They are very comfortable and dont fall off when running! Wich is one of my main complaints with many earbuds. Sound quality is good and battery life is great. Another thing that I noticed its that it doesnt really bother having them in the ear for longer periods of time like others Ive tried. Overall, Im impressed.

Great product, good support and easy to use.

These are my 15th pair of TOZO earbuds - mostly for my own use, but a handful as gifts. I have been wowed by the sound quality at a budget price from the start. But these Crystal Buds take clear, crisp and full to a whole new level. Super impressive and highly recommended.

Sound quality and noise cancelling are great! I especially like that you can see the charging status of each headphone on the display.

I am truly impressed with these new earbuds from Tozo. The digital display showing case battery life is definitely a nice feature. The sound quality is really good with nice range and very good bass. The noise cancelling function is a must. I even use these while doing yard work and it reduces the noise of power equipment to a bare minimum. I highly recommend these - you wont be disappointed!

Nice little set of buds. Feel great in the ear. Great sound and battery life! The case is sleek, and like that you can easily see the battery life on the case.

This pair was a little more fussy about pairing than all of the others (T10, T12, T6, NC2 that I own). The earbuds can be adjusted with the new app that you can download. You can adjust the treble, bass and other sounds. The fit is good, not too small or too large on the outside of your ear.

Ever since Bluetooth earbuds became commonplace, Ive used them pretty much constantly throughout my days to listen to music while I work. Generally Ive gone for the cheaper end of the range, buying whichever brand was less than $20 or so. I do appreciate good audio quality, but for some reason I assumed that earbuds didnt have the quality range that speakers or headphones have, and that one pair was as good as the next if you werent willing to spend $150+ on audiophile models. Boy, was I wrong! For only about twice what bottom-dollar Bluetooth earbuds cost, these sound *way* better. Its not even close. Theres actually solid bass, a bit of a discernible soundstage (though still far short of speakers), and some detail in instruments and voices. Entry-level buds can sound OK, but they lack any real presence, like these have. There are several sizes of rubber tips included, but I usually ignore those and use foam tips instead. Those completely seal your ear canals (much like Hearos or other foam earplugs like you should be wearing to concerts) to block out environmental sound and really put all of your focus into the music, while highlighting the strength of the bass. If there are two nitpicks, one would be that the app that allows you to choose from EQ presets *only* allows you to choose from presets - it doesnt actually let you adjust the frequency response to craft your own sound. The other is similar, in that the EQ presets available seem to be a little bit heavy-handed in how they affect the sound. I like the R&B preset the most since it boosts both bass and treble, but at the same time it leaves the midrange kind of muddy and subdued. Im not an audiophile, and these are not audiophile-grade earbuds - but for the price, I cant imagine finding better sound anywhere out of reasonably-priced earbuds. Theyre in a league above entry-level stuff, for sure. Battery life is great. I can get through a full day without running out of juice, and if I still want to listen in the evening, I can just charge them for 30 minutes or so and get a few more hours out of them. Also a great feature that the charging/storage case will also charge them up to 4 times using its onboard battery - means you can use these while traveling or in other situations where you might not encounter a wall outlet for a few days.

These are well worth it at the price point (Could buy 4-5 pairs for the whole family and still be less than one pair of ApplePro). Sound and noise cancellation are good. The newly designed case is nice with the display on remaining charge.
