A special button on the right ear can now be used to activate the voice assistant to listen to favourite songs or the latest news. An additional microphone now improves voice quality. Also new is the "aptX Low Latency" decoder. And B&O wouldn't be B&O if the designers hadn't also slightly updated the look of the H4. What has remained are the memory foam ear pads, which are covered with soft lambskin leather. B&O still states a battery life of 19 hours. Also the price is unchanged: 300 Euro, from now on in matt black and from November 11th additionally in the color "Limestone".
