i had the AKG k550, but they didn't have "any bass". so I took them back and got the sennheiser HD650. they fit so tight on my head, so I took them back as well. now, I have the AKG k545 and I am so happy with these headphones. they have enough bass. there was a little bump in the upper mid range at first, but that has since settled down. I am wondering about how the k545's work, however. I'm wondering how the sound gets from the left ear to the right ear (with no visible wires). could there possibly be a transmitter in the left ear and a receiver in the right ear? any comments welcome. thanks, john.
