5.0 out of 5 stars Outstanding Solution!
By Taylor Moore on June 18, 2016
I purchased this extender to allow me to listen to my Custom In Ear Monitors on my iPhone with the Apple Extended Battery Case. I was so sad when i bought this case and realized I would need to buy a new cable for my phone to work with it. Well, this was a MUCH better and cheaper solution!
There is a slight bit of resistance from the case due to the length of the thin portion of this connector. It is a perfect fit, but it's really close. Right before it inserts into the headphone jack, there is a tiny bit of interference with the case. It's not enough to cause any issues, although if you pull lightly on it, you can feel that an "outward force" exists on the extender due to the case.
I also tested the sound quality using this extender vs no extender using Jerry Harvey JH13 $1200 in-ear monitors... if there was sound degradation, I would absolutely hear it. This does not affect the sound in any sort of noticeable amount. If there is degradation, it is not audible to the human ear. This was a big relief for me as an Audiophile. I used The 1975 - "I Like It When You Sleep, For You Are Beautiful Yet So Unaware of It" as my test track. Great frequency range to listen for any degradation and all checks out!

All this said, it works well, it IS compatible with the Apple Extended Battery Case.

5.0 out of 5 stars Premium build
By Concerned Citizen on September 10, 2016
This is not a biased review since I purchased this product with my hard-earned money. It was not offered for free.

This is my first time buying such an adapter. I had to buy this because the splitter and the earphone themselves didn't fit my Note 3 with a Spigen Hybrid case. So should I buy a new earphone and splitter? No! I'm glad I found this. This has a lot of good reviews.

From the pictures, it's almost 4.5 cm long. It's thin and very well made. I immediately tested it and it worked. Sound was still good. You need to make sure you push the earphone or splitter all the way in until you hear a click. I think this will survive a long time of usage based on the material.

5.0 out of 5 stars It's good quality long lasting extension.
Reviewed in the United Kingdom on February 7, 2019
Edit: The first one I received was faulty. I bought a bendable extension as a replacement (lasted a week) and then I bought 3 pack of these ones again. It has been working fine for 5 months now. Yay!
___________
The aluminium (?) outside part kept on sliding off revealing insides made of white plastic. I thought because it's not bendable it's going to last longer than regular cable-made, bendable extension but instead, when I dropped my phone while using it, it bent in two places (both in the plastic part and the audio jack part).
