Summary: The Sennheiser HD650 truly offers an incredible experience and once you listen to it for a while, there’s little doubt left as to why they are so popular. The Sennheiser HD650 are pricey, without a doubt and they’re not value-for-money, either. Here in India, they sell for a maximum retail price of Rs. 29,990. Add in the price of a decent source and amplifier, and you’re looking at good Rs. 40,000 at least, for an audiophile-class set-up.
