Audio-Technica ATH-M40x

A closed-back, 35-ohm studio monitor headphone in the beginner tier with a flatter tuning than its M50x sibling — an entry-level pick rather than a flawed one. The flat response suits monitoring and learning to mix on a budget. If you prefer a bass-forward, more consumer-friendly signature, the M50x is the pick instead.
