Review: TOZO Earbuds - Excellent Choice! - These open-ear design TOZO O2 earbuds work great for me - they were exactly what I was looking for! If you like open-ear functionality, both horizontal and vertical adjustments for the optimum ear fit, very good sound, and excellent software that enables quick pairing and the earbuds to work seamlessly so you can just put them on and listen to audio, these earbuds are a great choice! I did have an issue with the original pair, and customer service handled everything promptly and professionally, even sending another pair of earbuds that work just fine (Thank You, Winona!). I would buy from TOZO again without hesitation - they make great products at a reasonable price, and have excellent customer service! I'm very impressed!
Review: Another TOZO earbud, another fantastic offering. - TOZO has recently gotten into a big trend of releasing these open ear style headphones and while none of them will replace normal in ear earbuds or full over ear headphones in BASS offering, the audio they do deliver really is fantastic given the design limitations while offering the open ear freedom and comfort. The TOZO OpenEarRing buds have been my favorite for a while now. Offering a very unique sort of clip on method and comfort while being really good sounding while I do various household activities. In comes the new O2's and I have to say, these may be my new favorite choice, if anything, a set I plan to use a lot alongside the OpenEarRing's. Audio quality is very good to my untrained ear, the fit over the ear with this new hook style actually feels really comfortable and stable when moving around, and has the added benefit of having a range of adjustment with a clickety hinge that has a pretty good range in it as seen in the pictures. Once you put these things on, they stay in place pretty good and the hinge allows you to adjust the way they position in your ear to optimize the sound going into your ear hole which isn't something you get quite as well from un-adjustable offerings that you have to sort of move into place, and hope they stay. These ones hook on your ear until you are happy and they sit nicely, then you can then adjust the bud itself optimally which then both seem to stay in place really well. It's a unique but very effective design which I really like personally. Like usual, the buds are Bluetooth and seem to have reasonably good range and signal with the latest BT 5.3. It is possible to get them to have a little trouble if you move in a way that blocks your phone from the line of site to the buds and mess with the signal, but it's a lot less of a problem than it was on some of the older bud designs. Battey life seems about on par for the size and design, with charging speed of the buds being reasonably quick to get a few hours of charge with only a few minutes of time spent in the charging case. The case itself is a neat design that's flatter and wider than previous bud designs that go for that taller shape which is just different but still easily pocketable and portable. Possibly it would have been nice if the case was wirelessly chargeable like some older offerings like the T10's since the case size lends to being perfect for that, but it's USB-C and charges perfectly fine by itself and holds a bunch of charge to charge the Buds with while out and about. The buds are also like all of TOZO's more recent offerings, able to connect to the TOZO app on your phone, be adjusted within the app even to change the control methods for both sides to whatever you want, and push FW Updates to the buds to improve them as TOZO releases updates and fixes. (Which has helped a lot of their older designs that have ANC which improved a lot from an earlier to later FW version). Overall like most TOZO offerings, their headphone/earbud offerings continue to be extremely good value for money. I like to keep up on each model they release as I use headphone nearly constantly in my life for both Music, Entertainment, and Work and they area fantastic offering for all of that with options galore you can afford to buy multiple of for the price of one "Premium" model from other Brands. Maybe some of those brands can justify that price in some way shape or form, but for the most part, TOZO really gets within an arms throw for such a better price that it makes the jump hard to justify in my own experience. TLDR : If you are in the market for a set of fantastic open ear buds and want a pair that can fit pretty much any ear and sound great doing it, give these a try. Solidly Recommend.

### ⭐⭐⭐⭐⭐ Great choice for over the ear with great sound for the price and robust to survive elements.
*by B***G on October 12, 2025*

This is my second pair to give as a gift. My original one I purchased over a year ago works great with my iphone. I love the sound and comfort. Fit and comfort: Its over the ear without inserting them into the ear. On average I wear these 4-6 hours at work five days a week. I have yet to use them during a workout but is water resistant. Battery life: For the useage, I charge them about 2-3 times a week. It lasts all day for me and only died when I forgot to charge them when the case was flashing orange. Sound: For over the ear, it has very good clear audio and bass. The app can adjust the sound for music or talk radio. Connectivity: For the most part, it connects to my phone and ipad seamlessly. However, there were a handful of times it didn't connect or the sound touch controls didn't work. After deleting the device from Bluetooth on my iphone and reconnecting them, it fixed it. It doesn't happen enough for it to be a big hassle. I actually lost the right ear bud in the parking at work. Somehow I found it a week later with surface scratch and scuffs on the charging and listening side. I wiped it a bit and stuck it into the charging case hoping it still works. To my surprise it works like it did day one. After that I had to write a review.
