I had THX-00 3 months and Bass doesn't improved in quantity, if it won't change by time I will contact Massdrop.:eek::confused_face_2::(

I don't heard bass crazy, bass was the weak quantity from first day. Bass quantity easy comparable with my open back Grado SR225 except better bass texture quality on THX00. I tryed now with my Samsung Galaxy S5 and was same quantity/quality bass. Is posible what my headphone pair is defected...

Hello guys, I have a Fostex TH-X00 and Grace design m9xx, my burn in period is about 100 hours. 70hours music and 30 hours pink noise/ frequency sweeps. I don't feel that this headphones have great, big bass. Is like a open back headphone bass. What is the problem with bass? Any ideas to tight...

I will sell too, if It won't change to my liking :)

Today I notice little diference, now trebles is smoother, more detailed. Mids tighter and fuller, bass tighter too, lower boominess. I am hope my cans, day to day will come for my liking than previously :)

What you think about my experience with TH-X00, I send this message to one headfier who had TH-X00 and again post to forum. Whats wrong? :D ,,I downloaded JLab burn-in file 10minutes file I don't remeber but is there (PINK NOISE +~1min./SILENCE~1min./BROWN NOISE i don't remeber/SILENCE ~1min./...

mids will change? I don't like vocals screaming sometimes, and is not natural.. trebles is uncontroled, I won't found good clarity. Everything will change in time? Now I plug 2 usb micro cables first to rosette, second to my Galaxy S5

Hello, Head-fi'ers, I got my Fostex TH-X00 pair a week ago. First impresions was quiet good. Every day of using my cans sounding better and better by slight. 3 days ago, I tryed JLab audio burn in 10minutes (Pink noise/pause, white noise/pause brown noise/pause and etc..) file. I made playlist...

.

After 3 hours of listening, I notice improvements. Everythink is little clearer, little more detailed, instruments seperation better. Bass'es now has little more punch, but still is too shy with my S5.

Finally i got my headphones, I unbox and wow, very gorgeous headphones. I plug into my Samsung galaxy S5 and it's sounds quiet good. I hear what this headphones changes drastically after burn-in. I have a question how to burn-in these beauties correctly?
