Firstly, the design of the buds themselves is very compact. They sit almost flush with the outside of the ear and are shaped so that, for me, they don't really create any notable pressure points or discomfort. They come with different sizes of silicone tips so that anyone should be able to find a secure fit. Once an adequate seal is obtained, I've found that the passive noise cancellation is adequate for most tasks. I've mowed the lawn with these in and it reduces the volume by a surprising amount. Of course, there is no active noise cancellation, so they won't completely eliminate droning background noise. The plus side is that, unlike with ANC earbuds/headphones, one does not experience that "plugged ear" sensation that those can sometimes cause.
The case is fairly straightforward, but it feels sturdy and it does a good job of keeping the earbuds secure and charged when not in use. I really love that TOZO included the front display on these. Far too many manufacturers use a minimalistic system of differently colored lights to indicate battery status and it's often unintuitive. With these, you get a numeric display of the overall charge and individual indicators of each earbud's battery levels. The case also supports wireless charging which is a huge plus for me. It's ridiculous how many manufacturers don't consider that people who want totally wireless earbuds might also value wireless charging of their devices. Many premium brands don't support this on models that sell for much more. My only nitpicks with the case is that the magnets holding the earbuds can be quite strong and, due to their minimalistic shape, there are few places to get a good grip on them to remove them. Additionally, I do wish the lid wasn't clear since it tends to show scratches quite easily, but that's purely a stylistic complaint.
Now for the most important part - sound quality. I've never liked the term "audiophile," but it does come up frequently when people describe me. I have quite an extensive setup at my PC listening station and I've collected many headphones that cost more than a monthly mortgage payment. Some days, I put these earbuds in and I wonder if all the time, effort, and money was worth it. That's a pretty massive oversimplification, but I want to illustrate how surprised I was. Should you actually expect the same sound quality as a set of $1000 headphones attached to a dedicated audio stack? Absolutely not. However, there's a tool for every job and these check an absurd amount of boxes for the price. They're great all-rounders and, most of all, they're convenient. There's a saying in photography that goes "the best camera is the one that you have with you." I feel that the same is true in this instance. It doesn't matter how good your audio setup at home is if it's not portable when you need it to be. As for the sound signature of these earbuds, I'd say that "fun" is probably the most succinct description. They've put some emphasis on bass and can sound a bit boomy at times but manage to retain enough clarity that you can hear most of the details. The very top end can seem a bit blunted occasionally, but I've never found it to be an issue that got in the way of me enjoying the music.
Overall, it seems like TOZO set out to design an earbud that satisfied the preferences for a majority of casual listening situations and they've done exactly that. I can't recommend these enough!
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 can't 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 couldn't tell any difference in sound quality from using my Galaxy S22's 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 haven't 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 haven't 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 don't really know what they mean but definitely not worth taking off a star for that.
Top reviews from other countries

I have yet to drain the battery life fully, I usually listen to them at around 80% volume and they’ve lasted me 5 hours on my longest listening session and still had 30% left.
The case has a display which shows the case battery life in a numeric format and shows each of the earbuds with battery indicators.
Sound
The sound quality for music is great, I’m no audiophile, however there is a good balance of bass and voice (I like my music bass heavy). They give a clear sound and I’ve able to hear the sound separation of various instruments in the tracks. I’ve used these earphones for RnB music and to listen to Podcasts and Audiobooks and they’ve managed all of them very well.
Call Noise Cancellation
The main use for these earbuds will be for Microsoft Teams meetings, the microphone for sound quality is excellent and they block out nearly all background noise. I’m able to hear voices clearly and there is no lag. The connection is very stable and gives me no worries using them into the future.
Comfort and Design
The earbud’s are rated as IPX7 water and sweat resistant which is good for when I’m working it. They are slightly bigger than the Apple AirPods Pro’s I’ve been using but just as comfortable.
They don’t have active noise cancellation; however, they do an in-ear design which blocks out most of the outside noise when playing music (which is good enough on most occasions)
Ease of Use
As with most earbuds, you can use taps on them to various things such as answer calls, play and pause music and even turn the volume up and down. Once you’ve gotten used to what the taps it’s very intuitive and has become my primary way of answering calls.
Price and Packaging
I got these earbuds during a boxing day sale, they are well worth the price with all the features they have packed into them.
Point of Note
Spend a few moments to find the correct size of ear-tip for the best fit which affects sound quality and comfort. The eartip’s are a little fiddly to swap around but once you’ve got the right size, you most likely won’t need to swap them around again.

Yes, they don't have active noice cancelling, but most ear buds handle noise cancellation by simply fitting well within the ear canal. That's where these are. The low profile tri-shape make these simply a great fit for most. Certainly in my kids ear who is smaller than me. They fit us both great with the included ear tips.
A great bonus with this pair is the inclusion of an app you can use on your phone to control the sound. Wow! That functionality is usually reserved for the more expensive ranges. Tozo have done a marvelous job here of getting an app in at this price point. And it works really well. Most Android EQ apps lower the overall volume when using such apps. This on integrates directly with the ear buds and just change the EQ setting on them with no issues.
Pro's:
- Stunning fit
- Tiny case that shows charge
- App
- intuitive touch controls
Con's:
- No active noise cancellation (really NOT an issue honestly!)
Well done again Tozo. What a great product.

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 , water-resistant so you can use them in the gym if you want..
A big brand good pair is of hundreds.. These are very affordable...
So if you're like me, just an ocasional user and don't want to spend on some expensive brand than these are for you.

Start with the case - slender, charges both wireless and through USB-C, and shows battery level too - 10/10.
The earphones are comfortable and as usual come with different sizes for earpiece. I always need to swap out the default to a smaller size, and I was able to get one that fit.
Controls are easy to get the hang of too - there's no button just a "touch" area on the outside part of each earbud, and you can control playback, volume, accept calls etc by using a different pattern of taps/holds - I don't mess around with those too much so usually I just use single taps to pause/play, and occasionally holding to control volume. The part I like the most about these is that unlike some other touch control earbuds these don't trigger TOO easily - so if I'm only adjusting them from the edge it doesn't register that as some kind of input, which used to annoy me in other earbuds I've tried.
No complaints about the sound quality - it's very clear and balanced, noise cancellation is noticeable too.
All in all, would recommend.

These were an emergency purchase as I went to stay with relatives for Christmas and forgot to pack any headphones. Thanks to Prime Delivery these arrived 10pm same day I ordered (thank you Amazon Prime!). Over the last few days I have used these to watch movies, listen to music, speak on the phone and I also used them on a Chromebook for a Skype call with my French tutor. The people I spoke to said they could hear me really clearly so these live up to Tozo's claim of great Call Noise Reduction. I love the LCD on the front of the case, just lift the lid to see how much battery is left in each individual earbud as well as in the case.
