TOZO OpenBuds Review – Another Win

I recently reviewed the OpenReal open-air neckband headphones from TOZO, and it sold me on the concept. The OpenBuds are similar to the OpenReal, but they’re true wireless earbuds instead of neckband headphones. They cost a bit more than the OpenReal at $69.99, which is still a very affordable price. Let’s see if they’re just as good.

TOZO OpenBuds Review

Look & Feel

My favorite part about these earbuds is the adjustable ear hooks. They make the fit feel very versatile, especially considering the style of housing the OpenBuds possess. In terms of design, the OpenBuds aren’t anything that special, but it’s perfectly fine for the price.

With the innovative biaxial rotation design, you can adjust the angle of the earbuds in two ways to suit your preferences and needs and I confirm this feature works very well.

Design & Functionality

Like the OpenReal, the OpenBuds possess pretty sizable drivers. They have 14.2mm dynamic units, and feature TOZO’s ORIGX acoustic technology. This tech keeps the sound isolated to you, preventing leakage. While there’s still some audible sound that can be heard, it’s minuscule compared to other bone conduction or open-air earbuds. There’s a good touch interface on the left and right panels that feels very responsive, and the app has a good amount of features including EQ. However, the EQ isn’t very customizable and only offers a couple of presets.

I would like to thank TOZO for providing me with the review sample of OpenBuds.



TOZO OpenBuds has an extremely smooth and natural sound. Its stand-out feature is a vivid and wonderfully textured mid-range that is forward without being shouty, and which puts vocals and instruments front and center. TOZO OpenBuds’s tone makes it great-sounding, but what makes it special-sounding is its very good sense of space and imaging. A genuine out-of-head experience.

TOZO OpenBuds Review


From what I’ve experienced, open earphones like the OpenBuds shouldn’t be expected to house a ton of bass. However, the OpenBuds are capable of more than you might expect. You get more body to the overall tone here, and it’s more balanced with the rest of the sound signature. There’s more volume to bass instruments, giving them more clarity, but the response could still use more legs. The bass could be something special if it just had some support from underneath, but no harm is done by the timbre that the lows already exhibit.

Most of the midrange frequencies act well throughout the mix. Instruments are more emphasized in the low-mids, giving certain performances like metal guitars a bit more life. It features little recession in the middle, but you can tell there is more artificial coloration than pure detail. This makes these mids less roomy, but it’s what I’ve come to expect from true wireless earbuds over the years. With that said, there is a lot of vocal clarity here, and it makes most tracks pop. It’s where the crisper textures hide, and it makes them cut through the sound signature with more force.

Nothing about the highs sticks out too significantly, but everything stays pretty smooth. You get a good splash from cymbals, with some average height and texture, but the frequencies don’t possess much gain in general. The OpenBuds play it safe, and you can’t fault them for it when the timbre is still clean and unobtrusive.

TOZO OpenBuds Review


Now that I’m more familiar with these open-ear designs, I know what I should come to expect. The OpenReal was more of a neckband headphone, and the OpenBuds are more true wireless. These buds do mostly everything that I liked about the OpenReal. It’s surprisingly wide, with a wingspan that feels bigger than you’d expect. You have individual instruments that come through the mix with elegant layering and good separation, however, you don’t get as much of the room that the OpenReal can portray. Everything still feels like a bubble, presenting spatial imaging non-linearly for deeper immersion.

TOZO OpenBuds is a wonderful set of TWS, Open TWS we can say, that promises quality sound, stable wireless connectivity, and also keeps us aware of our surroundings. It produces a balanced and lively tuning that complements different genres of music well.

The OpenBuds are another win for TOZO, which constantly gives you reliable and good-sounding Bluetooth earphones that are very affordable.
