The jack in my phone no longer holds the lead in so I went for some bluetooth IEMs and I am very impressed.
Got Enacfire G20 units with built in noise cancellation and I have been impressed with the sound and the fit but might be a bit too pricey for you - I paid £49.99 from Amazon.
Just a thought.
