TOZO T12 Pro Wireless Earbuds Bluetooth Headphones with Qualcomm QCC3040 4 Mics CVC 8.0 Call Noise Cancelling and aptX Stereo Headset 2500mAh Wireless Charging Case IPX8 Waterproof Earphones Black

I purchased the T-12 Pro’s to replace a broken set of buds. I opted for the T12 Pro’s because of all their features, but most of all because they have the Qualcomm QCC3040 chip and larger speakers.RatingI would give 4.25 to 4.5 stars if I could. 1/2 star off due to no active noise canceling and does not interface with Tozo sound mixer app. But don't let that stop you from buying. These are really good buds that deliver first class sound/music for half (or more) the cost of competitors' buds.Life/UsageThese earbuds are advertised to have a long battery life. I have yet to have them come even close to needing to be recharged during daily use. I plan to use my T-12 Pro’s on an 8 hour flight next month. Let’s see what happens.Case (See photo below)The case is massive. The advertised picture might make the box appear to be a bit smaller than it is. IMHO, the “large” case is nothing short of amazing. 1st is the digital scale/meter. Then there is the indicator that lets you know the charging status. The case can be used to charge my cell phone, iPad, etc. Tozo advertises that the case is able to charge the buds for 170 hours of use. I would believe them. Behind a rubber cover (see Tozo image on website, the are behind the rubber waterproof cover in the rectangle below the blue light) you will find a USB-C and USB-A ports. Tozo advertises that the case can be charged wirelessly. I have not tried it because I prefer to use a cable.DesignI like the design over the “stem” style buds. There are two LED’s that let you know when they are bluetoothed to whatever device you are using. There is also a voice that says "bluetooth connected." I have not experienced any issues with them staying in my ears. The T-12 Pro’s also come with different size tips to fit your ears.SoundThe T-12 Pro’s DO NOT interface with the Tozo sound mixer app. They DO interface with the mixer/selector in my iPhone. They are not noise cancelling (this has yet to be an issue). For listening to music these Tozo’s are truly a great set of buds. I can listen to music with discernible bass and treble. The quality is better than my T-20’s, but these buds are almost 2x the price. I would compare the T12 Pro’s to buds costing 2x - 3x as much.FeaturesVolume, answer calls, change music tracks, etc., can all be changed by tapping the right or left bud. Blue / Red LED to confirm Bluetooth connection. The are allegedly waterproof, but I would never wear them while swimming or near water. Biggest bummer: no active noise canceling.Customer ServiceNothing short of amazing. If you happen to have a problem/issue a Tozo rep will be in contact with you w/in 24 hours.TozoThese were my 1st Tozo’s. Since then, I have purchased the T-20’s and T-1’s. Tozo offers great bugs at a great price.UPDATEI used my T-12 Pro's yesterday while on a 4 hour bike ride. During my ride I was able to place and receive telephone calls, make a Siri inquiry, and listen to music. One of my ears was slightly sore but I attribute that to the strap from my helmet rubbing against the bud.The T-12's picked up wind noise while I was riding during a telephone call. Once I stopped the wind noise disappeared. After 4 hours the buds were still running strong.I much prefer the music reproduction of these buds over my T-20's. They are discernibly better.

I purchased these on a whim during Amazon prime week and opted for the T12 Pro because of the massive battery life. Below is my experience:The earbuds last a long time. Tozo claims 9 hours. I have no problems using them throughout my entire workday. The case will supposedly charge it another 17 times or so. The case gives a digital % of the case battery life and two small graphs of the approximate battery life of each bud. Indicators tell you when it is charging and completed. Plus the case can also be used to charge your phone. The case features a USBC port for charging, and a USBA port to plug in your device to charge the device. It also can be charged wirelessly. The case is massive compared to other products and fairly heavy. This is due to the expanded battery. The bass is clear and deep. The highs, in my opinion, are too high. Compared with my studio monitor headphones that I use for mixing, I was surprised to hear things in my mixes a little too loudly like the high hats. It's not bad, just not my preference and I wish there was an app to tune the highs down just a bit closer to my taste. They are not noise cancelling, but they come with several sizes of ear buds including small and medium textured one. I use the medium textured ones and they provide a good seal in my ears and holds very well without falling out. I can barely hear anything around me when there is no music and nothing around me when the music is on. I have also used them for phone calls, and the person on the other end has stated I sound crystal clear. They are touch sensitive so you will have to learn the touch sequences for next track, previous track, answer call, reject call, and volume up and down. It's very convenient to just have to touch the right or left ear to perform the wanted function and not have to search for and push on a button that might dislodge the bud from your ear. Overall with the sound quality, battery life, and features, they are a great value for the money and I definitely recommend them.Customer service from Tozo has been amazing. After about 2 months of use, my right ear bud started doing a weird thing where it would sound normal when I first pulled it out of the case, but would gradually get quieter over about 15 minutes to the point that stereo sound was no longer meeting in the middle of my head. Very frustrating. I submitted a warranty request and Tozo gave me a factory reset procedure to do. This did not resolve my issue and they sent me a new pair which seems to be working. My only complaint is the new box it shipped in is smaller and doesn't have the earbud organizer (they are loose in a bag instead), but since you shouldn't be changing the buds that often when you get the right size it's really a non-issue. I'm assuming they shrank the retail packaging to save some costs and the earbud organizer was removed. Considering the quality and value you are getting and the low cost, it was probably a smart move to shrink the packaging.
