My mum got these free when she opened a bank account in Hong Kong, but these can be bought for around £5 here in the UK.
Stylishly packaged in a plastic tube, the earphones are encapsulated in their home, with minimal packaging. Apart from the transparent clear exterior, a vacuum formed tray holds the earphones in place, whilst a clearly printed cardboard sleeve relays all the vital technical details, as well as a few useful diagrams of the 'easy clip mechanism', but more on that later.
Firstly, the earphones themselves are made of a 'gummi' plastic/polymer material which feels good to the touch and is flexible, but thankfully the wires aren't made of the same material. Having previously used the JVC gummi earphones where the whole thing was the same gummi material, the wires stuck together and attracted a lot of dirt and dust, and from the white colour it started out with, became grey. Luckily, that won't happen to these Panasonic ones.
Fitting into your ear nicely, the sound quality is good/above average. It doesn't provide the most immersive audio experience, but is acceptable for the price range. Using these with iPods or other high end audio systems will not showcase their audio prowess.
The selling point to these earphones is clearly the design. The separator between the two earphones are pretty far apart, so if you were to share with someone or you're listening with one earphone each, you can be sitting across a small desk or comfortably on either sides of a car.
Now onto the 'easy clip mechanism'. On the top of the earphone there is a 'C' shaped clip or gorge embedded into the top which allows both earphones to be clipped together, earphones to be clipped to the wire or apparently to your t shirt/clothes. Personally, I think it's a nice touch and concept but the result is absolutely useless. I have not needed to do this at all and it does not hold when I try to clip it to my clothes.
Overall, the design of the Panasonic RP-HV21E-A earphones are exceptional in concept and appearance but the overall sound quality is lacking. An improvement in this area will surely cost more, but those extra pounds will be worthwhile for an all round solid piece of audio candy.
