I have purchased the Tozo T6 and A3 earbuds in the past and these have the best call quality for canceling out background noise. Calls sound very clear while driving down the freeway. I have to say that straight out of the box, the audio for music was okay but not ideal. I downloaded the app and played around with the equalizer settings and the sound is way better. Just like the description says, it’s got great high and midrange sound. I do listen to music, but I do more podcasts and audiobooks than anything. They fit nicely in my ears and don’t bulge out like some ear buds do. I love the case with its digital readouts showing the charging levels. It’s also a nice small size, and not too thick so it’s comfortable to just keep in my pocket.

I own a pair of T6s and NC9s. I have (minor) complaints with each of those, but overall, Ive been pleased with TOZO. I saw these and their high reviews and decided to give them a shot. For a few different reasons, Im returning them. - I cant get a good fit. I have relatively large ears. The default size tips are a little too small, and then there are two different larger sizes available, and they are both too large. (One of the large size tips didnt even look like it should be with the crystal buds as the inner-diameter was much too small). After wearing for a couple of hours, I was getting a headache and my ears were killing. The ones that were too small didnt create a seal (bad noise isolation, and poor audio quality), and wanted to fall out. - Instead of spoken notifications (such as disconnected, volume up, pairing, etc.), these just make various beeps and boops. - Speaking of which (and this was the final straw for me), after pulling the earbuds out of their case, instead of reconnecting with my laptop, they just cycled through various beeps and boops. I eventually had to un-pair and re-pair. This happened multiple times. - Default sound profile was really poor, IMO. Not as clear as my T6s and much weaker bass. I was able to play with it in the app and found something acceptable. But anytime going back to my T6s, I felt like it was a step up in audio. Im just going to get the updated T6 with BT5.3 and call it good.

I recently got these earbuds, after having owned several Tozo earbuds before (NC9, and the G1s). All earbuds Ive gotten from Tozo have been fantastic, sound great, and have been reliable. These headsets have great sound, and with the app, you an change the EQ a bit (love the bass increase option). While it may not have noise cancelation, it does have noise reduction which works pretty well.. better than some of the others Ive had. Overall, the quality is great, the price is right, and the sound is amazing. Easy 5 stars.

These have become my favorite earbuds for music & phone calls. They are the most comfortable earbuds Ive ever worn. I have small ears & some buds are uncomfortably large. The sound quality is great, for music & calls. Battery life is great. The features are awesome. The shape of the case fits well in a pocket. Highly recommended!

I have been using an older pair of Tozo ear buds for a long time. They were replaced with a better model for a small additional payment after the first pair I had were defective. Defective products dont bother me too much, especially when the company stands behind their product and helps sort the issue. Tozo did just that. Now I have been using the older pair for a long time and at a fraction of Apple earbuds, I couldnt be happier. So I decided to get a second pair to keep at work, thats the crystal buds. I cant honestly say I need all the added features, but they are nice to have. The main thing is the battery life is fantastic as usual, and the sound quality is on par with my previous pair. Well done Tozo!

After more than a month of using regularly, this earbud, in my opinion, is a very good one to have if you are looking for an extra pair of earbud. I have used many Tozo earbuds before so the quality and build and the technology that Tozo uses is not so strange to me. However, since I already have the nc7, nc9, t10, and if you ever have one of those, this is not a upgrade, but rather is a downgrade. Because: - No voice response when the earbud connected to your bluetooth device. In stead, a notification sound will let you know whether its connected or in pairing mode. - Clear plastic cap is easy to be scratched if you like to store it with other item in your bag. And once its scratched, theyre very noticeable. On the other hand, if you are looking for a new pair of cheap/afforable but good earbud, this one would make you happy. - The clear cap really make your earbud stand out. - Sound quality is good with clear treble and bass. - Touch control is very easy and simple to use. - The LCD display shows tou the battery percentage is a great addition to the design in stead of the 4 dot light on others. I really really love the display on this one. - small, compact case and the earbud is fit perfectly in my ear. It comes with many different size of rubber cushion so you can swap to the one the fit you the best. I wear this over 4 hrs almost everyday and it hasnt hurt my ear a bit. Fit snugly and wont fall of while Im walking/jogging. - USB type C charger, which is very common these day. - Water resistant is a plus. Im jogging under the rain and this still works perfectly - the bluetooth range is super. I could get really far from my phone without losing connection. In conclusion, once again, if you are looking for your first pair of afforable earbud, or if you looking for an extra one to use without worrying about losing/breaking it while working or exercising, i highly recommend this product. You will not disappoint.

I have always loved TOZO headphones and this model is no exception. Very good sound quality, improved call quality (with respect to TOZO T6), perfect fit and water and sweat resistant for those intense workouts. The battery life is very good and there;s a battery indicator on the charging box. All in all a very good option to consider for daily use.

These headphones get the job done. Sound is clear and beautiful. I love all the TOZO products that I own. These do not disappoint.

These earbuds sound great for the price they are currently selling for. The bass doesnt overtake the treble, and the fit is also great. My iPhone had no problems syncing with them but the wireless charger Im using doesnt charge them as quickly as I would like.
