Keyscaper KHDBT2

Wireless ANC Over-Ear Headphones

Everything you need to get going, plus an honest account of what these are good at and what they are not.

The full manual is on its way.

It is being finalised right now. Everything you need to get going is on this page, and if you want the complete document today, email support@keyscaper.com and we will send it straight over.

Quick start

Power on: Hold the power button until it says "power on". If it has nothing to connect to, it follows with "pairing" and starts looking.
Pair with your phone: With the headphones in pairing mode, open your phone's wireless device settings and pick Keyscaper KHDBT2. On Android that is Settings, then Connected devices, then Pair new device.
Two devices at once: Pair the second device the same way and leave both connected. Music plays from one; a call on the other interrupts it and hands back when you hang up. You do not have to tell it which is which.
Noise cancelling: The ANC switch works on its own. It does not need a phone, a connection, or the music side switched on at all, because it is a separate circuit. Green light means it is running.
Wired: The 3.5 mm cable is fully passive. It works with the headphones switched off and with the battery flat. Note that plugging the cable in powers the unit down, so there is no noise cancelling while you are wired.
Game mode: Hold play/pause for three seconds to switch between Music mode and Game mode. It starts in Music mode.
Charging: USB-C. About 35 hours of playback per charge with noise cancelling on, at full volume, which is how we measured it.

Table of Truth

a.k.a. Real Talk. What these do well, what they will put up with, and what they were never built for.

Music

Solid40 mm drivers, SBC/AAC, 20 Hz - 20 kHz. Competent and clean.

YMMVGroup listening? More like silent disco.

NopeRemastering the White Album. No LDAC or aptX, so no hi-res story.

Sound isolation

SolidSteady, low-frequency, periodic noise. Engines, cabins, HVAC, road drone. This is what feedback ANC is for.

YMMVConversations, clatter, anything spiky and irregular.

NopeThe shouty HR situation in the next cubicle.*

Gaming

SolidCasual, mobile, solo gaming, with Game mode on.

YMMVBoard games? Usually better to pay attention for those.

NopeRaid night on Discord, in a noisy bar, timing headshots.

Travel

Solid226 g, folds flat into a genuinely small case. 35 hours a charge with the cancelling on.

YMMVMars. We've never been. Let us know?

NopeThat's a bad idea. Don't bike with headphones.

Voice and calls

SolidRocking out, then taking a quick call. It hands over, and hands back, on its own.

YMMVZoom, three-way calling, chatting with your family.

NopeDeftly juggling all your bosses at the same time.

Really nope Hearing protection. Seriously, these aren't for that.

* Nothing electronic is gonna make THAT go away.
