EarMax Pro looks the same as the EarMax, but has a different circuit, tubes and power supply. The advantages of the EarMax Pro include a slightly higher output level, more robust sound and the ability to drive lower impedance headphones such as Grados. See specs below.

EarMax is the world's smallest vacuum tube headphone amplifier. Introduced in early 1994, it has captured the hearts of many music lovers and audiophiles all over the world. Its miniature size, unique, attractive styling and smooth, accurate reproduction of music have made it a favorite with tube equipment lovers. Headphone listeners have been astounded at its performance and its affordable price. EarMax boasts an Output Transformer Less (OTL), Class A Triode design. The lack of an output transformer eliminates one additional path for the audio signal to pass through. The result is pure, clean, smooth, and most importantly, musical sound.

Although the EarMax will sound best with a high quality high level source, it will also improve the sound of portable CD players. Just hook the EarMax to the line out of the CD player and plug in some high quality headphones. You will add audiophile quality amplification and bypass the inexpensive volume controls typically found in portables.
