Im thinking about getting an IEM for portability use ( I know it sounds stupid) like when im walking or in the public transport. But im having trouble choosing an IEM. The first category I decided to focus on is price. Since this is my 1st IEM I don't really wanna spend so much as im not sure if an IEM would be totally for me, so im looking for an IEM that is less then 200$. But from where do i go afterwards? I like hip hop,rock,edm music and also i don't really have a portable amp to power up an IEM so i gotta make sure that this IEMs can be powered by my phone (samsung s8 edge). Any IEMs or features i should look out for afterwards??
