I just played a music sample from the "Boardwalk Hall Auditorium Organ" that has a real 64-foot pipe, which plays at 8 hz. That's too low to hear the fundamental tone in the tonal sense, but it's not too low to feel the weight of that note on a headphone with good bass extension. So how did my headphones do? On a scale of 1 (weakest or most breakup) to 10 (best weight and lack of breakup distortion): B&O H6 - 10. B&W P7 - 7. Thinksound ON1 - 5. Shure 1540 - 5. v-moda M80 - 4. Beyer T51p - 3. Harman Soho - 3. If anyone doubts that 8 hz is a working fundamental on a headphone, just try the H6. Here's a more musically relevant pipe - especially for headphones, a 32-footer that produces a 16 hz tone. Note the boominess late in the track. This boominess was a point of discussion in the organ stops pages - the need to prevent such things in design or practice. www.organstops.org/_sounds/KelloggAuditorium/Ped_Resultant_arp.mp3And the 8 hz tone from the 64-foot pipe: www.die-orgelseite.de/audio/atlanticcity_64ft.mp3

Hi, An interesting one that. I tried it with my Sen HD650, AKG 701 and Denon Ah D 2000. I couldn't try the 16 Hz as the link seems broken but I got good results with the 8 Hz. What it showed me more than anything else is just how transient our auditory memory is. By the time I had swapped over headphones it was difficult to give any meaningful rating and this wasn't helped by the differing impedance of the cans. In any test of audio it is imperative to get the volume the same as otherwise there is a strong bias towards the louder and the odd thing is that you may not even be aware that one is louder, the difference only need be that slight. It really needs to be correctly calibrated with a meter.

I tried the Kellogg link just now and it still works - it plays the MP3 directly.

Bloody Hell ! I just tried the Kellogg link again and get the message that the domain cannot be resolved. Perhaps it is my browser - Maxthon.

I tried the two samples on a few of my phones. My Sony XB700 didn't fare too well (could hear but not feel 'da bass man), the HD-25's worse (could barely hear any bass), my DT700s are broken alas, and my Q701s are at home (and wouldn't do well I'm sure). By far the best were my (shudder) - Wesc RZA Chambers. A 'rappers' phone that was going for mega cheap at HMV so had to get them. The bass seemed accurate, and not remotely boomy, could feel my ear drums wobble.

The interesting and confusing thing is, even though you can't hear the 16 hz fundamental (but can feel it), you can "hear" the 16 beats per second through a 32 hz or higher harmonic. I would love to hear the tech explanation for that.
