TOZO O2: Finding the Fit with Its Clicking Ear Hooks
Opening the case, adjusting the earpieces and pairing them for a first listen.
Article published November 4, 2026.
I am briefly confused about how to put the TOZO O2 on. Then the clicking adjustment in the hook makes sense, and I can move the earpiece into a position that feels comfortable to me.
Open the case and adjust the hooks
I take out the guide and charging cable, remove the protective covers and look over the charging contacts. The adjustable hook is the part I spend the most time trying.
Once it is around my ear, I can change the angle of the speaker section. That gives me more room to find a position than a completely fixed shape would.
Pairing and the first music listen
I use the case's pairing button, close and reopen the case and find the O2 on my phone. During the short listen, I am surprised by the volume and turn it down while talking.
I like the clarity, with bass that feels more restrained than a sealed design. I can still hear the room around me; that is my experience here, without establishing a safety or sound-isolation result.
Hooks or an earring-style clip?
My TOZO OpenEarRing first look uses another way to hold the speaker beside the ear. These videos are useful for seeing the different shapes, rather than deciding which fits every listener.
I finish this O2 session wanting to try calls and longer use. Those checks, the app's extra features and the long runtime in the description are not tested in this recording. The original product link is below.
