Review: Comfortable and a great fit, well worth the money. - When I came across these, they seemed like the perfect solution for me, and they honestly exceeded expectations. In-ear headphones never seemed to fit properly for me. The ones without an ear hook would quickly fall out, and for those with one, the angle never seemed quite right to hold well. These are adjustable, so they fit well and hold more securely than any other earphones I’ve ever owned. They’re also small enough to be able to take out with you, a benefit that over-ear headphones never had. While more comfortable than in-ear ones, over-ear ones also seemed to get uncomfortable after a couple hours. These seem to be the most comfortable earphones I’ve ever owned, and I could easily wear them the whole day without issue. I hate being heard and pretty much always use my devices on mute, so having headphones that can be worn all day is a huge help as music helps my mood a lot. They can also be worn with glasses without issues, so thats a pretty big plus. Wearing in-ear ones, I would always worry about them potentially causing damage and effecting my hearing overtime. They always seemed to need cleaning after every use as well, which was a bit annoying. However, these don’t go in your ear, so I’m not constantly worried about having them on and can wear them for longer. They are touch operated, which means I can use the back of my hand or wrist to operate them instead. This probably doesn’t matter much for most people, but my hands sweat pretty excessively which can end up damaging things. Usually I would just avoid touching them after putting them on, but these are extremely easy to operate while also not requiring proper contact. I have managed to accidentally pause them a few times, but it’s just a matter of getting used to them. Luckily, they aren’t too sensitive, so they don’t get paused by hair. I can’t comment much on the sound quality, I’m not an expert on the technical side of things, but they definitely don’t sound bad. I do wish it was possible to lower the volume a little more though. While loud music is okay at times, sometimes you only want it on quietly, but even the lowest volume seems quite loud on these. Perhaps thats just me, as I’ve always been more sensitive with sounds. They do seem to leak sound more than other headphones I’ve used, perhaps due to the open design, but they’re fine on the lowest volume and I honestly wouldn’t want them any louder most of the time. It’s possible to only have one on at a time, which is nice as it’s easier to stay aware of your surroundings that way. They aren’t too noticeable if your hair is long enough to cover them, at least using the black ones with a darker hair colour anyway, which is also a plus as I’d be too self-conscious to wear them around people otherwise. They also come with a warranty, but you do have to sign up for it within 14 days. Product: TOZO OpenBuds Price at the time of purchase: £55.99 They were packaged well and arrived the day after ordering.
Review: Great sound but... - PRO's: The most important thing is they give a great sound and loud if you want it too. If you need open ears buds the adjustability is a big plus, but I would say that you couldn't wear them for longer than a couple of hours before they get uncomfortable. They connected really easily to my iphone and to my Sony hi-fi (using a bluetooth transmitter). The batteries seems to last forever, I've had no issues with them losing charge after many hpurs of music and 2 hour phone calls. People I've called have no idea I'm using these Open Ear Buds, they tell me I'm crystal clear with no more background noise than if I was just using the phone. CONS: They can get uncomfortable after a while. The touch pads are very sensitive which can be annoying if your just scratching an ear. Don't be fooled by the 'App. equaliser' PR. With the Open Ear Buds it is not set up for use, there are 5 settings only with these, in EQ Zone (on the 'Home' page) press 'Current EQ' and you can have Standard, Bass+, Classical, Vocal or Treble+. There's nothing wrong with these 5 but if you want to create your own or try out others you can't, hence 4 stars not 5. They are great value for money though when you can pay twice as much for a similar sound.

### ⭐⭐⭐⭐⭐ Great sound, Great fit and Great adjustability!!
*by L***N on 8 May 2025*

I have a variety of earbuds and headphones but in terms of earbuds i just can't get the right fit in my ear and sometimes they fall out and they can be uncomfortable to wear for long periods. I saw these reviewed on YouTube by Flossy Carter who raved about the fit and sound so I thought I would try them. I also wear glasses so the fit and comfort was also a big consideration. When they arrived, I noticed how adjustable they were in terms of their movement. I paired them to my Samsung S24 Ultra phone which was very easy through the app. The app is fairly basic with a few EQ settings but I needn't have worried as the sound is spectacular. Really good for sub £40 open earbuds. the over ear arm and the speaker part are so configurable to get the position just right. The speaker part covers your eardrum so the sound really does go into your ear, so you get less leakage and you can hear what's going on around you. if you want total silence from your surroundings though, these aren't for you. The touch controls on the right earbud is good but there is a little lag, perhaps that will be fixed in a firmware update. Just a quick note on the fit especially from a glasses point of view. They were easy to fit around my ear and because the arm is thin it doesn't really cause any issues and they aren't uncomfortable. The case is quite large and there is a single light to tell you the status of the earbud and case battery. I would have liked some display to show the percentage like on other Tozo products but you can't have everything. Maybe that will be on the next upgraded model they bring out. On the question of support, I opened a chat message to Tozo support and they actually came back straight away which is nice to know. The earbuds also have an 18 month warranty. Overall, these are really excellent for the price and I highly recommend them. Great fit, Great sound and Great range of adjustment.
