You can see how much battery life is left in the case and the headphones themselves. The tips of the headphones can be changed for a better fit

I had them for a few days and worked and sounded great but the case felt cheap and flimsy which I was going to live with. But then I dropped it (on carpet) and somehow one of the earbuds popped out when the lid flapped open and shut again, which I did not eve realize had happened. Well my dog found it before I did and so goodbye crystal buds... Just seems like you should be able to drop the case from 3 feet onto thick carpet without the earbuds flying out of it.

The TOZO Crystal Buds “True Wireless Stereo” are the best in class with great stereo-quality sound. This model has got a smart LED digital display that can show the battery levels. The new transparent ergonomic design looks very catchy and stylish. The smart AI noise reduction is amazing which helps with the best sound quality during the calls. Overall this is a very good cost-effective product.

I have a few tozo earbud products. These earbuds fit nicely in the ear, great sound and battery life seems to be good. I like the display on the charger (percent charged); that is handy. Only downside is the earbuds are bit difficult to get put of the charger unit. They are tricky to grab sometimes.

I love Tozo products! I recently purchased the Crystal buds, and theyre a great! The sound quality, noise cancelation, and comfortablity are all great quality. I would recommend to get this product to anyone wanting a high quality product for a cheaper cost.

Very comfortable fit and excellent sound quality. I use them while working out on a Bowflex Max Trainer. Despite lots of movement and sweat, these buds stay in place. They are a bargain compared to the high-priced buds Ive had in the past. The sound is just as good and the fit is even better. Recommended.

TOZO always makes very reliable and affordable earbuds and these crystal buds didn’t disappoint me. Clear lids look cool and the level of charging was displayed on LED digital screens which is very convenient. Wireless charging was really a plus for me and difficult to find at this price tag. Fully charged earbuds lasted for about 9 hours with 50% voice level. It has an IPX7 waterproof rating. I havent tried it in the shower, but these were great for outdoor activities and working out with heavy sweat and light rain. The sound quality was quite good and impressed me quite a lot. I think you can customize the EQ via app, but for me the original sound was totally fine for music and phone calls. Only cons I experienced was the noise canceling during commute by public transportation. Overall, I think these earbuds were really great for the price, especially if you are looking for a nice pair of earbuds for exercise and outdoor activities.

These are even better than the previous version , they fit my tiny ears comfortably. I also like the digital display on the case that clearly tells the charge percentage. Im happy with these!

This is my 2nd pair of TOZO buds and while I appreciate the noise cancellation options of my first set for working at a coffee shop for example, these work great for phone calls, mid-range audio and outdoor exercise. As usual with TOZO, the Bluetooth connection is great, connection works at quite a distance from your phone - I was still hearing audio in the locker room when I left my phone on a gym equipment piece 2 rooms away. The fit is great as it is molded to the contours of a human ear - what a concept - thanks for getting that right TOZO. The charging case has a firm magnetic lock, its easy to put them in to ensure they charge and best of all - digital readout of the charge left per earbud, very nice. My first set had a bad left earbud but the replacement set is working great so review based on the replacement set.

These ear buds are absolutely the best Ive owned. They fit very nicely, the touch controls are intuitive, and the case design is surprisingly sturdy. The crystal top is a nice touch. The pros: Usb-c charging!! This was a major requirement when I was looking for a pair of earbuds to purchase. I couldnt tell for certain if they charged with type c or microUSB, luckily it was exactly what I wanted. High quality and great fit. I dont like earbuds with a stem, and I dont like the Apple shape, which some companies try to emulate. These are the version with no stem, but they also have a neat shape that fits in the ear nicely, and they dont fall out that easily. The case is built very nicely, and its not too big either. They have wonderful sound quality. I dont know if theyre adjustable or if theres an app; while I write this I cant remember if the listing included it and I dont use it (yet?) If there is one. Out of the box, the base is nice but not too overwhelming, its clear and not muffled, and they can get pretty loud without needing to turn them up very far. Edited to add: there is an app. You can only adjust the buds if theyre both connected to your device. The app is pretty easy to use and I believe its just called TOZO. The cons: The case doesnt hold a charge very long. Now, the earbuds themselves do and I think each one charges twice before the case dies. Its not a huge deal because of how long the buds themselves stay charged, but if you do need the case to last a while, keep this in mind. The screen on the front of the case keeps track of the battery life of each earbud and the cases battery and updates as you charge it, which is nice. The alert sounds the buds make are a little confusing. Dont get me wrong, the sounds are actually not bad, they just confused me a bit when I first got them. Out of the box, one earbud was dead. When I paired it (which was easy btw), it kept alerting me to that. I wasnt sure what the alert meant and at first that bud wouldnt connect. Admittedly, not sure why that happened. I unpaired the earbuds and let them pair while still in the case, which I highly suggest you do the first time as well. This time it worked, but the alert kept sounding. It eventually dawned on me that the earbud was probably just dying, so I put it in the case and all was well. They dont speak, each alert is melodic and not startling. Just keep in mind that your earbuds arent broken out of the box, they might just be dead. (Do not forget to peel the blue tape off the connectors). Overall, an amazing set of earbuds. TOZO seems to deliver quality earbuds every time, and the price is incredibly reasonable. A contender in the ring with the expensive ones for sure.
