I really wanted to give top rating to Newer Technology’s Headphone Jack Adapter. After all, it does the intended job very well. It’s also priced $2 less than Griffin Technology’s adapter and $3 less than Belkin’s.

Unfortunately, the aforementioned three-ring tip problem is also present in this adapter. If not for this issue, I would use my Bose QC2 headphones and this adapter to enjoy music on my iPhone. There’s no reason I shouldn’t be able to listen to a caller through my Bose cans while simply holding the iPhone up to my mouth so the caller can hear me. The Mic Extender Cable (see above) with its in-line microphone solves the problem.

In the likely few cases when someone owns a preferred set of headphones that does have an in-line microphone, Newer Technology’s adapter is the best choice, since it would carry the microphone’s signal through the third ring. Those individuals might feel this product deserves an Excellent rating.
