When I updated my iPhone 3G S case from a simple rubber case to a Speck Products CandyShell Case for iPhone 3G, 3G S (Black/Gray), my 3rd party headphones would no longer fit tightly into the iPhone jack as the opening in the Speck case was too small for the plug. This adapter solves that problem perfectly due to the very narrow plug on the male end.
The connections on both ends of the adapter are very snug.
Thus far I have noticed no negative affects from using this adapter. I have experienced no sound drop-outs or distortions of any kind. My only issue is that when I remove the adapter from iPhone, I do get a rather loud pop through my speakers, even if nothing is playing at the time. But, that is a minor issue for sure.
Given the VERY inexpensive price for this adapter (a similar adapter at RadioShack cost me $9.99) it is cheap enough to replace a couple times a year without too much complaint... And, despite its low cost, it doesn't feel cheap at all. Highly recommended. Headphone Adapter for Apple iPhone Recessed Jack, 3.5mm Male Female Extension Plug - White
The product description is inaccurate. I selected it because the original iPhone has a recessed headphone jack, unlike later models. This causes a problem for third-party headphone plugs, which are too wide for the narrow recessed area which leads to the jack.
Because this item DOES NOT FIT in this narrow opening, I was unable to use it. My time and money were wasted on this product. I cannot use my third-party headphones with my iPhone. I must use the poor-quality Apple earbuds, or buy another adapter which actually works.
If it had been accurately described, I would not have purchased it!
I order three of these at the same time and all three are worthless. Two of the connectors sounded like crap with volume reduced at least 50% and not in stereo. The third did not work at ALL!
So, three up and three down. Avoid this product and or seller.
If you're looking for a headphone adapter only, this is fine, although it appears a little flimsy. However, although it implies in the description that it carries the microphone signal, this is NOT the case. The precise wording is: "Allows the adapter to be used with stereo headphones that also have integrated microphone functionality". So, yes, you can use it with such headphones, but not for the "microphone functionality". See more details in a previous review (Won't fit 1st gen iPhone and Can't make calls, July 22, 2010 By F Shopper).
This adapter works great on my iPhone4 with Apple bumper case. The male section has three rings and a tip for a total of four conductors and that's what you want for an iPhone4. The white color matches Apple's while cord on their supplied headphones. The male sleeve is small enough to fit in the Apple bumper case. I've just had these for a few days so I can't yet comment on the durability.
Description says it carries the microphone signal. Description also says it has a Stereo Socket. These are contradictory statements: Stereo + mic requires a 4 pole plug and Stereo only uses a 3 pole plug. Can't both be true.
I bought the black version, Headphone Adapter for Apple iPhone Recessed Jack, 3.5mm Male Female Extension Plug - Black trusting in the description that it would carry the mic signal into my 1st gen iPhone. Turns out the Stereo Socket description must be correct because it will not carry the mic signal into the iPhone.
And to boot, the plug molding is TOO WIDE, DOES NOT FIT into the recessed jack of my 1st gen iPhone. Only after paring it down with a knife, did I find out that it didn't even carry the mic signal.
MediaMart sells another adaptor, Headphone Adapter for Apple iPhone Recessed Jack, 3.5mm Male Female Extension Plug - Black with identical item name. It's tech description is almost identical except it says that it has 4 pole connectors at both ends. Assuming that description is correct, I would have bought that product if the two products had been correctly described.
