So on my trip to Japan, I forgot my nice Sennheiser CX 680 in the plane. Lucky for me I went to the electronics district here in JP and got a pair of Audio Technica ATH-CKS77X. I have to say this sound great and I can listen for hours and My ears don't get tired like they use to with CX680. Bass is good and they are not to bright.
They were too many options to choose from, believe me in the hundreds for in the ear headphones from the cheap to some costing in the thousands, too bad i did not get chance to audition some of those.
