>>2065637i recently bought A30s for tax reasons, had A20s before and really didnt want to get new ones but oh well.
i have been positively surprised by the A30s.
>whole headset feels a lot higher quality>plastic pieces that hold the earpieces are a lot higher quality, same with the earpieces themselves>whole head part feels higher quality and is manufactured more "clean"on the negative side, i feel like the housing that holds the blutooth connector and the controls feels a little cheaper than the one of the A20s.
also, the cables are a little thinner, but that could be something positive (the cables on my A20 broke because i bent them where the BT housing is, might be better with thinner cables).
also, the clamping force is lower (which is good for comfort) so if i tilt my head all the way back to check something, they might move backwards on my head and i have to hold/readjust them.
i personally dont use noise cancelling a lot, dont know why i just never got into it.
but the headset itself is great, if its between used A20s or A30s, get the A30s.
