No adapter can adapt an unbalanced shared ground to a split ground for balanced sound. The only way is to buy TRRS, open up your TRS then solder it properly. Technically, you can try to use an adapter, but the ground will still be shared, which in turn is ineffective.
You will love ZX2. I can't even stand music on Note 4 or iPad anymore. It has to be ZX2 lol.
However I think it is possible to adapt split ground TRRS to shared ground TRS but not the other way around...says if you decided to solder your TRS to become TRRS and decide to use it on a smartphone TRS, you can buy an adapter for that. If it exists. Probably http://www.amazon.com/YCS-Smartphone-Headset-Microphone-Headphone/dp/B00MV2PDCA/ref=sr_1_4?ie=UTF8&qid=1437744975&sr=8-4&keywords=TRRS+female+to+TRS+stereo
