I have only owned these earphones for one day (purchased them for $27 on a Lightning Deal), so this "review" is really just my first impressions. I'll update this review if any issues come up that make me reconsider my feelings on IEMs. I am not a hardcore audiophile, but I do appreciate quality headphones and earphones. I'll talk first about my intial impression of the build quality, set up and bluetooth performance and sound quality.The build quality on these Tozo T2 is pretty darn good. The case is well made and very solidly assembled. I have no doubt it can handle a good drop from your pocket onto concrete. I also don't doubt Tozo's claim that the case has an IPX8 rating (and I usually take those types of claims from chinese manufacturers with huge grains of salt). The micro USB port on the case is covered by a rubber seal and the case shuts firmly and is held in place by three heavy earth magnets. The same type of magnets are also used to hold the earbuds in the case when they are charging. They aren't going to rattle loose or pop out unless you want them to come out. The earbuds are also really well made. They have a very solid feel and the plastic doesn't feel cheap at all. Because of these are TWB earphones, they are not the lightest I have used though and, overall, they feel heavier than typical wired bluetooth IEMs. This isn't really a big deal, since I had no issue using them through my workout at the gym this morning, including HIIT session on the treadmill and an intense weight training session. I also tested the Tozo's claims of IPX8 water resistance rating by giving them a wash in the sink and using them in the shower. The held up just fine and it was nice to be able to listen to my tunes during a shower!!! This capability makes these earphones perfect for the beach or pool, where you wouldn't risk more expensive and/or delicate earphones.As for the feature set, I really like the fact that the case for these earphones can be charged using a qi wireless charger. I could have lived with the micro USB, but this just makes the process of charging the case (and earphones) so much easier!! On the other hand, these phones have one button on each bud that controls your phone. Click once and it will pause your music. Click again and the music will restart. Those are only media functions these buttons serve. Other than that, the buttons are used for accepting, rejecting or hanging up on phone calls. It would have been nice if you could use them to change music tracks and control the volume. Other earphones in this price range ($40 list price) have these capabilities, but they don't have the waterproof rating or the wireless charging capability. So, you have to choose what is more important to you.As for bluetooth connectivity, set up is as easy as everyone claims. Take the IEMs out the case, they go into pairing mode and connect to each other. They show up as available on your phone's bluetooth menu, and you click on the right earphone--that's it. The automatically turn on and connect to the phone when the IEMs are removed from the case. This makes them very simple and easy to use. Due to their size (although they are not large by any means), it does take a little longer to get them comfortably situated in your ear than most wired IEMs (bluetooth or otherwise). This is probably true for most TWB IEMs (with a few exceptions). Once situated, they do stay where they are suppose to, although you need to make sure you are using the correct sized earphone tips. The medium sized silicone tips that came pre-installed on the earphones fit me just fine and held the earphones firmly in place. However, I am currently using a pair a medium sized comply foam tips (they did not come with the earphones), since they are comfortable and hold the earphone securely in place (and create a better seal than silicon tips IMO).Before I get into sound quality, this is an element that is very subjective. Although I am not a hardcore audiophile, I care about sound quality and have invested in some well respected headphones and IEMs (Grado S80s, Audio Technica ATH-M50X, Shure SE425, Tin Audio T2, KZ AOS10 etc).. I tend to like a earphones that have a fairly neutral sound, but are capable of generating tight controlled base (which can be brought out using the equalizer on your phone or tablet). These are NOT neutral sounding earphones. In fact, it sounds to me as if Tozo designed these earphones with a fixed EQ setting that overly emphasizes bass (particularly in the lower and mid range). This causes the bass to bleed over into the mids. If you ever listened to a 5.1 surround sound system where the subwoofer's crossover is set too high and at too high of a volume (creating that booming/overwhelming sound), these earphones have that effect. There is also some sibalence in these earphones--far from the worst I heard, but it is definitely present (especially for female vocals). These are earphones that are tuned for bassheads, but the 8mm drivers used by Tozo don't have the chops to really deliver clean quality bass. Tozo would have been better off not trying to put a fixed EQ setting in these earphones and left them with a balanced setting, which anyone can tweak to their taste using the EQ on their phone.In short, these are NOT the best sounding earphones I have ever heard. The sound quality is on par with a set of wired Philips Extra Bass headphones that you can buy for $15 at CVS or Rite Aid (which is they type of earphone that most people use). What makes them special is the fact that for $39 ($27 if you got them on a lightening deal), ,these earphones are rugged TWB earphones that are waterproof, come with a waterproof case that also serves as wireless charging base, and is, itself, capable of being charged with a Qi wireless charger. They aren't going to replace my Shure SE425, but they will compete with my superior sounding Tin Audio T2 (which I have connected via an MMCX Fiio bluetooth cable) for time at the gym and certainly during the summer at the beach and pool. I don't have much experience with other TWB earphones, but it doesn't seem like Tozo's competitors are offering anything significantly better in the sub-$50 range--so this is about as good as it gets for now (I am sure things will be much different in a year or two).

