I've been heeing and hawing over doing this review for a few weeks, but now have spent enough time with the T12s to give them an honest review.Going to break this down to 'Good' and 'Bad' sections rather than my normal large paragraph format. So, here we go -->GOOD:- The sound quality. I'm not an audiophile by any stretch, but I think these sound great especially for the price.- The charging case. Quality feels outstanding and the little display that indicates charge status (and % of the charge case) is fantastic. Not only does the case support wireless charging, but each earbud has a magnet in it that attracts it to its bay in the case. Super nice touch there.- The battery life. Super impressive given the size of the earbuds.- The claim of being waterproof seems to hold up. The first day I took them outside to use while washing my car, it took all of nine seconds for one to fall into my wash bucket. It survived without issue and continues to work to this day.- Packaging. For the price, the overall packaging of the T12s is pretty nice.BAD:- Fitment. The T12s utterly failed the yardwork and car wash tests. I went through each included ear attachment piece and they still fall out relatively easy. When sitting relatively still, they seem to stay in OK, though.- Sensitivity of tap controls. It's just too sensitive -- like, when one of the earbuds is about to fall out and you go to put it back in, it pauses or skips tracks. I've also noticed the volume going up or down several times without any input from me.. have seen other people here report this.FINAL THOUGHTS :I really want to like these. So much so that I'm going to keep them and keep at trying to make them fit/stay in better. I feel like I can deal with the overly-sensitive touch controls if they stayed in my ears, especially given the price.I wish I could give these 3.5 stars. With that being said, the value of the Tozo T12s is unquestionably high, and the charge case is fantastic, so 4 stars it is. Will absolutely come back and update this review if I can get them to stay in my ears while doing work outside!
