M-Audio IE-40 earbuds

Audio equipper M-Audio is now shipping its IE-40s, a set of reference-level earbuds. Each bud is fitted with three different drivers, devoted to high-, mid- and low-end end frequencies, and reproduces a range between 20Hz and 16kHZ. Sound is further divided into separate acoustic canals, so that high- and low- end sounds do not intermix. The buds also come with four different sets of tips, providing a tight fit, and shapable ear loops to keep cables out of the way. A bundled attenuator caps the volume of loud sources, while the earbuds' main 46-inch cable can be replaced if damaged. The IE-40s are shipping today for $500 with a metal carrying case.

    $500.... five.... hundred..... dollars? USD? WTH!!??

    I don't care if these make you feel like you're having s** with your music, ear buds can't be worth $500.00.

    Reference Model?

    16kHz is the maximum frequency?! CD's are 22.05kHz, AC3 is 24kHz... Nuts I say! My own ear is still good to 18kHz... YMMV...

    if ye know not...

    ...of what ye speaketh -- just don't speak. The 22Hz-16kHz range for the headphones refers to the audio frequency... the other numbers you mention are sampling rates, not audio frequencies. By the way, the sampling rate for CDs is 44.1kHz, not 22.05. The sampling for digital audio is not directly related to audio frequency.

    mmmdoughnuts was referring to frequency (approximately).


    review nyquist-shannon sampling theory. The sample rates for digital audio are, in fact, very much related to frequency/bandwidth.
