Koss UR23i Noise Canceling Headphones vs Sony ZX110NC Noise Canceling Headphones

The Sony ZX110NC is the better pick for travel and noisy commutes: its active noise cancelling cuts ambient sound far more than the Koss's closed-back seal alone. The Koss UR23i is a simpler wired headset with an in-line mic and a 3.5 mm plug, and it never needs a battery. Build on both is light plastic, and owners of both report they hold up as budget headphones rather than rugged gear.

• Choose the Koss UR23i if you want a corded headset with an in-line mic for calls and don't want to manage a battery.
• Choose the Sony ZX110NC if you want real active noise cancelling for flights, buses or a noisy office.
