well if you are going for an i-something naming, than it must be simple and strong, therefore:
 
iNOhiss or iHissNOT
 
if you want to make it more cool (like a not joke, who doesn't like em? am i right or am i right?):
 
iHissYouNOT

 

[roskodan]

or something like
 
HissOFF

 

[roskodan]

or something like
 
Hissminator !!! seems like i was preceded

iFi iAdapter Duo (for -24dB)
 
iFi iTrimmer12

[bobrock55]

Here is my suggestion:
 
iFi iFlat

 

[C.C.S.]

Each of these names should be treated as a pair.
 
iFi Murmur (-12 dB)
iFi Murmurer (-24 dB)
 
iFi Peace (-12 dB)
iFi Quiet (-24 dB)
 
iFi Quiet Morning (-12 dB)
iFi Silent Night (-24 dB)
 
How about some opposites as well?
 
iFi Ruckus (-12 dB)
iFi Cacophony (-24 dB)
 
If anybody has already come up with any of these, I apologize.

Silent-fi series of attenuators.  Available in 12 and 24db models. Silence the hiss and turn up the fidelity.

liking this one as well.
 
 
..or SilentBridge12 / SilentBridge24
SilentHook12 / SilentHook24
 
HooverPlug/HooverPort (it sucks out the hiss)
HuvPlug/HuvPort (in case hoover is trademarked)
 
Reveal12 / Reveal24
 
Revel12 / Revel24 (which is a cute wordplay how revel means 'to enjoy oneself in lively and noisy way' while it actually works by removing the hiss but at the same time using iem enables you to enjoy oneself in noisy environment)

Adding a switch (as in the iCAN improvement) would have been a better idea, would not have been an additional cost, and would require no name.
 
Patently, ifi is a listening company. Perhaps take this on board for the next edition?

 

[limproved]

quite simply:  iLine
in the event of this entries lack of acceptance, I offer the entire dictionary, prefaced with a small "i"  of course
