I've had this adapter for about a year. I bought it for use with my JVC 'shrooms and the iPhone 4. This was meant to be a temporary fix until something of better quality came out. Sad to say, but there still isn't anything better after an e n t i r e year. I think it's safe to say that Apple or China is inhibiting the mic adapter market for iDevices. But I digress politically...
In the beginning of my experience, the adapter was a great fix for a harsh vacancy. One who loves music must surely spit when apples earbuds are mentioned. The voice quality was crisp and I didn't detect any loss of quality for music. The volume slider worked great.
Then, after one month of use, the clip decided it was through with life and promptly split at the hinge. Being the ghetto genius I am, I modded the hinge part with a paper clip and continued.
After about seven months of use the wire at the plug end began to decay, showing clear stress signs. Shortly thereafter, it separated revealing the inner guts. It took some heatshrink with electric tape to create a suitable fix. Needless to say, it became unattractive at this point.
About a month ago, I began encountering intermittent interference while on voice calls. Unfortunately it's steadily become a receiver for a gremlin minimalist band that loves to chip at my sanity with bits and bops. Talking over the sequential patterns is like trying to sing under a Chinese water torture device. It is freaking irritating. I notice that tapping/lightly slamming the volume control/control button/ microphone case seems to deliver an instant encore.
It's dead Jim.
Now after much research I find that there is still no better option. The Shure MPA-C3 is oddly vacant from the face of the planet. Griffin smart talk is described as coming apart after a month, Monster has issues with destroying pocketed iphones, and Audio-Technica has build quality issues that are almost as bad as the Griffin smart talk adapter. Just the mention of any of these aberrations makes me recoil. The saving grace is that while this brandless adapter is disposable, it's also cheap to replace. I'll be purchasing this again but this time I'll modify the heck out of it. Gorilla glue, heatshrink and some steel iBeams for good measure.
