Ziggy is a songwriter and singer, and now Rohan, who has five children with musician Lauryn Hill, has taken the family tradition a step further with his House of Marley range of headphones.

After releasing in January at the Consumer Electronics Show in Las Vegas, the headphones were launched in South Africa this week.

Made from recycled and "sustainable" materials, the headphones have the styling you'd expect from the Marley legacy, featuring red, yellow and green.

As befits the musical tradition of such a famous family, the House of Marley products have decent sound, with good bass.

There are a number of ranges and styles, both in-ear and on-ear, including some that are more conspicuously Rasta-themed.

The ranges are named after famous Bob Marley songs, including Redemption Song, Stir It Up and Exodus.

The best name is arguably Positive Vibration for solid on-ear cans that give precisely that. Items in the top-end, over-the-ear set, called Destiny TTR, give great sound and are made from recycled aluminium and leather.

The House of Marley donates part of its profits to the family charity, 1love.org. In South Africa, it is working with Faces of Hope Foundation and building a music room for the Eqinisweni Secondary School in Ivory Park.

"We want to be on the ground, so we are working with a local charity and giving back on the ground," Rohan said.

In other news, Microsoft announced its own streaming music service called Xbox Music. Featuring a selection of 30 million songs, it is expected to be available in South Africa before the end of the year.

Like Spotify (which isn't available) and Simfy Africa, it is a streaming service - except it will only run on Windows 8 or Windows Phone 8 devices, as well as the Xbox 360 games console.
