Excellent first pair of wireless earbuds, better than expected
I bought these for my wife, who has had wired earbuds before, but these are her first pair of wireless earbuds. I, on the other hand, have used wireless earbuds extensively for many years and currently have 2 premium pairs one from Sony, the other from Tozo. When I said that I would buy these earbuds for her, she liked the look of them, they look a lot like the Apple Airpod Pro earbuds and she requested them in black. The main reason for buying them was to use for phone calls, so that she did not have to hold her phone up to her ear, which can be quite tiresome especially on long phone calls. When they arrived, she could not get them to work, so I pointed out that they first needed to be paired with her phone, which I did for her: Setting, Connections, Bluetooth, make sure Bluetooth is turned on, Scan (for devices), select Tozo A2 (when it becomes listed) and Connect. This worked quickly and we checked the connection by playing some music she had on her phone. I noted that the sound quality was not as good as what I am used to with my earbuds, but since each pair of mine cost 10 time the price of these, it would be surprising if they were as good. However, my wife says that the sound quality is pretty good, which is all that matters. Now they are paired, the earbuds connect automatically with her phone, each time she uses them. On phone calls she no longer has to hold her phone up to her ear, which is far more comfortable. Also, according to her mother, who is hard of hearing, the call quality is better with the earbuds than without, making it much easier for her mother to hear what is being said, which is an unexpected bonus. The battery life also seems to be surprisingly good. My wife has now got used to the earbuds and is really enjoying using them. She really likes the magnetic feature so that they fit correctly in the charging box. She tends not to listen to music by this method as much as me but she is looking forward to using them on long flights to distract from the noise of the plane and other passengers. They are definitely worth the price tag and are a great pair for people just getting started with earbuds or who want a pair at a very reasonable price.

Brilliant earphones.
These openear headphones are my first dip into this style. Whilst I will be using my TOZO NC3 as a reference point, this is not a companion review. I use headphones daily for the gym and am always looking for the perfect set. I was apprehensive on both sound quality and fit of these, not because of the brand but more so the design. I have worn these for some weeks now and put them through their paces in the gym. I initially found them fiddly to put on and get into the right position, mainly due to the more simple design I’ve been used to. However, after a couple of uses, it soon became second nature and now they just seem to slot into place. The sound quality is excellent and paired with the app, you can set your own preferences. I was surprised as to how clear they are especially given that they are not like the more traditional earbuds with silicone tips. They are not designed to, nor do they cancel out other noises. However, once these are positioned correctly, ambient and background noise is just that. You can concentrate on your music whilst still knowing what’s going on around you. These have not fallen out or moved during any workout and the functions are easily operated even with sweaty fingers. Having a slightly bigger surface area helps with this. Another benefit is no stress or irritation in your ear. I am sure this is also healthy and more gentle on hearing Battery life is very good and with the clear display on the case, you should be able to monitor when these need charging. You also get a nice little repeated noise in your ear once the charge is too low. Connection to Bluetooth was easy and worked first time. For me, it still comes down to what type of workout I’m doing, whether there’s any classes and excess music in the background as to which ones I wear. I always keep both in my bag so I have a choice. Another good choice.

TOZO A2 - Compact, comfortable and let’s face it, cheap
Can you imagine just a couple of years ago being marginally disappointed by a pair of £15 wireless headphones? That’s how far tech’s come. They’re *almost* disposable, however if they’re anything like an older pair of TOZO buds I have, I hope they’ll be going for a few years to come. These tiny little ear buds are ridiculously low in cost, very easy to pair, and have simple pause/play, volume up/down, skip, call answer/end functionality in just a tap or hold to left or right bud. Simple. It’s daft to think too long and hard about the depth of the bass or brightness of the higher frequencies, if you want AirPods sound, spend AirPod money. If you want to listen to podcasts while making and taking calls walking the dog, here you go. They look the part, surprisingly high in quality. Arrive in a tiny case (ready charged too!) and slot very comfortably and securely into your ear. A range of silicone buds are included to suit you in person as you’d expect. Charging is via USB-C, a USB-A to C cable is included and the case accepts rapid charging (not wireless, remember you’ve only spent £15). These are perfect as a back up pair of buds, or even to work hands free in your home office, the built-in microphone works surprisingly well with call quality at either end more than tolerable.

