Only had this air fryer for a week. But the software is what makes this product really great. Initially, I was sceptical, again being a fan of big bulky over the ear headphones but I was pleasantly surprised and heres why:Great packaging with clear instructions how to setup and use the T12 earbuds. WORKS OK I have a brand new Denon receiver and two of these Denon Home 150 speakers. Fit is good. I got a 3-pack (repackaged, but still good so far, as the printed label reads correctly per the order), Bearglove scent (still as expected), 2. 99 -> $129. I have used my brands of high dollar headphones and these are just as good for a fraction of the cost! The key is also missing so I cannot use the other 2 frame locks.
