Not bad at all! I bought these to try out and they are pretty good to my surprise. The sound quality is not bad, and the noice cancelling feature is pretty good! I would say they are similar to airpods if you are looking for a cheaper alternative and I would definitely recommend them!

I got these since I lost my old ones. These sound and fit perfect. They are officially my gym earphones now.

I love these TOZO Crystal Bud earbuds. I have a real problem keeping most earbuds in my ears. No matter how I have tried most earbuds will slip and fall out of my ears after a short amount of time if Im moving around. Especially if I am just chewing. My ears are small and shallow. These are the first earbuds when I have no problem with. Walking around, bouncing up and down stairs or just lying around the house. They stay put, and thats say a very big amount with my ears. Id love these earbuds if that was the only good thing. However, the also give me just about the best battery life of any earbud brand. Of course, that seems to be a thing with TOZO. Where much more expensive brands get upwards of three to four hours on a charge, TOZOs give me seven to nine hours of continuous listening. Music, videos and movies. all average about eight hours. And they only take about one and a half hours to fully recharge! Ive tried many of the brands that the kids all love these days. And for twice the price youd think theyd at least get six hours, but no. I had to find out the hard way that a seemingly cheap earbud brand provides real long lasting listening time. And thats still not all. The TOZOs also have great sound. Rich bass in music and very clear voice when listening to videos and movies. The Crystal Buds also work with the TOZO app on my Android phone. So I can adjust the boost levels with a customizable equalizer. This particular set of TOZO buds do not have noise cancellation, but thats not problem for me since I only use these around the house when listening to podcasts, music and the occasional movie. So these really are the best of all the earbuds Ive tried to date. And at a very reasonable price, which makes them a win-win-win!

This is my 5th pair of TOZO earbuds-- one for each child. T9 and T12s. These Crystal are very sharp and have great sound. I would highly recommend for anyone that dont want to shell out $100s for high end devices.

Cuando busque el producto, tenía varias alternativas de la marca, sin embargo la estética siempre me pareció la misma en los audífonos; cuando vi estos me llamaron inmediatamente la atención por su llamativo diseño, la tapa transparente no la he visto en ninguna otra marca, así como los indicadores de carga de cada audífono en el estuche, otro aspecto que me llamo la atención fue que al interior del estuche de carga ya no aparecen imanes a la vista, lo que permite que estos se suelten por consiguiente se extravíen , con la perdida irremediable del audífono y de la inversión. El sonido es de lo mejor y la cancelación de ruido es muy útil en espacios abiertos, lo que permite el uso de manera cómoda, es muy útil ver el nivel de carga en el estuche, cosa que la mayoría no posee. La APP para la administración de los audífonos es intuitiva y tiene opciones de configuración interesantes y que se adaptan a mis necesidades y preferencias, como por ejemplo, el escuchar música que tiene preinstalada, así como la configuración de un ecualizador que puedes personalizar y guardar En términos generales estoy satisfecho con mi compra.

I’ll start by stating that I have had a few different TOZO earbuds. T10s, T6s, A1s, and now the crystals. These just arrived this morning so this is only preliminary, but I am expecting them to last just as well as my others! I prefer X8 waterproof earbuds due to fishing with them, so I had to give these a try. Connection was a breeze as always, nice that I already know what size silicone fits my ears best. Before using the app, I wanted to test the standard EQ. Nothing mind blowing, I have a pair of audiophile level earbuds for that experience. But I tested some of the EQs in the app until I found my personal favorite, and then from there I adjusted it to be even better and saved. This definitely takes the sound to the next level! The app also showed there was an update, takes some time so do it when you’re not needing to use your phone for a little. These buds looks pretty sleek compared to their other designs, and man do they feel comfy and fit my ears well. Plus, they are super low-profile, even more so than my already tiny A1s! I think I can actually wear these, comfortably, under a full face helmet! Super excited to see how good these are long term, have yet to test the call noise cancellation.

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 love these earbuds! This is my second pair of Tozo products and I haven’t been disappointed yet! I love the digital case and they sound amazing. They’re easy to work too and I love using them for phone calls. Get yourself some. You won’t be disappointed.

The sound is fantastic. Very comfortable. Battery life is very good. Easy to set up and use. I strongly recommend this product. Love it!

I am a huge fan of TOZO earbuds since the T6. I’ve bought several of their earbuds and enjoyed them all. These however are my absolute favorite! The shape of the earbud is perfect and comfortable to fit into my small ears. They seriously are the best feeling earbuds! But that’s not all that’s great about them. The sound quality is absolutely amazing! You have to listen to music in these! I can’t believe that they can make such great sound out of such a compact earbud. The case is soo sleek and very cool also. I love the crystal clear top and how the charging percentage lights up the number on the outside of the case. Such an amazing design! Just when I thought TOZO couldn’t get any better, they come up with this!
