What is the difference between active noise cancelling and passive isolation?

Passive isolation is just the shape of the headphone: in-ear tips or over-ear pads physically block sound. Active noise cancelling (ANC) also listens to your surroundings through microphones and generates an opposing wave, so it works best on steady drone — a plane, a bus, ventilation. ANC does very little against sudden sounds such as speech.

How long do wireless earbuds really last on one charge?

In-ear buds usually play for 4–8 hours, and the case adds another two to four full charges. Over-ear headphones last 20–40 hours. High volume, ANC and cold weather all cut into that — in winter expect roughly a fifth less.

Can I use one pair with both my phone and my computer?

Yes, if the headphones support multipoint: they stay connected to two devices at once and switch by themselves when a call starts on the computer. Without multipoint you have to disconnect one device manually every time.

Description

Radio listening for a trip or a power cut

The Krüger&Matz KM0836 brings AM/FM listening into a portable device for camping, travel and keeping at hand during a power cut. Adjust its telescopic antenna for available broadcasts without using a phone's mobile data connection.

Unfold the panel towards the sun

The folding solar panel provides another way to add charge when you are away from a power socket. Open it and position it towards the light; the energy collected depends on the available sunlight.

Add charge with the hand crank

The hand crank lets you generate energy manually when a socket or sunlight is not available. It gives you another option for adding charge to the radio while travelling or staying outdoors.

Choose light for the task

Choose between the torch's two brightness levels for lighting nearby surroundings after dark. The folding work light provides broader illumination for tasks such as setting up camp, making a small repair or preparing food in the evening.

An audible signal nearby

The SOS function activates an audible alarm when you want to draw attention to your location. It is a local signalling option alongside the radio and lighting functions when you are travelling or outdoors.

Use the USB-A output to charge a compatible phone or other portable device from the radio's battery. Recharge the radio through its USB-C input with the supplied cable to prepare it for your next use.
