I actually purchased the CC51p's since they have a microphone which I really wanted. I didn't notice one with the A151s. Also they were about $15-20 less than the A151s. I hope I enjoy them as I listen to mostly vocals/rock music. I was really dissapointed with the sound for the S4is for Rock/vocals. If you enjoy hip-hop/electronic music they are great and have heavy bass.
