I use these to listen to mp3s and wav home studio recordings. Listening to Comfortably Numb's famous pinch harmonic they really put a smile on my face.
Of course they are not flat response phones so I don't use them for studio monitoring but for sheer listening pleasure at a really good loud volume they are fantastic.
I can't say the very long lead has been a problem for me (in fact it's ideal if I need it to stretch to my HiFi or computer at the other end of my living room whilst I lounge out on the sofa) but I can imagine that if you wanted to wear them out in the street you could end up trailing an assortment of debris behind you - not ideal. Upside is that if you wore them in bed your missus might think you were getting kinky as you flicked the excess lead across her.
The head band is not at all distracting and doesn't create a sensitive pressure point on top of your noggin over prolonged use. Very comfortable on the ear too which is fully enclosed by the cushioning. Sound leakage is minimal as I can attest. No more listening to the same 4 seconds of music over and over when my son wears them and tries to get an edit 'just right'.
Much better than the ear buds that were supplied with my Sony Walkman mp3 player which were presumably designed by a committee at the EU just to annoy me - they wouldn't surprise a budgie. These Panasonics though should be kept away from all winged domestic pets in case thy cause chest cavity damage.
And they're a good price. So they've probably been discontinued now.
When I was searching for a new headphone to buy, my first port of call was to look for Technics as they are a high quality audio brand but I must say overall I am quite disappointed with these headphones. I really liked the design of the headphone with the cushion head band and the gold colour earpieces but that is not the main point of headphones and they are not bought on looks alone!. The sound quality is what makes a good headphone and I would say if you wanted listen in your headphones at home in silence, then yes this has good sound quality. However if you are like me and travel about on trains/buses plugged into an Ipod/mp3 player, then this is not for you. For instance if your on the train and its making a lot of noise your will still hear considerable amounts of background noise even when you have your player turned right up, so if you wanted to lose yourself for a few minutes with your music you can't and even when you have your player turned up to the fullest on public transport, the chances are you will be asked to turn it down as the sound from the headphones leaks pretty bad and everyone can hear what your listening to (so no Cheeky Girls okay!). But I bought mine about a year ago and they're still going so I guess that's one thing, but there lots of better headphones that are a lot cheaper than these and have better sound quality.
