If noise cancellation and comfort are priorities for you during activities like air travel and TV watching, the Bose Quiet Comfort Ultra Headphones would be more suitable, despite the higher cost. They offer excellent noise isolation, superior battery life, wireless connectivity with low latency, and active noise cancelling, which the Sennheiser CX300S lacks. However, should you prefer a more budget-friendly option with a simple plug-and-play setup for casual music listening and you don't mind the absence of wireless functionality and noise cancelling, the Sennheiser CX300S would suffice. Keep in mind, though, the Bose offers extra features like app equalization, foldability, and optimized audio controls for both Android and Apple devices. Give Feedback

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.
