2 Pack Headset Audio Jack Extender, 3.5mm Gold Plated Headphone Audio Jack Extension Adapter for Battery Charger Case, Power Case, Juice Pack for Smartphones, Tablets, Credit Card Readers (3in)

My intended use was to allow me to plug my headphones into a phone with a case that prevents me from plugging in the headphones directly. Within an hour the point where the cable attaches to the male end of the cable had split apart and exposed the wire (just from being in my pocket). I found it odd that they only chose to reinforce the female portion of the cable, which seems like it would take less wear. While I'm sure it would function fine in a completely stationary environment, I was expecting this would be a common application for this extender. Would not recommend for use with a phone case.

I bought this for my boyfriend who just bought the Samsung Galaxy S10. His car isn’t equipped with Bluetooth, so in order for him to listen to music from his phone he has to use an auxiliary cord. Unfortunately the standard auxiliary doesn’t fit into the Galaxy S10 with a phone case on. He was so upset until I did some research and found this little baby! It works perfect! For anyone out there with the same issue, don’t hesitate to buy these. Such a great price, fast shipping and you get 2!!

They work flawlessly with my iPhone 6s in the Apple battery case. No issues with audio quality or connectivity, and thus far (after only a month or so of use, granted) there's been no indications of undue wear or degradation. They are fairly thin and are of course inexpensive, so time will tell how they hold up to frequent, actual use.I can't give a five-star rating because at the end of the day I still have this extra dongle to worry about, and it juts out a little awkwardly from the battery case… though in fairness one could pin the blame for all of this squarely on Apple, as much as anyone else.

Allows me to plug my headphones into my phone without taking it out of the case. Oddly enough my phone registers it as a headset? My only complaint is the volume and sound quality went down when my headphones were plugged into this instead of directly into the phone.EDIT JULY 2018: the first one is starting to go, thought it might be the headpones but when I plug them directly into the jack everything is fine. Kind of bummed since I'm not particularly rough with them, I consider what I put it through to be normal use and it's only been three months and already it's dying. Taking off a star.

I use Etymotic Research ER4 in-ear headphones to listen to music on my iPhone while on my walks. They worked fine with my iPhone 3GS and iFrogz case. I finally got a new iPhone (the 6S) with a Moshi case. However, that case doesn't accommodate the ER4's standard 90-degree angle headphone jack. Moshi claimed that it should work and offered to exchange for a case with features I don't want or need, plus I like the look of the case I have. Etymotic Research suggested several extenders and I chose this one, both to have a spare and because it was the least costly option. It works! If only all phone case manufacturers would make products that actually accommodate standard jacks, I wouldn't have to spend even more money on a workaround.

Addendum; bought two more of these, a four work fine.My profession requires on-site credit card payment, yet my new cell case does not accept the plug-in of a SwipeNet reader. I went through several "card reader extentsions" yet none of them would recognize the reader - this one does.I do recommend, however, that this extension is treated delicately, as the cable is very small, yet inside that cable is 4 shielded wires, making each wire extremely small and prone to breaking.Thanks,Hubby

I bought these because a regular headphone cord doesn't fit in my Samsung Note with the case on. Theselittle extensions work perfectly. I like that they are pliable and seem less likely to damage the jack if bumped. They arrived very fast.

Can't express how useful these are. I bought a pair of these extenders because I noticed that the metal headphone connection on my favorite pair of earbuds was starting to bed a little. I kept my earbuds hooked into one of these for 2 months and I didn't see any more wear and tear on the headphones themselves. That being said, the extension did start to wear after a while, but luckily these come in a 2 pack! I just swapped to the one I hadn't been using, and look forward to using my favorite earbuds even longer.
