While the upper class of audiophiles used to hoard high-end equipment, a modern reincarnation of Robin Hood has designed his own top quality take on headphone amplifiers and shared it with the masses. Based on NwAvGuy’s open source design, the Mayflower O2 Headphone Amp piles years of research into one highly functioning piece of equipment, converting your so-so audio into real live music.

Cut Through Controversy

The O2 was made for benchmark performance at an entry level price. Famed Head-Fi suer NwAvGuy spent a tremendous amount of time designing the O2, resulting in an impressive piece of equipment with truly objective power. The first DIY units went out for review and sparked a wave of controversy, but once the controversy subsided, the O2 was left standing as one of the best headphone amplifiers available below $500.

Sail the Mayflower

Making the most of open source, Mayflower picked up the design and made their own version. Their resulting product, the Mayflower O2 Headphone Amp, is renowned for its high-end sound, exceptional build quality, and excellent price. Every unit comes with an 1/8” input, but you can choose between an 1/8” and 1/4” output at check-out.
