Conclusion: For $260, Sennheiser's PXC 250-II is a good pair of noise-canceling headphones, but if you can afford them, more expensive pairs, like Bose's QuietComfort 3, deliver much better performance.
Pros: Effective noise cancellation. Can be used in passive, non-noise canceling mode. Solid audio performance at moderate volume levels.
Cons: Distorts at higher volume levels on bass-heavy tracks. Large noise cancellation/battery compartment on cable. Runs on a standard (not rechargeable) AA battery.
Summary: D o you prefer on-ear headphones or in-ear buds? Sennheiser , the German uber-brand, is well-known for its pro and consumer audio products, as well as for its breathtaking (and expensive) Neumann microphones. Now, the company has updated its well-loved PXC 250 travel headphones with a hot new look, better ergonomics and a slight performance bump.
Excerpt: The Sennheiser PXC 250-IIs win a prize for the their portability. You’ll be forgiven for handling them with care, but the steel headband is strong, so there’s no worry there. On the downside, though, they’re just not that fun to listen to. While there’s decent detail and separation, the dynamics are slightly biased towards the vocals.
Pros: Highly portable, compact design, good detail
