    low bitrate WMA and headphones

    When talking about sample rates it gets more complicated than 44.1k being ok for anything below 22.05kHz. The difficulty arises in the recording stage before the A/D conversion. Frequencies above half x the sampling frequency have to be completely filtered out with analogue filters, otherwise...

    Beyerdynamic DT 880 vs Sennheiser HD 650

    I got my Beyer DT880 last week, and from all the descriptions I've read it would seem that equalizers haven't been invented yet. By producing an EQ curve that is an upside down version of the Headroom measurements, I've greatly improved their sound. It has eliminated the treble peak that causes...

    First impressions of Sennheiser's "PXC 250" NC cans

    I'm pleased,... but also a bit disappointed I received a new pair of Sennheiser PXC 250 noise cancelling headphones just the other day, and while I'm mostly happy with them, I'm hugely disappointed with one aspect, and that is the noise cancellation at low frequencies. It doesn't compare well...

    Headphones with fast spectral decay and without midrange resonances?

    I was actually looking at those "in-ear" electrostatics earlier. Do they block the ears like the Etys and Shures? My ears are pretty sensitive to DC pressure changes, so I wouldn't be able to live with that sort of thing unfortunately.

    Headphones with fast spectral decay and without midrange resonances?

    Thanks people . Where would it be possible to see measurements of far-field sounds as heard by a dummyhead, especially of sounds above 1kHz? This could probably be done with a high quality tweeter EQ'd with DSP, and played at a sufficient distance from the dummyhead to ensure that resonances are...

    Headphones with fast spectral decay and without midrange resonances?

    Quote: Originally Posted by Eagle_Driver Headphone design is a compromise. Very small drivers (10mm) have never worked well in large-cup headphones - in such a large enclosure, tiny drivers provide no bass at all whatsoever (regardless of the material), nor can they provide any response...
