Hi guys, i've got two headphones for my consideration- which is

1. AUDIO TECHNICA ATH-M50RD (RM600++)
2. Sennheiser Momentum (RM1100++)

Sound wise, which one is better? I might be using the earphones at home, commuting or in the library. I'm still wondering wether I should fork out another RM500 top up for the sennheiser.

Thanks guys!
