After using the TOZO O2 Open Ear Wireless Headphones, I can confidently say they’re a solid choice for anyone looking for comfortable, versatile earbuds.
Pros:
Comfort: The open-ear design is incredibly comfortable, even for extended wear. No more ear fatigue! Adjustable fit: The dual-axis rotation allows for a customized, secure fit. Sound quality: Surprisingly good for open-ear design, with clear audio and decent bass. Awareness: You can still hear your surroundings, great for outdoor activities or office use. Call quality: The noise cancellation for calls works well, making conversations clear. Battery life: Up to 42 hours with the charging case is impressive. Dual device connectivity: Handy for switching between phone and laptop.
Cons:
Sound leakage: At higher volumes, others nearby might hear your audio. Volume floor: The lowest setting might still be too loud for some users. Case size: Slightly bulkier than some in-ear models’ cases. No wireless charging: The case charges via USB-C only.
Overall thoughts: The TOZO O2 headphones have become my go-to for daily use. They strike an excellent balance between audio quality and environmental awareness. The comfort level is top-notch – I often forget I’m wearing them. The sound quality exceeded my expectations for open-ear buds. While audiophiles might notice some limitations, for most users, the audio is clear and enjoyable. The effective call noise cancellation is a big plus for work-from-home situations. The main drawback is the sound leakage at higher volumes, which might be an issue in quiet environments. Also, while the battery life is good, the lack of wireless charging for the case feels like a missed opportunity. In conclusion, if you’re looking for comfortable earbuds that don’t isolate you from your surroundings, the TOZO O2 is an excellent choice. They’re particularly well-suited for outdoor activities, office work, or anyone who finds traditional in-ear buds uncomfortable. Despite a few minor drawbacks, they offer great value for money and have become an essential part of my daily routine.

Wady: jak na razie nie znalazłem żadnych!

When I came across these, they seemed like the perfect solution for me, and they honestly exceeded expectations.
In-ear headphones never seemed to fit properly for me. The ones without an ear hook would quickly fall out, and for those with one, the angle never seemed quite right to hold well. These are adjustable, so they fit well and hold more securely than any other earphones I’ve ever owned. They’re also small enough to be able to take out with you, a benefit that over-ear headphones never had. While more comfortable than in-ear ones, over-ear ones also seemed to get uncomfortable after a couple hours. These seem to be the most comfortable earphones I’ve ever owned, and I could easily wear them the whole day without issue. I hate being heard and pretty much always use my devices on mute, so having headphones that can be worn all day is a huge help as music helps my mood a lot.
They can also be worn with glasses without issues, so thats a pretty big plus.
Wearing in-ear ones, I would always worry about them potentially causing damage and effecting my hearing overtime. They always seemed to need cleaning after every use as well, which was a bit annoying. However, these don’t go in your ear, so I’m not constantly worried about having them on and can wear them for longer.
They are touch operated, which means I can use the back of my hand or wrist to operate them instead. This probably doesn’t matter much for most people, but my hands sweat pretty excessively which can end up damaging things. Usually I would just avoid touching them after putting them on, but these are extremely easy to operate while also not requiring proper contact. I have managed to accidentally pause them a few times, but it’s just a matter of getting used to them. Luckily, they aren’t too sensitive, so they don’t get paused by hair.
I can’t comment much on the sound quality, I’m not an expert on the technical side of things, but they definitely don’t sound bad. I do wish it was possible to lower the volume a little more though. While loud music is okay at times, sometimes you only want it on quietly, but even the lowest volume seems quite loud on these. Perhaps thats just me, as I’ve always been more sensitive with sounds. They do seem to leak sound more than other headphones I’ve used, perhaps due to the open design, but they’re fine on the lowest volume and I honestly wouldn’t want them any louder most of the time.
It’s possible to only have one on at a time, which is nice as it’s easier to stay aware of your surroundings that way. They aren’t too noticeable if your hair is long enough to cover them, at least using the black ones with a darker hair colour anyway, which is also a plus as I’d be too self-conscious to wear them around people otherwise. They also come with a warranty, but you do have to sign up for it within 14 days.

I’ve been using TOZO earbuds for several years now, and they’ve consistently impressed me with their quality and performance. However, like many people, I’ve never been fully comfortable with in-ear buds for long listening sessions. That’s why I was especially excited to try the TOZO O2 True Open Ear Wireless Earbuds : and they’ve completely exceeded my expectations.
These are truly lightweight and incredibly comfortable. In fact, it’s easy to forget you’re even wearing them. The open-ear design solves the comfort issue I’ve always had with traditional earbuds, making them perfect for long-term use without any irritation or pressure.
The sound quality is fantastic; clear, rich, and surprisingly immersive for an open-ear design. Pairing was quick and seamless, just like with other TOZO products I’ve owned. My whole family uses TOZO gear — my kids, my wife, and myself and we’ve never been disappointed. The O2s continue that tradition of reliability and innovation.
One small suggestion: my previous in-ear TOZO buds had a charging case with multiple lights to show the battery level. With the O2, there’s only a single light that indicates when the case is fully charged, but it doesn’t show the current charge level. It’s a minor thing, but having that feature would be helpful.
I chose the grey color, and I’m glad I did because it blends well with my typical clothing and looks sleek and understated.
All in all, this is another excellent product from TOZO. If you’re looking for a pair of wireless earbuds that are comfortable, sound great, and let your ears breathe, the TOZO O2 is a fantastic choice. Highly recommended.

I tried an open ear wireless earbud from another brand before. Because I couldn’t use it with my glasses, I immediately returned it.
But I still wanted to have one because open ear product is more comfortable for ears in general if I need to listen to music for a long time while I still need to hear my surroundings.
This product satisfies all of them. It is comfortable even with my glasses, the outside sound is still audible and the sound quality is very good considering the price.
Why is it comfortable? It is because the ear holder(?) is very flexible and can be bent in many ways.
I would recommend this to anyone who needs to wear glasses and wants to have a good sound quality.

the TOZO Open Buds: I’ve found them to be a solid choice for open-ear earbuds. The sound quality is impressive, especially considering their design. The 14.2mm dynamic drivers deliver clear mids and highs, and the bass has a satisfying punch—more so than I expected from this style. I actually prefer their sound and bass over the 1MORE S50, which I also own.
Battery life is another strong point. I’ve been getting close to the advertised 12 hours on a single charge, and the case provides additional charges, totaling around 42 hours. This means I can go several days without needing to recharge, which is incredibly convenient.
The fit is comfortable and secure, thanks to the adjustable ear hooks. They stay in place during workouts and long listening sessions. However, one minor inconvenience is that you need to reposition the ear hooks to their original position before placing the earbuds back into the charging case. It’s a small hassle, but worth noting.
Overall, the TOZO Open Buds offer impressive sound quality and battery life for open-ear earbuds, with just a small design quirk to consider.
