Question [Q] Need Slim 3.5 mm Adapter for Spigen Neo Hybrid Case

Hey,

I bought a Spigen eo Hybrid case for my Nexus 5. I like to use Sennheiser headphones with it for music playback the 90 minute trip on the transit each way to and from work. Trouble is the headphone jack doesn't fit the recessed hole in the case.

I thought I could find a 3.5 to 3.5 slim adapter for them but the only thing after an hour of Googling is a 3.5mm to 3.5mm slim IPhone audio adapter.

Any suggestions on what I can do other then buy a headset?

Peace...
