Sound Quality – The sound quality on those is by far one of the best from the ones have I have tried in the past. They deliver a good equilibrium between both the audio and the bass when listening to music, I am also a fan of using the NC9 whilst on a call. The audio of the other person speaking just sounds better with the outside world not interfering like using your phone speakers (due to the ANC feature included).

Build Quality – The way that the TOZO NC9 earbuds are made in is very clean. The earbud case is shaped in a way where it fits in the pockets easily and never gave me trouble using it whatsoever. the earbuds themselves are very snuggly when fitting inside the ear, also the magnets that attach the earbuds to the case are pretty neat, they just snap very easily and you don’t have to worry about them being in the case and not charging. Speaking of magnets, the case opens and closes a bit differently than the Airpods, they have this mechanism where you have to hold them up and they will stay, kind of like a door and not a switch, but still the build quality is amazing on them and I am very satisfied.

Pairing & Battery Life – I realized that pairing these earbuds are extremely easy, you just scan for Bluetooth devices and make sure that they are not connected to anything, then they will show up, click on them and they will pair just like so. Also the battery life is amazing. I use them for 3 continuous hours and switching through the modes with no battery problems whatsoever, and of course just around 30 minutes is all it takes to fully charge the earbuds from the case. I never faced any problems with the battery or pairing.

Earbud Modes:
Whilst using the NC9 earbuds, I have realized that I has three complete modes and each one has its own setting and a perfect time to when to use.

Active Noise Cancellation(ANC) – The active noise cancellation is incredible. I usually go on the bus to head over to University, so turning on ANC helps me by cancelling out the engine noise, some people talking next to me, and of course, any ambient noises. This helps me out a lot since I would love to listen to music without being interrupted by an outside conversation or just the sound of vehicles. Even if you aren’t a fan of ANC, you can just tap your left earbud and it will turn off ANC mode. Overall, an amazing mode for people who are trying to listen to a call in a crowded area or just a noisy place like in public transportation.

Transparency Mode – The transparency mode is extremely useful to me in its own situations. I usually love to turn this mode on when I am relaxing at my home, the music is loud enough to just cut off the audio from the outside of my room and it also helps incase someone in the house called for me to come. I can still hear people from the outside, just that now, it is much more easier and I don’t see a need to take them off whenever I need to understand what someone is trying to say to me. Overall, very useful in its own situations and when you do not mind the noises from outside.

Final Review:
In my opinion, these earbuds are fantastic for someone who has a 50$ budget and is looking to get into the world of “Noise Cancelling Earbuds” out there. The sound quality is high enough to compete with top brands, the build quality is fantastic, and the earbud modes are done pretty well. I give them a 5/5 since I see no flaws with them and would recommend anyone who is interested to give them a try.

The connected to my Samsung S24 with no problem and so far have not dropped out. It will take some time to determine charge time, charging speed and overall quality. I’ll add a comment abut that in a few weeks. So far I am impressed with the quality, they appear to be well built. It would be nice if there was checkering on the body for grip. If one has twitchy fingers (I do) they can go quite a distance after slipping out of one’s grip.

Overall I am very pleased with these earbuds.. Oh, yes, another positive. They fit snugly enough that they can be worn under hearing protectors.

There has been little chance to try the noise canceling feature, but it seems to work quire well. At least for the human voice. My dear wife had to use her full voice from six or seven feet away to get my attention while this was being written. I’ll see how effective it is with noise a couple days from now then it’s time to mow the lawn.

One caveat – to get the sonic best using an cup that completely plugs your ear is essential. A decent assortment of cup sizes comes with the earbuds, and it may take a little fiddling to find the set that fits your ear. It’s well worth the time to get the right fit.

The build quality is incredible; The matte black finish of the earbuds and case looks excellent, and the ergonomic design seems to be the best design amongst the Tozo earbuds. Like IT FEELS GREAT IN MY EAR. The T12 always felt a little bulky in my ear, but the NC9 feels it was made perfectly for my ear. Though, I have to admit it does feel a bit weird in my hand. I might just be used to the T12, or I just might be holding it awkwardly but, when I’m holding an NC9 earbud and trying my best not to press the touchpad area, I feel afraid I’m going to drop it. It’s because there’s minimal surface area on the side of the touchpad area to hold on to (but that’s honestly such a small thing).
Surprisingly, the noise-cancellation feature is REALLY GOOD. It’s not perfect, as no noise-canceling product is 100%, but like, it’s pretty good. And I mean it’s better than some noise-canceling headphones from competing brands that have worked on noise-canceling products for years (specifically the one that’s known for making lamps *cough* Taotronics *cough*). Low-end frequency white noises are reduced a lot, and voices are cut at a decent amount. Between that and anything you might be playing, it makes it that much easier to have uninterrupted experiences. The transparency mode is also pretty cool, but I don’t think it makes it entirely transparent. Much of the sound around you is still blocked by you just having earbuds in, but it does boost the voices around you slightly (And allow you to hear white noise again). But most voices are still a bit muffled.
The connection of the earbuds only got better. For one, it connects to my phone pretty fast, but the speed that the earbuds connect to each other is CRAZY. I mean, if I have one earbud in its case and I’m listening to music with the other earbud, if I take the earbud out of its case, it would connect to the other and start playing music FASTER than I could put it in my ear.
Now, this is where I start to have an issue with these earbuds. As I’ve already mentioned before, I think the sound quality, though superior to the T6, lacks in comparison to the T12. However, the sound quality is not my only issue as you may notice, I haven’t even mentioned anything regarding the case. And that’s because though I really enjoy the external design of this case, I think it lacks functionality. It’s a great design that feels more solid and compact and any of the Tozo earbuds while being really unique and beautiful. I like it being rounder and smaller than the T12 case, yet, having its own unique design compared to the T6 (which looked like black Airpods). With a matte finish, that has the TOZO brand on top, and a glossy ring for contrast- the outward of this case looks outright awesome.
Nonetheless, that is where the fantastic details end with the case of the NC9. I might be spoiled at this point from all the other Tozo products, but I was sincerely disappointed to learn that this model DOES NOT have wireless charging. I was also sad to see that we went back to using dots as our sole way of determining the battery life of the case, which I am not a fan of. There’s also no way to know the battery life of the earbuds.

SUMMARY
Overall, it’s a good product. When it comes to the earbuds itself, they’re great, the design is awesome, and personally my favorite design amongst the Tozo earbuds since it’s as stylish and comfortable as ever. The connection process has also become more seamless than ever, being faster than all previous Tozo earbuds. The noise cancellation and transparency mode are also amazing new features that although they’re not perfect, they are still convenient, and I hope it becomes a standard for future products that they improve on. However, while the sound quality is better than that of the T6, it falls far short of the T12. The case is also underwhelming as it no longer has wireless charging and has stepped back down to just using dots as the way to indicate battery life. There’s also no IPX rating for these earbuds, which is dually disappointing. All in all, if battery indicators aren’t a deal breaker for you and wireless charging, waterproof rating and minor differences in sound don’t matter to you as much, I would recommend these earbuds. I personally use these now as my preferred method of watching videos, And YouTube on my phone, as the portable noise cancellation is really awesome.
