Alright so I have used my Samsung Gear IconX 2018 for about 5 days, and these are my thoughts so far.
1. Connectivity
The bluetooth connection is pretty stable even in crowded places or commuting, but there can be cut offs in 1 side, but quite rarely and usually it is like a split second.
For the issue that I was having (opening the charging case, phone bluetooth settings showed that earbuds connected, but app doesnt show so), I realise there's a fixed way that Samsung wants us to use the earbuds or maybe its just my phone. I have to turn on my phone's bluetooth, wait for the scanning pop up and then open the charging case. Once I see its connected for audio/media/call, then i close the pop up, enter the Samsung Gear App, then it shows connected there.
2. Comfort
The earbuds will stay in your ears quite firmly with the right fit of wingtips and eartips. But I find even the smallest wingtip presses against my ear too hard, and ear fatigue is real here. Once again, maybe its just my ear shape or I'm wearing them wrongly. The pressure of the tips on my ear is much more bearable when I'm walking, or just sitting upright, but when lying down it feels kinda uncomfortable.
3. Touch Sensor
There's a touch sensor on each earbud to tell if they are in your ears or not, and I totally dislike this feature. Sometimes even if the earbud is in my ear, the sensor doesnt tell so. So at times when I want to only use 1 earbud, I remove the side that is actually "touching" my ear, with the other side not detecting its in my ear, my media will pause, and you would need to readjust for the earbud to register that its in your ear.
I won't comment on the audio part, as I'm no audio expert and I was not looking for audio quality when I bought it, but more of looking for something for me to use on the go, on the move.
