Given that I found them for 8990, and bought them with discounts for a previous purchase for only 7500, this is the best you can choose from full-size headphones! I would take for 12022, they are worth it! Unfortunately, I use it with iPod nano, so I can't reveal all the possibilities of sound. But I can say for sure that in comparison with Momentum, which by the way cost 7990, these headphones, even with an iPod, give a more pleasant listening experience. I believe that in conjunction with a more worthy player, the sound will be even better and will give a more objective assessment of the capabilities of the M50X. Conclusion: Definitely worth buying. Satisfied!
