The Bang & Olufsen Beoplay EQ earbuds, while more expensive, offer wireless convenience, active noise cancelling, and are sweatproof, making them suitable for exercise and travel. They have aptX Adaptive support, ensuring better sound quality over Bluetooth, and a better build quality. The Sennheiser CX300S are less expensive with a wired connection, which can be more reliable and offer no latency issues, making them good for TV and gaming. However, they lack a microphone, active noise cancellation, and wireless features. Choose the Beoplay EQ for a premium, versatile wireless experience or the CX300S for a reliable wired connection at a lower cost. Give Feedback

"Bang & Olufsen’s audio products prioritize style and function just as much as sound quality. The company’s latest Beoplay EQ noise-cancelling true wireless earphones combine strong, accurate-leaning audio with solid noise cancellation in an exceedingly classy design."

"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."
