Panasonic HD-10 - Modified 💎

This headphone is severely overly-sensitive to output impedance.
Detail is excellent. Midrange tuning is garbage - shouty. Bass is 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.
