Hey guys, I have been trying to find the answer to this but have not found a clear cut answer that I am looking for. I have been back and forth on these two headphones, I bought the sennheiser momentum’s last night and they sound pretty great but the bass and quietness leaves more to be desired.

I only listen to dubstep, bass, free form bass, experimental bass music. these will be used at the gym daily. How does the bass compare on these two? I am looking for very deep bass with a strong presence. I like the M4’s but it is concerning how much I have to crank them to get acceptable bass and kick out of them. I thought I was going deaf but my girlfriend who has very sensitive ears agreed they are not very loud unless they are turned way up. Bass boost is off, I set my own custom eq and they are up to date on software.

Thanks in advance!
