Wireless Noise Cancelling Headphones with Rotary Knob - KA-511
SKU: CP-3447
Product Description
Built for life. Built for you.
The KA-511 looks as good as it sounds. It has smooth, rounded ear cups with a matte finish, a padded headband and a rotary knob that makes the controls easy to use. Add Active Noise Cancellation and Bluetooth 5.4, and you get a pair of headphones you’ll want to wear every day.
Turn, press, done
Instead of fiddly buttons, the KA-511 has a rotary knob on the ear cup. Turn it to change the volume, press it once to turn noise cancelling on or off, and double press to skip to the next track. It’s easy to find without looking, even on the go.
Turn down the world
Active Noise Cancellation reduces background noise by up to 20 dB. That’s enough to take the edge off traffic, chatter and air conditioning hum, so your music comes through clearly. A green light shows you when ANC is on.
20 hours of playtime
A full charge gives you up to 20 hours of listening. When it’s time to recharge, plug into USB-C and you’ll be full again in about 2 hours.
Sound you can feel
The 40 mm drivers give you deep bass and clear vocals, whether you’re listening to your favourite albums, a podcast or a show on your tablet.
Comfortable all day
Thick, cushioned ear cups sit around your ears instead of pressing on them, and the padded headband spreads the weight evenly. They’re comfortable through long listening sessions.
Quick to connect
Pair once and the KA-511 reconnects to your device every time you switch it on. Bluetooth 5.4 gives you a stable connection up to 10 metres away.
Hands-free calls
Press the power button to answer or end a call, or hold it to reject one. Your phone can stay in your pocket.
Wired backup
If you can’t use Bluetooth, plug into the 3.5 mm AUX jack and keep listening.
