First of all is the equipment for the price is OK, though no bag, but still S and L supplied adapter; therefore highly adaptable to your own ear canal, no wobbling or slipping, class !!
The first sound test at Philips GoGear with titles like Feuer Frei, Hells Bells, Save Tonight finished hoped, powerful bass. Ups and downs are also clearly resolved, it followed the classical music test.
Here, the headphones met with extreme highs and lows in the soundtracks of The Lord of the Rings, Jurassic Park and Braveheart partly to its limits, it lacked the ultimate clarity; also could be heard in quiet passages a soft grinding or scraping, but this does not really stand noticeably uncomfortable. The supplied headphones beats it at Philips but noticeably, the dynamic range is significantly better.
Therefore, I forgive the maximum number of points, because given the price the delivered power is fully satisfactory. For me personally, these headphones is the optimum, as I go hear more bass intense rock and metal. However, those who want to experience classic pieces in full quality, should resort to models from Bose and Beyerdynamic, which costs but also equal to 4-5 fold.
