Sony MDRNC33B.CE7 In-Ear Noise Cancelling Headphones with Extra Long Battery Life

These MDR-NC33 in-ear Digital Noise Cancelling headphones from Sony let you enjoy your music on the move without the distraction of everyday background noise. Whether you're travelling, commuting or working at the office, active noise cancelling technology reduces 90 per cent of ambient noise*, providing you with a quieter environment to enhance your audio experience.

The lightweight 7 gram MDR-NC33 in-ear headphones combine style with practicality. Silicone earbuds come in a range of sizes to provide the perfect fit with minimum sound leakage. They sit comfortably in the ear, even during extended use.

Hear your music, nothing else
Advanced Artificial Intelligent Noise Cancelling automatically monitors your environment to find the right anti-noise profile. The headphones have an inside microphone on each earpiece that works with an electronic circuitry to create an opposite sound wave to reduce incoming noise. A convenient monitor switch allows you to minimize your audio and listen to conversation. When noise cancellation isn't necessary, the passive feature lets you operate these earbuds as regular stereo headphones without using any battery power.

Crisp, clear and powerful sound
The high power 13.5mm Neodymium driver found inside the MDR-NC33 headphones is super powerful, and delivers a wider frequency response to your ears - reproducing deep bass, dynamic vocals and clear treble sound. It has a frequency response of 10Hz - 22,000Hz and a sensitivity of 98dB/mW (NC ON) and 99dB/mW (NC OFF) so you can enjoy crisp, warm audio at any volume.

Turn on, switch off
If you need to interrupt your listening, to hear an in-flight announcement for example, simply flick the switch to turn off Digital Noise Cancelling. The convenient monitor switch allows you to stay aware of your surroundings, whenever you need to, then swap seamlessly back to your music.

Listen without interruptions
Enjoy approximately 100 hours of noise cancelling functionality from a single alkaline (size AAA) battery** (included) and at least 50 hours with a rechargeable battery. This battery stamina is way ahead of the competition. And if you switch the noise cancelling circuitry off you can enjoy the same sound quality without using any battery power. For long journeys, it's reassuring to know that changing batteries will be one less thing to think about.

Interchangeable silicon buds guarantee great sound isolation and total comfort.

Fits all ear sizes
When you're wearing in-ear headphones you need them to be so comfortable you barely notice them. The MDR-NC33 headphones come with three sizes of hybrid silicone earbuds (S/M/L) for a more secure, custom fit. The interchangeable buds guarantee great sound isolation and total comfort.

Listen for longer in stylish comfort
A durable and lightweight Y-type cord completes the package. The cord's 1.5m long, letting you move around and mix it up without getting in a tangle. Put all this together and the MDR-NC33 in-ear headphones are still amazingly light at around 7 grams, making them easy to wear, and carry.

Your MDR-NC33 headphones come with an in-flight plug adaptor*** and carrying pouch so you know they're ready for use and safely tucked away for your next journey.
