Owner of a Klipsch Image One, I was attracted by the low price of this article. I use it in combination with an iPhone 3Gs. I have not yet received the cable FiiO L3 already ordered. The aesthetic impression is good. However, the glossy black plastic "cheap" brand enough: fingerprints are very visible. The size of the object is greater than what I expected: it's bigger than an iPod Shuffle for example. The portable listening can be difficult despite the clear plastic ties that complement the presentation but we are not obliged to use. At power color LEDs produce a pleasant effect. The battery is charged when the parcel is debalé and we are told 10 hours. The cable for recharging the battery is provided (from a USB port). Also provided 2 audio cables of different lengths. They are to be connected in jack 3.5. I logically ordered another connector: L3 which starts from "30-pin" to the input of the amplifier. The output remains 3.5 jack course. Once the connection is made has volume controls on the amp, 3-mode equalizer and a hold position. The maximum volume rises considerably. The headset delivers a warmer sound distortion but leaves no illusions about the insufficient amplification of an original iPod. Worse, the sound rose to its maximum is so strong and so low that I must present frankly qualify the product potentially dangerous. The sound becomes "insane": one must necessarily observe a reasonable volume to not end up deaf and / or with a migraine. The headset delivers a clean sound, however, to a certain extent. The headphone remote control does not work once connected E6. After connecting product clutter makes it more portable than laptop because nothing beats a good headphone amp without such a practical point of view.
