FiiO L3 :: line-out cable for iPod / iPhone / iPad. It is said that silence is golden! Maybe, but now the sound of "The Apple" also thanks to the connections of the L3 gold plated, which coupled eg "Headphone Amplifier" of the same brand, reproduced perfectly (even improves) all genres of music (from classical to R & B, soul, funk, electro, ...). With Koss PortaPro (an accessible price thanks to Amazon) for about 70 euros overall (+ headphone connector Amp FiiO L3), all "Monster Beat" Dre pale in ... (190 to 500 euros anyway, + fees ENT expected soon ...) Fashion victims OK, but not at the expense of true quality !!! And gaffe eardrums with closed helmets (MB-type, ...). The Koss is adjustable it (semi-open or closed) for more than 25 years !!! Thank you to our ears. FiiO thank you to decline this quality range (except the L1 that is not worth much) avoiding us "bad apples" ...
