Hmm, that's interesting. Most of the reviews say it has pretty decent bass. I'm not a basshead but do enjoy some extra punch at the bottom end

From what I understand BA driver earphones are often times sealed while dynamic drivers have holes in them since they need air

I've already done tons of reading on a number of different earphones and those are what I narrowed it down to. Also the headphonelist has the A151p and UE600 rated the same for isolation but my experience the UE600 had much better isolation even with just a single flange silicone tip. Right now...

Howdy. I'm new around here so let me give some background. I used to be a sound engineer. During that time I found that I really enjoyed a V-shaped sound for the most part. And high female vocals. I listen to a weird range of music mostly consisting of hard rock, alternative rock, metal, folk...

I liked the a151p but you are right about the bass not being very powerful. They are more of a balanced earphone and I liked the clarity. I think mine are the 1st generation but I'm not sure.
