Sennheiser Hmec 250 Headset

摘要

A long trip in a Cirrus SR22 with a propeller turning 2,500 rpm is a tough test for any headset. A recent four-hour trip provided an oppor-tunity to test Sennheiser's new noise-cancelling HMEC250. The headset is light (10 ounces), folds flat in its slim car-rying case, and has the ability to tie directly into MP3 players and cell phones with a cord. It's also got inde- pendent volume controls for each ear, and an unusual "talk-through" button designed to allow users to hear people not tied into the aircraft radio or intercom system while keeping their headsets on. The HMEC250 proved light and comfortable on the long trip- and its active noise-cancelling feature is effective. But the HMEC250 blocked noticeably less ambient noise than either the Bose or David Clark headsets that were also in the airplane. Granted, the HMEC250 is far less expensive than the Bose model, and far lighter than the David Clark. And in a less-torturous sound environ- ment, the HMEC250 would be an excellent option. But it was quickly overwhelmed by the Cirrus' high-rpm roar.
