Great sound, Great fit and Great adjustability!!
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.

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.

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.

AMAZING, I own 2 pairs and would buy again
These Things are SICK Only wireless earbuds I use as since I don’t like stuff going into my ears. They never come off and always connect seamlessly and at such a good price too. I’ve already bought a Second pair since I lost my first at an all inclusive in turkey. I also own a third one as a backup. Sound quality is good enough for me, I have other headphones when I wanna listen to stuff properly but for gym running or general use these are fantastic.

Differences in my left / right hearing but no L/R balance control
I really liked these ear buds, especially at the price, but I have sadly had to return them. First the good bits. I bought them because of the flexibility of the fit and this met my expectations. The sound levels was excellent and bass response was very good. The standard EQ settings were a bit restrictive but would have been acceptable as my main use is for audio books and podcasts. They were lightweight and I wasn’t really aware of them during use. The down side was the sensitivity of the touch controls. The slightest touch would activate the single tap function chosen from the customisable menu. Taking them off whilst out and putting them in my pocket often activated the play function, which meant I lost my place in the audio books. Turning off via a long press was hit and miss, and again seemed to turn on in my pocket with the slightest touch. I could have lived with this but reason I decided to return them centred around the size of the bud in relation to my ears. It was a perfect fit on one side but the other held the bud further away from the ear canal. This is caused by my ears, not the design, but the outcome was that volumes were different for each ear and that put the “sound stage” off to one side. This may also been caused by differences in my hearing levels. If the App had a left / right balance control I would have adjusted the soundstage and kept these buds, but it does not. I’m now looking for open ear buds with adjustable left / right balance.

Quality and comfort with little compromise
I recently got these TOZO Open Buds and I have to admit I am impressed. I wanted to try out an open ear design due to the ear fatigue I get from using in-ear earbuds for long periods, and so far I am happy with the results. They are light and comfortable around the ear, and easily adjustable to get a secure fit. I have using them pretty heavily for about a week and I have to say that I am able to wear these for hours on end without fatigue or discomfort. The battery life on these are great as well as they have yet to die out on me during a listening session. The audio quality is great and it is nice to be able to change EQ curve settings on the TOZO app. These perhaps lack the deep bass that an in-ear headphone would offer but I am happy with the overall sound balance with these. The fact they are open-ear as well allows me to be a bit more aware of my environment, which is useful when going for a jog or doing chores around the house. The only downside (and its a minor one) is that the case is on the bulky side but it makes sense considering the design of the OpenBuds. But it does provide a lot of extra juice for your buds for a couple of quick recharges on the go. Overall I am happy with these and they fit the bill for the comfort and open-ear design I wanted. I can easily recommend these if these are the attributes you are looking for in your next set of earbuds.

There is a major design flaw with these - don't buy
Let me start by saying that these earbuds work fine, and sound good. Out of the box everything was ok. However after about a month the problem started. The issue is that the buds are charged by a small spring loaded metal component in the case. Over time the spring loaded function stops working so that the piece of metal becomes permantly stuck inside the case and one of the buds no longer charges. I actually liked these buds when they worked and they were relatively cheap so I though i would give them another go. EXACTLY THE SAME FAULT OCCURRED WITH THE 2ND PAIR. Customer support was none existant and the app that controls the buds is also rubbish. Save your money - find an alternative

TOZO Earbuds Review: A Practical and Affordable Choice for Everyday Use
I recently had to travel and was on the lookout for a compact, affordable, and reliable pair of earphones. After reading many reviews on Amazon, I decided to try the TOZO A1 Wireless Earbuds. Overall, I was quite satisfied with their performance — the sound quality was good, they were easy to carry, and the battery life was decent. The only minor downside I experienced was occasional itchiness in my inner ears during extended use. Having developed some trust in the TOZO brand, I later tried the TOZO HT2 over-ear headset when I was searching for something that didn’t go inside the ear canal. While the HT2 offered good sound and a full-ear coverage, I found them uncomfortable after long periods, as my ears and head would get very hot. That's when I discovered TOZO’s outer-ear wireless earbuds — and I’m glad I did. They have a retro look, reminiscent of first-generation Bluetooth headsets, and they sit outside the ear canal, which I find much more comfortable. The earbuds can be rotated horizontally and vertically, which adds to their adjustability and ergonomic design. Pros: Good sound quality: Clear and crisp, even without active noise cancellation. Fast charging: They power up quickly, which is great for frequent use. Improved microphone: Calls sound noticeably better than with the A1 version. Comfortable outer-ear fit: No more inner-ear irritation. Cons: Bulky charging case: The plastic feels rigid and slightly cheap, and the size makes it uncomfortable to carry in your pocket. Non-interchangeable earbuds: You can’t switch the left and right earbuds — they’re fixed to each ear. No active noise cancellation: Not a deal-breaker, but worth noting. Despite a few drawbacks, I’m happy with my purchase so far. TOZO continues to deliver quality audio products at a budget-friendly price. These outer-ear earbuds are especially great if you’re looking for something more breathable and less invasive than in-ear designs.

