I've been trying to record audio from my Sennheiser to Android phones and tablets but cannot. Have tried Samsung Note 3, Galaxy S7, Galaxy Tab S, plus tried a Nexus 5, which are all Android. I've been using a Rode SC4 TRS to TRRS adapter as well.
I can easily record without issues on Apple products. Have tried, Mac Book, iPad MinI and iPhone 6 and all these apple products work fine with the same attempted set up as Android.
Sennheiser online support ignored my request for assistance.
If anyone can help it would be greatly appreciated.
