If you prioritize wireless convenience and frequently take calls or attend meetings, the Sennheiser HD 250BT headphones are a more suitable choice as they have built-in controls, better mic quality, and wireless features. However, if portability and a higher noise isolation quality are important to you, and you're looking for a wired option, consider the Sennheiser CX300S earbuds. Bear in mind the CX300S may be more expensive, and neither of these options have active noise cancelling. The HD 250BT also offers longer battery life and low latency, which is great for gaming and watching videos. Give Feedback

Carroll Moore | April 2019
"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."

These headphones may not be among the most comfortable, but they deliver adequate sound – without overdriving or distortion."
