Am I right in thinking its best to get some with a built in amp if using them with a portable device?
I've tried a few pairs such as Sennheiser's but I found them a bit quiet and not very bassy. I don't want to get any beats headphones. I was reading about the Sony Mdr-1r but haven't been able to find any yet to try. I read they aren't so bassy though.
I was thinking of paying upto about £160.
