Accompanying the Lumia 625, Nokia also announced a range of 3 headsets today called the Coloud Boom, Knock and Pop. All three headsets are available in yellow, red and cyan and will be available in September for 27 Euros, 22 Euros and 18 Euros respectively. The Boom and Knock are over-the-ear headphones while the Pop is a pair of in-ear noise-isolating earphones. The Boom is the largest of the three with a closed design while the Knock is slightly smaller. All three sport an integrated microphone and control button, as well as flat cables with a cable-management feature called the Zound Lasso to prevent tangles, which looks like a very intelligent design feature.