TLDR; For the price and comfort, well worth it. Love how it has different sized earbud pieces for comfort and fit. It can fit my husbands large ears and my small ones with a change of the earbud pads. Its very clear and crisp in terms of sound and set up was easy. You can also use one at a time, instead of both, which is nice. Plus water resistant while working out is VERY nice for working out or pool side. Also, there is wireless charging but I often opt for charging with a cable.Honestly, I was afraid to get a wireless bluetooth headphone, given how often I misplaced things, but given my new phone had no AUX plug in, I had no choice but to get one. And there were SO many choices, which can be a little overwhelming especially for someone that had no idea what features to look out or go for. After some research, I've come across these to give them a try. With the reviews and the price, I thought this was my best bet. Not just that but it also came with their own warranty. Honestly, I have no regrets. I've tried other ones after but I always go back to these.I love how it comes along a small bag with various ear bud pieces for your comfort. I've seen others that didn't have such since they have it as one-size-fit-all and believe me, one size does NOT fit all. My husband is able to change into the larger earbud pads for his ear while he uses it. And when I was able to snatch them back, I was able to change it back to the smaller ones for mine. Well, that is, until my husband took my first pair and I had to order another pair for myself. It wasn't long before my kids started to take interest and use it for themselves as well, which is nice given I can use one and one of them can use the others and we can both listen to music be it at the house, long car trips, or poolside.The sound, least to me, is very clear and crisp. I don't have it very loud, often putting it on the lowest setting, and can hear it quite well. Even when not in my ear, on the low setting, you can't really hear the music until you put it back in your ear again. I hadn't tested it on the higher volumes but I doubt anyone really needs to unless you're in a very loud area or just want to rattle your eardrums. Noise cancellation is on par given the ear buds that fit in your ear can block most of the sounds from the outside. I had even used it in meetings and they worked a little too well on not being able to hear anything other than what you have playing through the earbuds. Just note, after so many hours your ear will feel a little damp on the inside due to lack of air circulation. (Think of it like having a bandaid over a cut and it not being able to scab because it locks in the moisture that way) I have also been guilty on wearing a pair at night(I recommend not doing this for safety issues) and thankfully had no issues with them. They were comfortable enough through the night.The battery life is rather good for something so small. For me, it lasts about a whole work day so I can pop one pair while working for 5-8 hours, then pop in the other pair to listen at home while the first one charges. Charging it is amazing as well. Just pop the things back in the case(which clicks in place because of magnets) and it'll charge on its own, so long as you precharged the case. So, if you're on the go a lot this is SUPER handy. I read you can charge it wirelessly but I never tested this since I just plug it into a charger myself since anything I put on a wireless charger, near the bed, gets knocked over and off.Its quite resilient on being water resistant. I'm not sure on it being water proof since I never fully submerged it underwater for a set amount of time but with with sweating and being splashed at with water, its still working like new. If they ever do go underwater, I'll see what happens then but hopefully I don't get the chance but if you have pets and kids, especially near and around the pool, you never know.Overall, I love these little guys and so does the rest of my family from my 6 year old to my husband. Give them a try if you're in the market for them.Unfortunately, my (Human)family weren't the only ones that enjoyed it. Apparently my dog also liked it so much that it ate my right ear piece. I only found this out when I found my right piece missing, thinking the kids took it, only to find it when cleaning after the small dog after he did his business... Although I have the protection plan, through Amazon, it did say I have the manufacturer's warranty still in place so I am in contact to see if what I can do about this.

I'm one of the very, very few people who cannot use the apple air pods. No matter how hard I try, they fall out of my ear in less than a minute. I thought I would try a different brand, and when I put these in my ear, they fell out within seconds. I was about to give up, pack up the box, and send it back, but I decided to check out the instruction manual in case i was doing something wrong. I’m so happy I did. Turns out there were 4 sizes of plastic ear caps included with the earbuds. On my third try, the second smallest ones, I felt how i imagine Cinderella felt when she tried on the glass slipper. They were perfect and no matter how much I jumped up and down or shook my head, they stayed in place!The quality of sound is impeccable, nice highs and lows, with a decent amount of bass. Once I found the right match, the fit was extremely comfortable.I love these headphones, they have already changed my life for the better!
