Conclusion: Sennheiser makes earphones for the serious listener, and the CXC 700's audio performance and noise cancellation are both superbâ€”but the design wonâ€™t suit everyone.
Pros: Excellent audio performance, bass response. Quality active noise reduction. Outputs audio even when noise cancellation isnâ€™t activated, with almost no difference in audio quality. Includes â€œTalk Throughâ€� option and three different noise reduction modes.
Cons: Battery compartment is bulky/awkward. Uses triple-A battery instead of rechargeable option.
