My V6s are almost a year old. They're in excellent condition, and will come with the screw-on adapter and pleather carry pouch. If you buy them, you can also have my Audio Technica HA-02 headphone amp, which looks cool but doesn't do much for sound, for free (it's available from Audiocubes for about $60.) The price is $50, which includes USPS priority or UPS ground shipping, at my option. I have some favorable feedback here, and will cross-ship with anyone who also has some.
Please email and PM me for best response. I have no 'net connection at home right now, so can only reply during business hours.
