Compact headset with good bass reproduction. Comfortable to wear. Cable length is sufficient. For the money, I do not hardly comparable found. (3 other tested) I just talked to the dealer I trust and whose testimony is: Such headphones have indeed often great values 10-22000 Hz, etc. but sound rather weak.
The Panasonic RP-HT010E-A headphones I'm really happy. Only a material fatigue in the bracket (adjusting the strap size) I have now fixed by glue.
I wish that the headphones would be a bit louder. My MP3 player I have to go put on high volume.
