These are some of the best and lightest over ear wireless noise cancelling headphones on the market.

They are in excellent condition, except for slight markings on the exterior of the headset (see photos). Bought new from JB Hi-fi in Wellington in October 2020, and very well looked after.

The battery lasts for hours. They can connect to two devices simultaneously. They have a companion app that helps manage noise cancelling levels depending on your surroundings (you can hear street noise when walking, for instance, but not hear any colleagues in a busy office). They can also stop cancelling noise if someone speaks to you - so you can hear them.

They fold and fit in a hard shell carry case (see photos) - meaning they can be stored/transported easily when not in use. The case also contains a recharging cable, a wire to connect them to a headphone jack and an adapter to allow use on a plane.

This model currently retails at $450 brand new. They came out in 2020 and they are the penultimate model (a new model, XM5 came out earlier this year).
