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.

Comfort Meets Clarity in a Versatile Package
After using the TOZO O2 Open Ear Wireless Headphones, I can confidently say they're a solid choice for anyone looking for comfortable, versatile earbuds.Pros:Comfort: The open-ear design is incredibly comfortable, even for extended wear. No more ear fatigue!Adjustable fit: The dual-axis rotation allows for a customized, secure fit.Sound quality: Surprisingly good for open-ear design, with clear audio and decent bass.Awareness: You can still hear your surroundings, great for outdoor activities or office use.Call quality: The noise cancellation for calls works well, making conversations clear.Battery life: Up to 42 hours with the charging case is impressive.Dual device connectivity: Handy for switching between phone and laptop.Cons:Sound leakage: At higher volumes, others nearby might hear your audio.Volume floor: The lowest setting might still be too loud for some users.Case size: Slightly bulkier than some in-ear models' cases.No wireless charging: The case charges via USB-C only.Overall thoughts:The TOZO O2 headphones have become my go-to for daily use. They strike an excellent balance between audio quality and environmental awareness. The comfort level is top-notch - I often forget I'm wearing them.The sound quality exceeded my expectations for open-ear buds. While audiophiles might notice some limitations, for most users, the audio is clear and enjoyable. The effective call noise cancellation is a big plus for work-from-home situations.The main drawback is the sound leakage at higher volumes, which might be an issue in quiet environments. Also, while the battery life is good, the lack of wireless charging for the case feels like a missed opportunity.In conclusion, if you're looking for comfortable earbuds that don't isolate you from your surroundings, the TOZO O2 is an excellent choice. They're particularly well-suited for outdoor activities, office work, or anyone who finds traditional in-ear buds uncomfortable. Despite a few minor drawbacks, they offer great value for money and have become an essential part of my daily routine.

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 OpenBudsPrice at the time of purchase: £55.99They were packaged well and arrived the day after ordering.

AMAZING, I own 2 pairs and would buy again
These Things are SICKOnly 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.

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

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.

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.

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.

Bass response is not as advertised!! Not able to return.
If you like a bassy tone and sound. Then skip this product. Spend a bit more on a better product. I tried to play this first day. Was disappointed on the bass response. It is distorted and did not sound good. I won't be using it again. Hurts my ear. When I try to return it. The vendor send me labels but because of the lithium batteries inside. Dhl requested for an airway bill label from Amazon, otherwise they won't accept it to sent it back. But the vendor did not understand and amazon have no hotline to call. Warning to all who buy wireless products as there are 3 no of lithium batteries so it may not able to sent it back if you want a refund. So I am stuck with an useless earpiece .
