Smartphones and music streaming services let people take virtually infinite amounts of music anywhere, but without the Master Enhancer, peoples' cut-rate earbuds hardly allow them to appreciate it. Conceived by John Kasha, a professional audio engineer, the Master Enhancer (or m.e.) is a tiny piece of hardware that connects to any pair of headphones, making them sound like "the front row of a live concert," according to the m.e. website.
With its sleek, matchbook-sized design and attachable keychain, the m.e. is simple to carry around wherever users need music. It also offers 80 hours of battery life per charge and uses a standard USB port to charge to full capacity in as little as fifteen minutes. The Master Enhancer lets audiophiles bring their obsession with sound everywhere and anywhere.
