Bests & Worsts Reviews from Amazon

UPDATE: TOZO is sending a new set to see if the right channel was the problem. They are trying very hard to please me, including offering a full refund (return unnecessary). I opted to try the new buds because I really like the sound and how well they stay in my ears. ---------------- TOZO sent me a new left channel earbud when I told them about the problem with it dropping out. Only took a week to get the new one! After resetting the earbuds according to their directions, the newly reset left channel continued to drop out like the old one. It's possible that the problem is with the right bud, but they only sent the left. Most likely it's a bad design that only works for some people in some environments. After some research it would appear that it is rare for bluetooth headphones to work right all the time, so Tozo is not unique in this aspect. I've read that Bose makes some that work, but the reviews on Amazon belie that. Since I own a set of Apple AirPods, and they work great, I know it's possible to design something that functions properly, electronically (AirPods slip out and are not water resistant). There are several reasons why wireless earbuds might drop out on the left channel, but all revolve around the signal. Bluetooth transmits the left and right channels to the right bud (master), and then the right bud sends the left channel to the left bud (slave) via another bluetooth channel. Since most heads tend to attenuate the signal, very little signal gets through skin, skull, brain, and blood. It's better to get the antennas outside the ear so the signal can go around the head, so to speak. I suspect Apple figured that out and put the antenna in that little stem that hangs out of the ear. It's sad that these TOZO earbuds don't work worth a darn since they sound rather good for bluetooth audio from an MP3 file, and wireless bluetooth is so convenient when out running, cycling, etc. So now it's back to the Apple AirPods that slip out of my ears. Ugh!
