If you're looking for exceptional sound quality and can invest in a premium product, go for the Sennheiser IE600, as they offer the best class sound and stronger build quality, but note that they don't have a microphone for calls. Conversely, the Sennheiser CX300S, while cheaper, offer fair sound quality and good noise isolation; however, they lack a detachable cable and the overall sound is not as superior as the IE600. If you're on a budget and want a pair of earbuds for a mix of casual listening and TV without spending much, the CX300S would be a suitable choice. 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."
