# HD-10 - Modified

This headphone is severely overly-sensitive to output impedance.

This headphone is SO good and SO bad at the same time.\
Detail is excellent. 💎💎💎💎💎\
Midrange tuning is a steaming pile of flaming garbage.  💩💩💩💩💩\
Bass is actual top tier - fast, dry, detailed. 💎💎💎💎💎\
Earpads will die quickly. 💩💩💩💩💩

I have heard this headphone sound good through only one device: Samsung Galaxy S9.

On all other tested devices, the 1-3KHz hump is pronounced. On S9, it is smoother and sounds great.
