Review: Brilliant for those who don't like the in-ear design of buds - The T20 tonal earphones have a similar case to the T21. The blue colour is beautiful. These earphones are one-size-fits-all so you don’t have to worry about finding the right sized eartips. They feel solid in the hand. They are shaped individually for ergonomic fit into each ear. The bass response on these is pretty good. Tozo have clearly tuned these to be bass heavy to compensate for the semi-open design. Unfortunately, this makes then sound muddy. The one-size approach means some people will find they fall out of your ears. I don’t mind this so much as you benefit from the openness. There is no occulation issue here and these are great for people who don’t like the sensation of being closed off with in-ear type earbuds. With this style that has the stem, any adjustment you try to make of the buds means you will end up tapping on the touch sensitive earbud and pause your music. I normally adjust both earbuds one at a time so I end up pausing my music when adjusting the right ear and resuming it again when adjusting the left. I do not have this issue with other non-stem style earbuds. The good news is that when using the Tozo app you can chose what the touch controls do. You can even switch them off completely if this bothers you. Considering that these do not go into your ear canal, they do not occulate and cause fatigue they offer a punchy sound. You can achieve better sound by using the EQ in the app. They offer wireless charging, USB-C charging and look very elegant with the OLED display. Tozo's products have matured signifcantly. They now have a deign language across their product range and that makes switching between products a seamless breeze
Review: Favourite earphones - 3rd paid we have bought we all have a pair 😄 comfy and good quality to listen too. Not tge best for receiving phone calls but you can. Great for 1 ear and being avle to hear work colleagues or children 😀 great value for money.

### ⭐⭐⭐⭐ Very good quality
*by A***Y on 31 July 2026*

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.
