- Does the Sony MDR-ZX110NC work without a battery?
- Yes. It plays passively through the 3.5mm cable when the AAA battery is dead or removed. Noise cancellation is off in that mode.
- How good is the noise cancellation?
- Sony rates it to reduce ambient noise by up to 95%, about 13 dB. It softens steady background sound but does not match premium over-ear ANC headphones.
- Can I use it for calls?
- No. It has no built-in microphone for calls, so it is for listening only.
- What comes in the box?
- The headphones, one AAA battery and a flight adapter for airplane audio jacks.
- Is it Bluetooth?
- No. It is wired only, with a 1.2 m cable and a gold-plated L-shaped 3.5mm plug.
- How does it compare with the plain MDR-ZX110?
- The ZX110NC adds active noise cancellation and a battery compartment. Sound and fit are otherwise similar.
