How does the Hesh 540 ANC compare with the Hesh ANC?

The Hesh 540 ANC adds THX Spatial Audio, which the earlier Hesh ANC lacks. Noise cancelling is similar in character, so the spatial mode is the main reason to pick the 540.

Is the noise cancelling good enough for flights?

It cuts steady low-frequency noise like engine rumble and air conditioning, but voices and higher sounds come through more than on premium noise-cancelling headphones. It helps on a flight without silencing the cabin.

What is THX Spatial Audio?

It is a processing mode that widens the soundstage so movies and games feel more surround-like. It works best for video and gaming; many listeners turn it off for music.

Yes, a wired connection lets you keep listening when the battery runs out, with noise cancelling and spatial audio off in that mode.

Does it work with the Skullcandy app?

Yes. The Skullcandy app lets you adjust EQ, toggle spatial audio and check battery level.

Casual listeners who want over-ear noise cancelling and spatial audio for movies and games. Buyers focused on the quietest possible commute should compare it with Sony and Bose models first.