Comodidad, calidad, precio
He comprado auriculares de diferentes tipos con el fin de identificarme más con uno de ellos y a continuación os ayudaré a conocer también como responden físicamente unos y otros para que os decanteis por alguno en particular. Los auriculares pueden ser: In ear On ear Supraurales Los IN EAR van alojados con cualquiera de las almohadillas que disponen dentro del oido y el sonido se percibe internamente y no son escuchados por otra persona que se encuentre próxima. Los ON EAR son auriculares que se colocan con un gancho normalmente de silicona alrededor de la oreja y quedan paralelos al oído sin entrar en el. Los SUPRAURALES son los conocidos como auriculares de diadema y van acoplados en cada oreja e incorporan una almohadilla para que resulten más cómodos. Tengo de los 3 modelos y cada uno presenta ventajas e inconvenientes en funcion del oído de cada persona. A mi, la mayor parte de los In Ear o se me caen o me cansan al cabo de un tiempo por lo que si estoy tiempo acabo por cambiarme a un OnEar o Supraurales. Tiene la ventaja de que son muy reducidos de tamaño y se escuchan muy bien y no los escucha otra persona que este cerca de ti. Los SUORAURALES o de diadema resultan cómodos pero abultan excesivamente. Los On Ear son precisamente los TOZO O2 que he adquirido. Se colocan alrededor de la oreja, no cansan, son móviles lo que permite ajustarles bien al oído. Tengo otra marca pero reconozco que estos el sonido que percibes es bastante bueno, la bateria dura hasta 42 horas (extraordinario), llevan cancelación de ruido para aislarse un poco más del exterior, el sistema bluethoot es 5.3 lo que asegura muy buena conectividad, también permite doble emparejamiento lo que facilita la utilización en 2 medios diferentes y tienen un grado IPX6 lo que confiere un buen aislamiento a la humedad y por último la relación calidad/precio es fantástica. Utilizo los 3 tipos por lo señalado en cada caso pero con los que acabo de adquirir me encuentro muy satisfecho y los recomiendo.

These are great! Such a great buy.
I ordered these last week and they arrived fast enough for me to be able to use them as soon as I can. Audio quality from the open buds are very nice. May it be from music, down to calls. Perfect. Painful? Nope. They are very much comfortable to wear on the ears. Even if you use them for a long time. I bought these most especially for calls. The mic is great. A week of calls made using these open buds, and there has been no complaints about how unclear my voice is (which happens a lot when I use most of my old earphones). Which means the mic works very fine. And they surely make me happy. These work well too, even with some bit of distance between me and my device. And lastly, they are very comfy when you are the type of person who likes to move around much while having something to listen to a lot. I run and use these at the gym and they are amazing. Definitely worth the buy! Worth recommending. Thanks.

Open ear wireless earbuds for people with glasses with a sound with quality
I tried an open ear wireless earbud from another brand before. Because I couldn't use it with my glasses, I immediately returned it. But I still wanted to have one because open ear product is more comfortable for ears in general if I need to listen to music for a long time while I still need to hear my surroundings. This product satisfies all of them. It is comfortable even with my glasses, the outside sound is still audible and the sound quality is very good considering the price. Why is it comfortable? It is because the ear holder(?) is very flexible and can be bent in many ways. I would recommend this to anyone who needs to wear glasses and wants to have a good sound quality.

Ottimo prodotto, comodi e suono molto soddisfacente.
Auricolare lungo circa 3 cm. Al momento funzionano egregiamente, sono comodi all orecchio (indosso anche gli occhiali, ma per ora non ho sentito fastidio nonostante l'averli indossati per diverso tempo guardando qualche serie tv), suono molto chiaro e volume più che ottimo (testati in motorino, sentivo benissimo la musica alzando il volume). Funzionano benissimo con i miei dispositivi, hanno un raggio di azione direi perfetto, davvero esteso. Si possono collegare contemporaneamente a più dispositivi. Direi che il rapporto qualità/prezzo è davvero ottimo. Tornerò se avrò qualche lato negativo da riportare.

Mükemmel
Bundan daha iyi bir kulaklık olamaz. kulağın içine girmiyor, kulağın üstüne tencere kapağı gibi kocaman padlerle kapatmıyor, ses mükemmel, en güzel tarafı istediğiniz yöne istediğiniz gibi ayarlayabilmeniz. yukarı aşağı sağa sola ileri geri nasıl istiyorsan ve inanılmaz hafif var olduğunu hissedemezsiniz. kulaklığı geçtim şimdiye kadar aldığım en iyi teknolojik alet olabilir.
