I recently sent in a review , after one of my earbuds failed to have any sound, and after contacting Tozo via email, I was told I would they would send me a new set. Tozo followed through and my new earbuds have recently arrived, ( see picture). I was impressed with just one earbud working, but having two is totally amazing. Small enough to fit and stay in my tiny ears, as I have tried many different types of earbuds, and earphones and found they were either too large and uncomfortable or they kept falling out. The sound quality is brilliant. Noise reduction is great, my family thought I was ignoring them, so shows they block out other sounds perfectly. I mainly use mine for audiobooks and meditation apps and they are comfy enough to go to sleep in. Added bonus is they are waterproof and I have used them in the shower with no problem. No connection issues with my iphone 11 and I can leave my phone in the house and go in my back garden ( which is about 10 meters and not loose any signal unless I am practically over the fence. Charging is simple, came with charging case, lead and a set of different sized silicone tips. After a full charge they last for hours without recharging( I had a long journey to cornwall and they were still going after 7hours), although I do tend to put them in the charger every time I take them out. They can be used individually, and once you get the hang of the controls they are simple to use, just remember to pause before taking them out as they can sometimes skip forward if you touch the top of the right one whilst taking out. Id definitely consider buying the newer versions in future but for now these have proved a fantastic cheaper alternative to other more expensive popular wireless earbuds . Anyone having any issues just get in touch with Tozo , you wont regret it. It took less than two weeks to get the replacement buds and it has been the best customer care, I have experienced. Great value for money , Tozo is a brand to be trusted.
