So i have been using my Astro A40s(2013 edition) for a good 2 years but my neighbor is selling his headphones, the Audio-Technica BPHS1 for $100(neighbor deal he says). I know Audio-Technica are well know for creating really great headphones so should i buy them to replace my A40s or should i just keep my A40s? P.S. i have a headphone amp the Fiio E10k Olympus 2
Why not see if he would let you try them. I would personally think the Audio-Technica would be the better choice, the question, is it worth $100 over what you've already got. Everyone's personal taste will vary.
