Our Verdict

Sennheiser HD 25

AIAIAI TMA-2 DJ

The AIAIAI TMA-2 DJ and the Sennheiser HD 25 headphones are designed for DJs or fans of on-ear designs and swappable cables. The AIAIAI sound more bass-heavy and warm with very de-emphasized mids and treble. Their design is modular, and you can swap out and replace nearly every component of the AIAIAI with other parts, but as is, they're less comfortable, and you can't pivot the ear cups at all. The Sennheiser cans offer a bump in the high-bass with a clearer mid-range and brighter treble, which is more versatile, but it can depend on your tastes. The unique splitting headband allows them to fit with better stability and comfort. The Sennheiser are the better pick for most DJs. Still, if you're a bass head, the AIAIAI are the better choice.
