Good Clear Ear Buds
Nice Comfortable Ear Buds with clear sound quality and doesn't fall of your ears. As Open Earbuds, they work well if the surrounding environment isn't loud (70+ db minimum for you to turn it to near max volume to hear better) and you can hear both audio and external sounds without either interferring. I haven't played around with the touch settings too much but adjusting volume might be tricky (left to lower and right for higher). Microphone quality is decent as long as there is no winds in the background. Rotating case feels like a fidget toy and weighs a good bit. Satisfied with it so far.

They won’t last past a few months!
Bought them in December, 100% only used them inside the office with the volume pretty low. By early April the speakers speakers stopped working. You can tell they were on and connected but their volume wouldn’t match. One was loud the other very low. Don’t expect to use these for longer than a few months if you buy them! Very low quality and the case is terrible, it offers no protection forcing me to buy a case for the case. Madness lol.

Heavy af
Great sound, quality made, wayyyyy too heavy and hurt my ears after short time wearing. So much so that after 45 min of wear, it took 2 days to stop being sore/tender. Again, this is an excellent option for people with ears that can lift prison weights

All around perfect fit
I use these for Zoom calls, my iPhone, Laptop and TV (when my wife wants quiet), no ear fatigue and sound clarity is great.

Too much background noise
I thought these were working well until the people I was talking to stated how much interference they could hear. Everything sounded far away and garbled to them.

Nice alternative ear buds for the price
These Monster headphones deliver impressive sound quality with their 14.2mm drivers. The open-ear design is fantastic for situational awareness, and the secure fit is comfortable for all-day wear. Bluetooth 5.4 provides a stable connection, and the battery life is excellent. The rotating case is unique and fun, though a bit bulky.

Great sound
The sound is excellent, as I expected from Monster. The mic is good but when used, I sound a bit far away, but still has clarity.As for comfort, it's good but I wear glasses and the fit is not great. They have become my go to for my MS Teams' meetings.Good value and excellent battery life.
