I’m an avid user of earbuds because I enjoy audiobooks and a variety of music from metal to rap and everything between. I am on the phone a lot and take part in many conference calls and video conferences. While doing all these things I need to hear my family’s texts and the various alarms I set to remind me of my daily meetings and appointments. When I drive home from work I take calls or listen to music and when I’m finally relaxing in the evening I like to watch movies on my phone. Literally every part of my day requires me to have good earbuds which sound great when I need good quality and long battery life as well as a good connection for my phone calls and my colleagues need to clearly hear me on conference calls. I can’t be troubled with low batteries or poor bluetooth. Having said all that, Tozo has been the one brand that I can consistently rely on to get me through my long days. The Tozo T21 check all of my boxes. So far I haven’t had low battery alerts although I typically wear earbuds for 10-11 hours per day. Everyone says that my phone calls are clear whether I’m driving with the windows down or sitting in my office. The mics do an excellent job of picking up my voice but not every sound around me. I really enjoy the Tozo app for adjusting the EQ for my specific needs as my music choices require a variety of different sound profiles. I say this in every review and will continue as long as it remains honest, Tozo is consistently the best quality at an excellent price. You can spend 5x more money and get a product that isn’t on the same level as Tozo. If you’ve never tried their products, stop reading reviews and looking for the best value, you’re already there. Treat yourself to something nice and get some Tozo earbuds. You can get a nice variety of earbuds for very little money.

These earbuds work well with my iPhone 15, and they provide clear sound when listening to music or phone conversations. I like the fact that it has an equalizer function that gives you the ability to adjust your sound quality. Note: You must download the app in order to access this feature. The battery life is good as well. They also fit in my ears and do not fall out inadvertently when turning my head or bending down, unlike the AirPods I purchased that were compatible with my iPhone.

The sound was nice, but they are too big for my ears. I have small ear canals, and I was so looking forward to these after I read they were comfortable. They fit poorly enough that they hurt when they should have been secure, and fell out when pulled away enough to be comfortable. My husband had no issue, but he didn't need a pair so they got sent back. I returned them and got a quick refund.

I decided to pull the trigger on these because I wanted to try the noise canceling option and I’m in love with these. I’ve been a Tozo fan for years and these headphones have everything I love about other Tozo products. Could not be easier to pair, great range, better battery life than any other headphones I’ve tried and very fast charging. They are a great size too. I’ve used AirPods Pro and the noise cancel on these works just as well. Also they are waterproof. I sweat a lot when I work out so the water proof is important to me (AirPods break when I sweat and cost hundreds more). I buy Tozo headphones as gifts because they are very affordable but Bluetooth headphones are always a hit with my friends and family. So much better than spending hundreds on AirPods or Bose and it’s the same thing. Thanks again TOZO

Big thanks to TOZO! 💙 I got their earbuds as a Father’s Day gift for my husband and he absolutely loved them. They’re super modern and complete — clean sound, excellent bass, and really comfortable to wear. They don’t bother the ear at all. Amazing product!

Update: I purchased these in April 2025 and by late July 2025, the left earbud refuses to charge despite my best efforts cleaning up the earbud and the charging hole. After contacting the manufacturer about it, and proving to them with a video that the device has a manufacturing defect, they told me that, despite the warranty saying that I'm eligible for a refund within the 12 month window if there's a manufacturer defect (which this qualifies), that they are refusing the refund because I bought it from Amazon (note: I thought Amazon was an authorized seller). That means buying these products from Amazon is a waste of money. But TOZO is not a good brand and their manufacturing process doesn't care much for precision. You get what you pay for. This is Chinese junk and you will likely have only temporary success with it. This is the 2nd pair of TOZO earbuds that have suffered the same fate. So I filed a complaint against them as a company on Amazon for not honoring the manufactures warranty they sold me with the product I purchased, and despite being out of the replacement or refund window on Amazon by far more than 30 days, but still well within the 12 month manufacturers warranty, Amazon gave me my money back in the form of a gift card and promptly filed my complaint. And they instructed me to leave a negative review.I also asked AI (ChatGPT) for its opinion on TOZO earbuds and it told me:"Reality Check:Many users report terrible support, especially after the 30‑day return window.If customer service is not helpful, you may be out of luck even within warranty.Bottom line: TOZO promises a 12‑month warranty (with possible extension to 18), but enforcement seems sketchy. Buy only from authorized sellers, file claims early with paperwork, and don’t count on stellar support outside the 30‑day window."As far as the fit, I wanted to mention that they're a little big for the gap that they sit in between the ear flap (called the "intertragal notch") and thus become uncomfortable after wearing them for several hours. Also, because there's no rubber tips, they don't have ANC (of course), though I know it's still possible to have ANC without rubber tips but that's really hard to find outside of the airpod variety.

Sound was good, but there are no foam bits to change the size- just smooth plastic going in your ear. They don’t fit snugly in my ears, and I lose enough earbuds as it is to lose one because it just slides out.
