Definitely the way forward for ear phone/ buds
I really struggle with ear phone/ buds of any description. These are absolutely perfect! No problem with glasses, comfort, having small ear canals or them falling out. I bought 2 pairs. They are definitely the way forward!. Great sound anytime. Great battery life. As good as the expensive branded ones. Also come with a long guarantee. I will not be using anything else. Great value for money.

THE WAY FORWARD - a revolution in earphones
I LOVE THESE. WOW. so comfortable you forget you’re wearing them and the sound quality is incredible. As a musician, I am very critical of sound quality and usually find non apple earbuds or earphones a bit tinny. Ok for audible I guess but not good enough for music. I love hearing the bass whilst balancing the levels and hearing all the range of sounds and elements instruments/vocals etc. I refuse to pay £100s for apple earbuds and I cannot imagine they would better these. A great price and a quality product. I’ve had them nearly a week and rarely taken them off. I’m only just today recharging the pod they live in. I am amazed as I was a bit sceptical having always had the standard ear buds. Once you get used to putting them in differently they sit comfortably and lightly around the ear. They instantly connect and stay connected really well too - I can walk all around the house with my phone in one room. The touch functions work well. I have to say I prefer a button press as it can be easy to activate the wrong function by touch (with all touch function earbuds) but they seem a rarity so I have accepted the change. I tend to operate most functions from my phone anyway just using the pause / play (double tap) function when out walking or at the gym. They stay in place when I’m working out at the gym even when changing tops - A major benefit over traditional ones which are easily pulled off. You really do forget they are on as they feel so much more comfortable than the traditional bud style. I also prefer to be aware of my surroundings - these do not cancel out noise - I have headphones for that but still prefer these. I really cannot find fault so far. Early days but if they are still going strong in a few months I’ll update this review. 10 out of 10 so far. I’m so glad I tried something different. This is the next generation earphones at a price we can afford. Nice job TOZO !!

Good little headset
New to open ear earphones but these were easy to set up app and pair to mobile phone. They sound very pleasant once they are on the right way round! The larger bit with the logo goes behind the ear and the black bobble earphone bit; the speaker is well hidden and goes to the front of the ear. Can’t get the volume to go up or down but may just take a bit of practice using the earphones I used my music app to adjust the volume. The Tozo app has an EQ with choices of genre and also a customised EQ. Fairly comfortable to wear but I have only tried for 10 minutes so far and certainly more comfortable than ‘stick in the ear’ earbuds. Sound as expected is not as good as noise cancelling earbuds but sensibly and why I wanted to try open ear earphones; I can hear traffic when wearing these outdoors. The case charges using a USB-C cable and is not wireless charging as suggested by AI questions and Amazon advert. Tried charging on 2 different wireless chargers but no luck. The case will hold a charge to power earphones when away from home. I like the simple power meter to show how much charge is left, just wish the case could use a wireless charging pad.

Amazing call quality
I took my time before writing this review and has tried these amazing headphones for about a month now. The design is so sleek and modern and looks very high end. The sound quality is outstanding, although they do not beat the top of the line ones if you want the best music output but very reasonable for the price. The thing which has impressed me the mist is the call quality which is better than all the apple products I’ve tried so far. No robotic sound, no muffling, very clear mic output inside the house, in car or wherever you are. I have been taking work calls, team meetings with these and flawless sound.

Awesome buds!!!!
OMG! These are a game changer in ear buds! I can hardly feel them in my ears, the fit is AMAZING and the sound clarity is great! They paired instantly with my phone and they arrived fully charged too! For the price these are quite simply the best value earphones I have ever tried.

Sound quality great for the price; however, not suitable for any rigorous activity.
Sound quality was great; however, the buds kept falling out of my ears during any activity that involved movement more vigorous than walking. Not useful during any form of exercise i.e., running, gym or activities that required bending, climbing, reaching etc.

100/100 warranty is included
* 18 month WARRANTY IS INCLUDED PLEASE READ. I absolutely adore these open ear, ear phones. When I have them placed, they are not in my ear but they cup my ear pretty nicely. I love how they aren’t in my ear and irritate me, Infact they make me enjoy whatever I’m listening to more better. There is clarity in everything from the design, weight and the actual product. The connectivity is out of this world as you can walk around away from your connected device to do something and still have crisp sound. you also get warranty for 18 month, it’s a simple process as you need to scan bar code, which directs you to a form, fill it out OPEN EAR RING, Your name, email, and order number. The form will be sent off and you’ll get a certificate too emailed to you. You do need to apply within 14 days. The batteries on these things are also impeccable as I was up for the night and I listened to music, YouTube vids etc. I’ve still got 80% charge. It will take some time to get use to as I was a wired ear bud wearer for years now I have the piece of mind to be comfortable, stylish and not having to deal with tangled wire. The quality is insanely amazing and it was a good price as I got them on a deal. Best deal ever and money well spent. A satisfied, happy customer thank you.

Je connais et apprécie la marque Tozo mais je ne connaissais pas ce type d'écouteurs. Ils sont parfait au niveau du maintien et le son est très correct. Avec la connection à l'appli cela permet de personnaliser les differents sons selon les besoins. Bref je recommande

Excelente qualidade de som. Mostrador de carregamento de bateria é uma preciosidade. Pelo preço pago, é uma pechincha. Não vão se arrepender.
