Im not sure if I want to get the astro a50 or the astro a20. Which has better sound? People say the astro a10 has better sound than astro a50 so im thinking the astro a50 has better sound than the a20s?. Im pretty sure the astro a50s with the leather ear cups are more comfortable than the a20s? But then i hear people have problems with the a50s which worries me. I hope they fixed them all. I care most about sound and comfort. Whats your opinion? People say the a20 headband is uncomfortable.
