I bought these after owning nearly every Tozo. I had the NC2 and I gave those away as a gift. Also great and loud. The Tozo NC7 which are really useful and great all around themselves. The Tozo T12 are probably the best in sound quality of the bunch if that's what you are looking for. These will all give you great sound compared to most other brand names. That includes in higher price ranges. All these punch above their weight in price and abilities. These and the Soundpeats so far. The Soundcore also have great buds. These are the top buds if you want great performance for price. I haven't tried Lypertek but I heard great things about those. If you are looking for reviews Gamesky and El Jefe have great channels on YouTube to help you make a choice.Anyhow onto the T12's. These have about a middle of the pick battery life. Which is to great by today's standard earbuds. You'll get 5-6ish hours at max volume. They give you a good fit in your ears despite their relatively larger size. They have larger drivers in them to pump out great clear bass that hits but isn't overwhelming. The mids and treble still come through clearly very nice. Overall they have top tier sound within their price range and perhaps even at around double their price. Their soundstage is adequate. If you want a great soundstage you might want to look at the Soundpeats true engine 3. The case is very nice with a LED power level indicator on the inside. The quality is nice but a little plastic. You'll definitely want these for most tasks but if you want noise canceling I would suggest the Tozo NC7 or NC2. Overall I would definitely suggest these earbuds to anyone. Especially if you love sound quality. For a nice deep rumble in bass.
