MDR-NC300D	Sony NC300D digital noise cancelling headphones

The Sony® MDR-NC300D headphones use Sony’s groundbreaking digital noise canceling technology in a comfortable earbud design to produce incredible noise reduction and pristine quality audio. Sony’s exclusive digital signal processing technology reduces up to 98.4% of ambient noise (at 160Hz) from airplanes, trains, or at the office.

Noise canceling technology

Noise canceling headphones reduce ambient noise and provide a quieter environment to enhance audio entertainment. The headphones have a microphone inside each earpiece that works with electronic circuitry to reduce ambient sound by synthesizing with a sound in opposite phase produced by the noise canceling circuit.

Highest Quality Noise Canceling

Reduces up to 98.4% ambient noise (20 dB at 160 Hz) when noise canceling circuit is activated.¹

Artificial Intelligence (AI)

Automatically selects the optimal noise canceling mode based on intelligent analysis of environmental ambient noise.

16mm Driver Units

Drivers work with the digital sound enhancer to deliver wider frequency response and superb sound quality.

Convenient Operation

Easy-to-reach volume and built-in monitor function on the controller allows you to hear surrounding sound without taking off the headphones for in-flight announcements or conversation.

Ergonomic Design

Vertical in-ear style housing and seven ear pad sizes for secure, personalized fit.

Selectable Sound Mode

Select Movie, Bass, or Normal listening mode based on your listening needs.

Battery

Uses single AA battery for up to 16 hours of listening time.²

Accessories

Carrying case, in-flight plug adapter, neck-chain style cord with controller (3.9 ft), extension cord (0.6m), cord adjuster, and AA battery included.

1.Total noise suppression ratio is approx. 20 dB (when the noise canceling function is on) and approx. 7 dB (when the noise canceling function is off). The total noise suppression ratio is the difference in noise energy when the Noise Canceling function is active and when not wearing the headphones. For further details about the total noise suppression ratio amount for each mode, refer to the Product Information booklet.

2.Actual battery life may vary based on product settings, battery, usage patterns and environmental conditions
