Trotz Plastik wiegt er etwas, allein aufsetzen geht gut, erfordert aber eine gewisse Bauform des Operators. They feel like slippers that would be appropriately sized for someone with size 10 feet, and they are way too narrow. 1 sound from its 2x10w drivers and a 20w subwoofer with bass port for a total of 40w. poooor construction! the mic is good and the battery lasts a long time and they connect pretty easily. The wire is also thicker and stiffer which makes it uncomfortable as they are all kinked up and even after trying to loosen them up it just doesnt work. I’m sending an email to customer service but I’m in the middle of no where on the AT with limited service and now have to deal with this?! Continuing to tighten the knob simply pulls the nut out of the knob. Love the over-the-ear headphones over on-ear, so much more comfortable. I will update my review if anything changes.
