Reply to Headphone issues on my S4

Just picked up my S4 5 days ago and I have to say this thing is sick! I was practicing last evening and I heard some static in the headphones then the sound got distorted. I start fiddling with the plug and the sound continually became distorted and would come in and out. I assumed it was my headphone jack so i tested it out on some other sources and it worked fine. I'm only having the issue when connecting the headphones to the S4. My headphones are new and I tried different adapters just to make sure. Might be a hardware issue. I already reported to NI. Hopefully I can exchange it from where I purchased it but if not I might have to send it back but anyhow...anyone else experience this? What's the service like with NI for anyone needing repairs?
