My pad-rolling report on the Hemp:
Sennheiser 414 ‘Yellow’ pads (with Quarter mod)
The Sennheiser pads are a clear comfort upgrade over the Stock F-Cush pads and are also closest to them in terms of overall signature. While they also have an exposed driver thanks to the ‘Quarter mod’, the thicker pads move the driver further away from the ear, and as a result, offer a slightly drier tone with less immediacy. The 414 pads also cause upper mids to dip slightly, along with a lowering in mid-bass impact.
S-Cush ‘flat pads’
The stock pads on the entry-level ‘Prestige’ Series Grado model give a noticeable improvement in smoothness on The Hemp Headphone, at the expense of treble clarity and overall energy. While they’re far more tolerable in terms of comfort, they do reduce the fun-factor of The Hemp Headphone.
L-Cush ‘bowl pads’
The addition of the OEM Grado ‘bowl’ pads makes for an interesting change. The Hemp Headphone becomes more incisive, with a snappier treble response and a leaner, more spacious overall feel. While this does tame their signature warmth, it might be worth keeping a pair of these pads on-hand to complement the stock pads and change things up from time to time.
G-Cush
These sound awful on The Hemp Headphone. They leave a veritable canyon in the mid-range, voices become nasally and distant, and treble is etched and sharp. Avoid.
Beautiful-audio leather/merino hybrid pads
These terrific-looking aftermarket pads from Beautiful Audio fall somewhere between the stock F-Cush pads and the L-Cush in terms of signature, and also happen to be the most comfortable pick of the bunch. They add a lower treble boost, plus add a bit of additional width and air The Hemp Headphones sound stage. Their overall mid-bass impact is reduced, but it does become tightened-up in the process. While these look great and sound pretty decent too on The Hemp Headphone, they are an expensive aftermarket proposition and do tend to remove much that makes them unique-sounding in the process.
