So i bought the wrong amp to join the high impedance earbuds train pretty dissapointed but yeah nx3 is just another entry level amp ...
What kind of earbuds that i can listen to its best with nx3 mate? Should i forget about earbuds that have higher impedance than my current seahf smart 1.0 150ohm?
I'd say with nx3 in theory less than 150ohms earbuds would be driven very well. If you keep nx3, you should look for earbuds that don't require too much power, Shozy Stardust maybe
If you really want very high impedance earbuds, you will have to buy an other amp to do them justice. By example, I know someone has ty400 with nx5 and is very happy with it.
