
Passive noise cancellation is good. You can barely hear anything around you.

Staying in ear 5/5
These feel like they’re practically glued in. They feel very secure in the ear. You can lift weights, run, jump, skip rope, they won’t budge.

Comfort 1/5
They are very light but get very uncomfortable after prolonged wearing. I used them for work Teams calls for a couple hours and my ears were on fire. The constant pressure on my Antitragus/ Antihelix (part of ear where the earphones secure against the earlobe and not the tip part you insert them in the ear) made the area red and sore for some time even after taking the earphones out. You can even see the redness in the photo taken after 60 minutes of use (indicated by blue arrows). You don’t really notice the pressure as it slowly builds up, but when you do notice, it’s too late. I think 60 minutes is the maximum length they can be worn for without pain.

Controls 1/5
As people mentioned before, the buttons are impossible to press whilst you’re wearing them without pushing them into your ear and rupturing your eardrum. If you actually want to press a button you have to take the earphone out. The earphones can be used separately but the button functionality is not there. You can only turn the volume up and skip to next song on one earphone and turn the volume down and go to previous song on the other.

Syncing 2/5
Bluetooth connectivity is good. There is a slight delay between taking the earphones out of the case and them connecting to a device but that’s not a big deal.
My problem is I’ve spent hours trying to get them to sync together after only using one for a while. They were just taking turns connecting one at a time regardless of them being both out of the case and reset process being followed. I got very frustrated because I realised that they wouldn’t sync once I arrived at the gym so had to pull out my trusted Outlier pair to save the day. Eventually, I managed to get them to sync but the frustration lingers.
There is no way to disconnect them from one paired device and connect to another without going to the device and turning the Bluetooth off or forgetting the earphones. So I found myself walking out of the house to loose my laptop connection and connect to my phone in order to avoid climbing up a flight of stairs, logging into the laptop and searching for the right setting to disable Bluetooth.

Case 3/5
The case is stylish and robust but it is very heavy. Not something you want to carry in your pocket all day when you don’t need a powerbank. Earphones magnetically click in for charging and stay secured inside the case properly. The case delivers a very long playtime and an opportunity to be used as a powerbank. If you want to use it as a powerbank you need to carry another small USB C to UCB adapter. It would have been useful for this to come with a small pouch which could hold the adapter and the charging cable. Think I’d lose the adapter on day 1 if I didn’t keep it in a box at home. There is no power indicator on the case either so no idea when it needs charging, especially if used as a power bank as well. Maybe there should be a version with a lighter case and shorter battery life to make it easier to carry around and more compact.

Warranty 4/5
1 year warranty is provided. Their website says that you need to register the warranty by filling in a form on the website when purchasing products from Registered retailers (Amazon). I tried to do that and was told by the customer support team that the warranty registration is automatic. So the lower rating is for the trouble I unnecessarily had to go through. Also some other brands offer 2 year warranty which is obviously better.

Overall rating 2/5
They are not completely terrible. If they didn’t hurt my ears and bass was better I would maybe even be willing to put up with all the other issues. I want to return them as they don’t deliver what I need from a pair of earphones.
However, these would be great for people who need their earphones to stay in place for their daily runs and don’t care for truly deep bass. They are not very good for prolonged wear but they might work for you if you want to run a marathon as you’re probably already used to full body pain so adding earlobes to the list of sore body parts won’t make much difference.

Yes, they come in a neat case. They look quite nice too, until you realise those two 1.5mm diameter spots on them are actually buttons – and unless there’s a magnifier handy there’s no chance of figuring out the symbols printed on them. It’s not as though their smallness makes them more attractive; they could easily be 2 or 3 times the size and still look fine. Plus, unless you’re a baby, your fingers will be too big to hook them out of the case easily – this is a prime example of style over function.

Then there was the pairing. After the first attempt with my phone (Samsung A5), when they worked, they refused to do so again. Maybe better instructions would have helped – who knows? – but I don’t have unlimited time, nor the inclination, to try to guess what needs to be done. Customer Services didn’t have any more luck than me, so I think that tells its own story.

Fortunately Amazon’s return process is brilliant, so back they go.

I received the Mifo O5 Gen 2 True Wireless Earbuds late 2022. Was easy to pair and set up and very impressed by the sound quality and the passive noise cancellation.

I regularly run with them and do not have any issues with them shifting or falling out, even though they are a solid build (read here a quality metal feel and weight)

I had an issue in March 2023 where the right earbud lost sound, I send the Mifo team a message and within 24 hours had a new pair dispatched with absolute minimal back and forth.

I will definitely recommend the product and the company – Thank you Mifo!

I was happy with everything. Except the mic. Its a disaster. Nobody could hear me. I heard the mic and it sounded like the person speaking, was in a different room. So disappointing. Gave them to my son and bought a sony earbuds instead.

These headphones do not move, once I found the best size earpiece they go in and don’t come out, they also seem quite comfortable (longest time I’ve worn them is about an hour and a half). Sound quality is good, they aren’t amazing, but for their use (sports headphones) they are probably the best I’ve owned.

Annoyances, they are minor; however, the touch control, whilst working as advertised, is really sensitive and the slightest you can activates it. My biggest personal annoyance is that the headphones don’t seem compatible with Garmin Fenix so it’s back to carrying my phone on a run.

Value for money though is excellent and I’m not disappointed.

At the price offered these are decent headphones worth the money you pay for.
Long battery life and good connectivity.
Not particularly comfortable to wear for long periods of time.
Biggest complaint is lack noise cancelling which I think was meant to be included in these earbuds.
Overall good but not great, would definitely spend a little more next time to get better quality.

As expected, had the previous version, so I knew what to expect. Stay well in ear and good sound quality and noise cancellation.
