PENON Volt

Volt is lmost a "money is no object" attempt at sonic success. It's simply an IEM that you can place into your ears and arrive at one with the music, as you seem to be just slightly closer to what the musical message is intended to be? At the same time there is also a distance, a way of hearing all your files, because the Volt makes all your music interesting and fun. Such an IEM personality is likable. The Volt makes friends with every cable (pretty much) you have, all the sources you have, and your whole music library.

Penon Volt is a full bodied, warm, and natural tonality earphone
Volt’s has well extended, detailed, highly resolution treble frequencies.
Mid presentation has great body and warmth, but I am not talking about a body that is suffocates the entire presentation.
The Volt has very strong, powerful bass.

Elegant, dynamic and incredibly natural sounding, Penon's Volt sets the standard for musical communication in my experience. Sound is always engaging, the even balance and superb bass are perfect for rock and pop; the rich mids and articulate treble a classical music fan's dream.

Sold my Mest and zr1. Bought these as a cheaper solution and feel they are better than the mest and zr1. Amazing , smooth tone. Cable sucks though.

Will have more to say later, but my word, this IEM is fantastic from the beginning (not even burned in yet). Sound quality is superbly detailed, yet smooth and natural, with a huge sense of staging. It's what I've always searched for in a complete IEM package...
