Far Better Than Expected
I’ve been using these headphones for a while and they’ve turned out better than I expected. The open-ear design is comfortable and avoids the pressure you get with in-ear buds. The adjustable hooks make them secure without being awkward, and once you’ve worn them a couple of times they just slot into place naturally. Sound quality is solid. Vocals are clear, bass is present without being muddy, and they work well for both music and podcasts. They don’t block out background noise completely, but that’s part of the design. It’s actually useful when running or working in shared spaces because you stay aware of what’s going on around you. Battery life is strong. A short charge gives hours of use, and the case display makes it easy to keep track of power levels. They last through a full day without issue, and the quick-charge feature is genuinely handy when you’re about to head out. Build quality feels good. They’re lightweight but sturdy enough for daily use. The app integration adds flexibility with EQ settings, which is nice if you want to fine-tune things. Overall, they balance comfort, practicality, and performance. They’re not trying to be premium studio gear, but for everyday use they’re excellent value. I’d recommend them to anyone who wants headphones that don’t dig into your ears, stay put during exercise, and deliver clear, balanced sound without breaking the bank.

Brilliant earphones.
These openear headphones are my first dip into this style. Whilst I will be using my TOZO NC3 as a reference point, this is not a companion review. I use headphones daily for the gym and am always looking for the perfect set. I was apprehensive on both sound quality and fit of these, not because of the brand but more so the design. I have worn these for some weeks now and put them through their paces in the gym. I initially found them fiddly to put on and get into the right position, mainly due to the more simple design I’ve been used to. However, after a couple of uses, it soon became second nature and now they just seem to slot into place. The sound quality is excellent and paired with the app, you can set your own preferences. I was surprised as to how clear they are especially given that they are not like the more traditional earbuds with silicone tips. They are not designed to, nor do they cancel out other noises. However, once these are positioned correctly, ambient and background noise is just that. You can concentrate on your music whilst still knowing what’s going on around you. These have not fallen out or moved during any workout and the functions are easily operated even with sweaty fingers. Having a slightly bigger surface area helps with this. Another benefit is no stress or irritation in your ear. I am sure this is also healthy and more gentle on hearing Battery life is very good and with the clear display on the case, you should be able to monitor when these need charging. You also get a nice little repeated noise in your ear once the charge is too low. Connection to Bluetooth was easy and worked first time. For me, it still comes down to what type of workout I’m doing, whether there’s any classes and excess music in the background as to which ones I wear. I always keep both in my bag so I have a choice. Another good choice.

Very good quality
These are very good. Battery charge lasts a while, even when they've not been used for ages. Sound quality is very good. Just a little bit annoying when they slip out of your earhole, as this will make one of the buds turn off.

Amazing comfort and stellar sound
Got these mainly for comfort, and they absolutely deliver. I can wear them all day without even noticing, and they stay put no matter what I’m doing—no constant adjusting. The sound really impressed me too. Even though they don’t sit in your ear, the highs and mids are super clear, and there's decent bass. Not on par with in-ear buds, but way more comfortable. I also love that I can still hear what’s going on around me—perfect for the office when I don’t want to keep pausing music to chat. Battery life has been great so far. Been using them daily for a week and still haven’t had to recharge. The case is small and pocket-friendly too. Overall, super happy. If you care about comfort and want good sound at a fair price, these are a great pick.

Excellent open earphones - perfect for running
I bought these to use whilst running, and I'm pleased that they are perfect for that. The loops swivel sideways and up and down so you can get a really snug fit with the 'earphone' part tucked next to the opening of your ear. It doesn't move or fall off when running! The sound quality is also great but you can still hear noise from cars/people etc around you. Comes in a thin case, took seconds to pair and worked straight away. The battery percentage indicator on the case is a nice touch. Would recommend!

TOZO OpenWear Earbuds
I’ve been using the TOZO earbuds for a while now and I’m genuinely impressed with what they deliver for the price. The sound quality is surprisingly rich — clear vocals, solid bass, and a nice overall balance that works well for music and podcasts alike. They’re also really comfortable to wear, even for long stretches, thanks to the lightweight design and soft ear hooks. Battery life has been strong, easily lasting me through a full day with the charging case providing plenty of top-ups. The noise cancellation isn’t perfect, but it takes the edge off background sounds enough for everyday use. Calls are clear indoors, though they can pick up a bit of background noise outside. Overall, they feel like a great mix of comfort, performance, and value — I’d happily recommend them to anyone wanting reliable everyday earbuds without paying premium prices.

True Comfort and Impressive Sound – A Game-Changer for Open-Ear Earbuds
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.

Beyond my expectations!!
I have some somewhat expensive, great quality earbuds that I use the majority of the time. I needed a backup pair to use occasionally and for when family needs some (to keep their ear wax off mine! Lol). Because of their low price and the decent looking features, I gave these a try. My expectations were not too high but to my surprise, when I first used them, the sound quality was on par with my other earbuds. And the noise cancellation was surprisingly good. Also appreciative of the clear voice quality when on calls. I still prefer the others for my regular personal use, but these are an exceptional second pair!