Superb quality, bright sound, long battery life and fantastic live translation
Well, what a surprise. I had always had in-ear earbuds previously, and liked the ‘enclosed’ feeling that I received, isolation from the background noise, and a strong and loud performance too. These are - almost literally - a breath of fresh air. These ear-buds allow natural ventilation in and around the ear, so you don’t get the ‘hot, sweaty’ feel that previously, I have always had. These stay cool, and because they are ‘on-ear’ rather than ‘in-ear’, you can still be fully aware of environmental happenings, such as other people, cars, motor-bikes etc., and are no longer in a self-absorbed insulated cocoon. Much, much healthier and safer for cyclists, runners, joggers or anyone, who is out and about. And then we get on to the actual sound. The 14.2mm dynamic drivers really lay it on to you. It’s unlikely these units won’t be loud enough for you, they can-be fantastically load, but even when they are set to lower volume, I can still hear every detail, from the quietest triangle in the orchestra, to the big bass drum and cymbal crashes. They are very well built, with a charging case offering USB-C or wireless charging, and the earbuds promise 8.5 hours on a single charge, and, up to 35 hours by using the slim chatting case. Need a quick boost of charge? Just 10 minutes of charging will give you up to 2 hours of play-time. The case shows the main case battery charge as well as informing you of the state of charge of each ear-bud. If you are one of the small number of people who actually use their phone for phone calls (???), they have you covered too, with an excellent dual-microphone DNS call noise reduction and call noise-reduction. And then we get on to the built in 164 language AI translation. It will record meetings, provide simultaneous interpretation - on-ear, or even face-to-face bi-lingual conversation. I am delighted with these headphones, and look forward to seeing other future offerings from Tozo in the future.

Far Better Than Expected
I’ve been using these headphones for a while and they’ve turned out better than I expected. The open-ear design is comfortable and avoids the pressure you get with in-ear buds. The adjustable hooks make them secure without being awkward, and once you’ve worn them a couple of times they just slot into place naturally. Sound quality is solid. Vocals are clear, bass is present without being muddy, and they work well for both music and podcasts. They don’t block out background noise completely, but that’s part of the design. It’s actually useful when running or working in shared spaces because you stay aware of what’s going on around you. Battery life is strong. A short charge gives hours of use, and the case display makes it easy to keep track of power levels. They last through a full day without issue, and the quick-charge feature is genuinely handy when you’re about to head out. Build quality feels good. They’re lightweight but sturdy enough for daily use. The app integration adds flexibility with EQ settings, which is nice if you want to fine-tune things. Overall, they balance comfort, practicality, and performance. They’re not trying to be premium studio gear, but for everyday use they’re excellent value. I’d recommend them to anyone who wants headphones that don’t dig into your ears, stay put during exercise, and deliver clear, balanced sound without breaking the bank.

Really comfortable, but lacking on sound
These look nice, both in the ear and the case and they're really comfortable when you've got the right buds in. I'm really quite disappointed with the sound though - Specifically how loud these go (or don't go, I should say). Sound quality itself, is fine. I'm not too fussy in that department though, so can't comment too much. They're not very noise cancelling - Not too bad, but not fantastic either. Same with sound leak. OK, not great They do look nice, and weren't expensive (I think I paid £22 / £24?) but I really do wish they went louder.

Excellent open earphones - perfect for running
I bought these to use whilst running, and I'm pleased that they are perfect for that. The loops swivel sideways and up and down so you can get a really snug fit with the 'earphone' part tucked next to the opening of your ear. It doesn't move or fall off when running! The sound quality is also great but you can still hear noise from cars/people etc around you. Comes in a thin case, took seconds to pair and worked straight away. The battery percentage indicator on the case is a nice touch. Would recommend!

Pleasantly surprised
I must say I am pleasantly surprised by these headphones. Firstly, they are very compact and can easily fit into any pocket which makes it very easy to carry around with you. The multiple ear tips, which were provided, allows you to find the perfect fit for the earphones in your ears. The sound quality is clear. There is nothing bad to say about them at all considering the budget friendly price. They are comfortable to wear and lightweight allowing one to to use these headphones for long periods of time without discomfort. The instruction manual is also clear. They were very easy to pair with my phone; it took within 20 seconds to pair when out of the box. Overall, these earphones are very good. When looking at the price, you ought to think that it would not be the best but it has surprised me a lot. I am very happy with this and will continue to use them.
