How does the noise cancelling compare with Sony's WH-1000XM models?

The MDR-ZX110NC is a basic on-ear set that targets low-frequency noise only. The WH-1000XM over-ear models cancel a much wider range, including voices, and add Bluetooth, a mic and app tuning. The ZX110NC is the simpler, wired option.

Does it need a battery for noise cancelling?

Yes. Active noise cancelling runs on one AAA battery, separate from the audio signal. With the battery dead or removed, it still plays as a normal wired headphone.

Can I use it with a phone that has no headphone jack?

Only through an adapter or a device with a 3.5 mm output, since the cable is fixed and there is no Bluetooth. It works directly with laptops, tablets, players and in-flight systems that have a jack.

Is it good for phone calls?

No. There is no microphone, so calls need the phone's own mic or a separate headset. It is built for listening, not talking.

What comes in the box?

The headphones with their attached Y-shaped cable, plus a AAA battery for the noise cancelling. A carry pouch is not included.

It is an on-ear design with a folding, swiveling headband. The pads rest on the ears rather than around them, so fit depends on head size and some users find pressure after long wear.
