No complaints with these - I like the fact that theyre water proof

Like most tozo products they actually work well and at an affordable price.

Unsure if Crystal in the name is because of the clear cover, but it really describes the clarity of these earbuds. These have a completely different sound profile from those in the Tozo line that Ive used before -- theyre much more open & spacious on the high end with zero boominess on the bottom. Clarity of sound appears to be Tozos focus with these earbuds, which I really appreciate. The case is among the smallest, but what I REALLY like is that they fit small ears, without anything hanging out. Zero ear fatigue wearing these, thank you Tozo! Ive had to give away other models because they didnt fit (nothing negative against the other models), but these fit great.

Have been using these ear buds for a few weeks. They pair quickly. Charging block shows % charge. Tozo app is great to adjust equalizer. Good sound. Nice quality. Another great Tozo product. Would buy again.

Pros: These like other Tozo products have really nice fidelity. I have never been disappointed but sound quality with any of their products. The ear buds have several ear cushions to mix and match your perfect fit but you will notice the buds are extremely lightweight without feeling cheap which is a difficult balance. The case with the percentage battery is great, ledgible and a very useful feature. The case itself is nice with the exception of the plastic top which feels a little flimsy. Cons: As mentioned, the case top feels a bit flimsy as a translucent plastic. The app is great and I also have the NC7 which I have never had an issue with connecting but the crystal buds had a couple of times that it would not connect to the app, not a huge deal but something to be aware of. It did connect fine the next use however. Overall, These are a great alternative to high end earbuds.

Update: After about 2 months, the right earbud has dropped in volume compared to the left. Followed reset procedure but it did not fix the problem. I only use one earbud at a time so they are still usable for me but for someone who uses both at once, this would be an issue. TOZO earbuds have been a good brand with good sound quality and great durability but I cannot recommend this model. Their other models Ive tested over the years have worked flawlessly and I would suggest their A-1 model instead of these, or T-10 if you are planning to use them in the shower. Original review below: Ive used five different models of TOZO earbuds for several years now and these Crystal Buds are the best Ive tried. I received them as part of a promotion. Sound quality is excellent and only sound professionals or enthusiasts will likely find anything to criticize. A single earbud battery lasted about 8 hours of continuous playback with one charge in my timed test but if you only use one ear, you can just take out the second one and then charge the first without bluetooth disconnecting or even pausing playback. So you can get several days of playback with a full charging case, depending on usage and volume. Price is great for what seems to basically be the equivalent of Google or Samsung earbuds. I just received these Crystal Buds and so cant speak of their longevity though in my experience, TOZO earbuds in general have been quite durable and long lasting (until I lose them). I only ever had one pair (A-1 model, not these Crystal Buds) that the charging prongs got a little worn. The A-1s still charge ok but need occasional prong polishing. Improvements Over Previous Versions: Microphone: Previous TOZO versions with a built in mic were nearly unusable for a phone call. In my testing with the Crystal Buds, I almost couldnt tell any difference in sound quality from using my Galaxy S22s built-in mic vs the mic on the earbuds, just slightly more tin-canny than usual phone call but still easy to communicate hands free. This is impressive since the phone mic is in front of your mouth but the earbud mic has to pick up ambient noise from the side of your head. Ear drum pressure: Previous TOZO versions would sometimes make a vacuum or high pressure and hurt your eardrum when inserted or when you pressed the button too hard but these seem to have fixed that problem and I havent experienced any pressure pain inserting or removing them. Water and button sensitivity: Previous TOZO versions were water resistant but their button was too sensitive. So when you would take a shower, previous versions would think you were holding the button down and turn the volume all the way up or down. They would also register any slight brush or repositioning as a button press and pause or start your music. The Crystal buds have a much less sensitive button that mostly only works when you actually want to push it and worked fine through a whole shower without pausing, though they did slip out of my ears when wet. I think that can be fixed by trying some of the larger tips they include but havent tried yet. Cons: The only thing I miss from previous versions is they changed the voice messages like low battery or Your headset is connected to different beeps and boops that you dont really know what they mean but definitely not worth taking off a star for that.

Over the last years I have bought several Tozos products and have become a fan! These crystal earbuds have great battery life and are quick and easy to charge. With the sleek charging case you can see how much charge is left which is great. The case is magnetic, looks nice and feels sturdy. The noise cancellation is good . Easy touch control for volume and skipping songs. The microphone for calls is great and very clear. To pair with your device is a breeze , and they automatically pause when you take them out. The sound quality is excellent for the price and they are also water-resistant which is a nice bonus. With all the great features, quality and ease of use and also being very affordable, these are a great buy and will not disappoint!

This is my 4th Tozo device. I like the digital display and the comfort fitting that the Tozo brand provides. Sound quality is also comparable to other brands. Will be purchasing more in the future. I use these daily at my Job and on the weekends in the shop.

Get the perfect fit with the multiple sizes of silicone ear pads. The sound is clear, losing a bit in the bass, but good sound from tiny devices. Charges quickly with long run time. Intuitive set up and use. Overall, Im very happy with these.

I like the shape of these new ear buds from Tozo and how they comfortably fit and stay in my ears. I own and have used few other Tozo earbuds and this is the first one that works with Tozos headphone app which provides fine control and settings, including equalizer function for the Crystal earbuds. I use them at work, sometimes all day long and never had any issues with battery. The storage case charges the ear buds with its battery pack and can be charged either wirelessly or with USB-C cable. It is a small case which you can easily carry in your tight jeans pockets. Sound quality with clear treble and relatively deep bass is on par with more expensive products. So, I recommend these earbuds if you are on a budget and would like to listen to your music and podcasts with crystal clear sound without worrying about connection issues or battery life.
