The Beyerdynamic 770 Pro offers a superior sound quality and better noise isolation, which makes them great for immersive music listening and studio work, but they are less portable due to their larger size. The Sennheiser CX300S, although less expensive and with a smaller soundstage, provide good portability and are adequate for casual listening and travel; however, they may not deliver the depth and detail in music the Beyerdynamic headphones offer. Neither have built-in microphones, so if you need to make calls or attend meetings, you may need an additional device for that purpose. Give Feedback

"Sennheiser offers impressive bang for your buck when it comes to the CX 300S. Built like a tank and sounding surprisingly good for such a budget-minded earphone, the CX 300S out-classes many of its would-be competitors. Functional but beautiful, it’s the perfect in-ear listening solution for anyone who wants to hear everything and look good doing it."
