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.
Review: very good quality at an excellent price. - I was at first looking for a pair of small over the ear traditional headphones for my wife. She cannot find ear buds that are comfortable ( very small ear canal), and her full size Sony headphones are just too cumbersome in some situations. In my research I found the TOZO O2 open-ear headphones. They reminded me of the over- the- ear hooked headset we used for our cell phones many years ago. The TOZO O2 appeared to be the perfect fit for her problem, something that could go over her ear without messing up her hair or making it uncomfortable to wear a hat outdoors. After about two weeks of using them she is absolutely in love with them. She uses them around the house, when she is out walking, or working in the garden. They are lightweight and she says that she doesn't even realize she is wearing them sometimes. I am especially happy that when she wears them while walking around the neighborhood she can still hear cars , kids on bikes , or just the neighbors saying hello. I have used them a few times and for my needs they are worth twice the price. The sound is crisp and clear with good bass that's not overwhelming and great mid tones for listening to music or podcasts. The TOZO app allows her and I to adjust the sound to our own tastes, which is a great feature. The batteries have lasted over 30 listening hours in the charging case. The charging case is small enough for me to drop it into my pants pocket or for my wife to drop into her sling bag. The TOZO O2 was an excellent choice for us and I would strongly recommend them to anyone who is on the go and enjoys great sound, and especially so for those who can not comfortably wear earbuds.

### ⭐⭐⭐⭐⭐ These sound almost good as Shokz OpenFit Pro and fit better!
*by M***X on March 11, 2026*

I can't stand in-ear buds. They feel like the Ceti Alpha 5 sand bugs Khan put in Ckekov's ear. I can't do full headphones, either. Several years in talk radio made me loathe having them clamped on my head for 6 hours/day. So, it's over-the-ear buds or nothing for me. I spent $250 on the new Shokz OpenFit Pro. They sound amazing for music and calls, but just didn't fit well, especially on my right ear. Returned them and bought the Tozo O2 for $37 on sale from Amazon about a week ago. First thing I noticed was the fit -- snug and comfy on BOTH ears. Second was the sound -- clear with just enough bass for my music (NIN the GOAT!!). Also crisp/clear phone calls with no annoying delay on either end. The Tozo O2 are excellent and very easy on the wallet. I'll see how they hold up over time. Even if they fail after 6 months, I could buy 7 or 8 of them before spending as much for the Shokz OpenFit Pro. Highest recommendation!
