2.0 out of 5 stars
Works as advertised, marks deducted for overall shoddy build quality, 8 May 2012
Just got this off Amazon as a stop-gap solution to use regular in-ear monitors on an iPhone.
The product itself works well with most standard 3.5mm stereo-jack headphones that are terminated for the iPod/iPhone (read: small/narrow jacks) and the internal cabling used does not degrade the audio quality as much as most of the standard TRRS to TRS converters you'll find out there (or not audibly to most ears, at least!). So that means, other practicalities aside, it should scale well during use with other sensitive, high-quality in-ears that do not really need additional amplification through line-out docks, which does not allow the user to take calls on an iPhone anyway.
Mic audio quality is not too shabby too. Voice calls and memos make their way through crystal clear compared to the iPhone's standard white in-line mic.
While I have not tried this myself, I believe this product should work with most Android devices as a standard mic/headphone/controller extension too (at least from experience with other similar products).
While the packaging itself includes some niceties such as detachable cable clips/ties to hold the cable of your headphones to the Belkin mic, I find that, in reality, these are absolutely useless at the job. Instead, I would highly recommend using electricians' black tape, esp if you're intending to get these for use in rigorous activities such as running or biking. The trade-off is that it results in a very ghetto look, though. (Or maybe one can try jazzing it up with something else more colourful, like 1.5 mm braided cable sleeves and a bit of heatshrink)
While the gold-plated jacks and choice of rubberised "anti-snag" cables are pluses in the overall build, the COMPLETE lack of *any* form of tactile feedback in the actual control unit (i.e. the buttons) are a MAJOR detractor for anyone who has ever used a competing product (like the Griffin mic). Suffice to say, the lack of feel in the control buttons also translates to a generally poor performance in the responsiveness of the controls. Both of these add up to be a major bugbear especially for people intending to use this as a mobile hands-free kit while on the commute (with it being a major distraction and actually spending more time getting the desired result). So, in the interests of road safety, I strongly do not recommend this to cyclists, drivers and motorcyclists.
So, we start with full marks there on fulfilling its function (3 stars), having decent internal cabling (1 star) and generally good audio quality (1 star). However, I deduct a star for user ergonomics (cable should have been about another 10 cm longer and the 3.5 socket made wider to accept headphones with bigger diameter plugs) and further deduct another star for a complete failure in the build quality of the controller end (in turn, leading to a further deduction of one more star for safety/narrowing the user base to joggers and strictly for use when not operating a vehicle).
