To be honest I wasn’t expecting much out of these earbuds but I may have been wrong. Initial fit in my ear was excellent with the preinstalled tips although they send quite a few in the box. My other set of earbuds are the Tozo T6 and I absolutely love them but the Taotronics actually fit a bit nicer. I chose the Tozo T6 partially due to the case size and shape but was pleasantly surprised by the size of this case. One thing I do appreciate about the T6 case is the 4 dot battery indicator light that lets me know when the case needs to be charged. That’s something I don’t see on the Taotronics.I was impressed with initial sound quality and will chime back in when I get some more seat time with these. I work a job at night where I listen to music or audiobooks for 2-3 hours per night so having something that fits nicely and sounds good is a priority.I’m unsure what battery life looks like but wouldn’t be surprised if they outlast my night job.Update 1/8/21: After using these for the week at my night job I've found things I both like and dislike.I was right and the battery life, at least while still this new, is excellent. They outlast the T6's after a combination of listening to music and talking on the phone for the last 5 nights. They still fit and sound great. Being able to summon Siri on command is nice since I still have not remembered the right combination of button pushes/presses to do so on the T6's.That being said the controls on these Taotronics can be cumbersome. I wish there was a single press to pause/play music instead of the double tap as I often don't get the timing right. If someone stops to talk to me while I'm working I end up fiddling with these to get them to stop playing so I can hear what's being said. I only wear one earbud at work because I prefer to be able to hear ambient noises for safety purposes. The good news is that these fit so well that if I were wearing both I doubt I would be able to hear anything else.I dislike how these pair with my phone. The initial pairing is great and super easy. If I pull both buds from the case and then return one it uses the same "Taotronics Soundliberty97" pairing. If I pull just the right bud out it made me pair just that one bud under "Taotronics Soundliberty 97 R" and I'm assuming the same would be true for the left bud but haven't tried just the left yet. While not a deal breaker it is slightly annoying to have "Taotronics Soundliberty..." listed thrice in my bluetooth list.My last complaint is about how these work with my bluetooth radio in my truck. It may simply be that my Pioneer bluetooth radio and these Toatronics don't play nice together as I haven't tried these with any of my other bluetooth devices/radios. I use my truck for work at night and am in and out of it every 15-30 minutes. Every time I crank my truck my phone auto-connects to my Pioneer radio. If I'm listening to music or talking on the phone I've noticed that almost every single time the Taotronics earbuds flip out and automatically disconnect and then attempt a reconnection which sometimes completely fails. Annoying if you're listening to music, aggravating if you're on a phone call. My T6's used to make this transition seamlessly but have started having the same problem recently but with a much better and quicker reconnection. That being said this may just be something that happens when trying the hand-off between that many bluetooth devices.
