Signeo USA unveiled a new set of headphones back in CES 2011 early this year called Soul by Ludacris. In case you were wondering – they are headphones that have been endorsed by one of the most famous rappers around, Ludacris. While they were shown off at the event, they weren’t available for purchase, and no prices or release dates were announced – until recently when the official Soul website was updated with the prices of the headphones. A sign that they are getting closer to the intended release date? Possibly. Either way, if you’re looking for some money to spend on artist-endorsed headphones and don’t want to get a pair of Beats by Dre because everyone has one, Soul might be for you. Touted as headphones that give you “studio quality balance of deep bass and crystal clear mids and highs”, they range from $69 in-ear variations all the way to $299 over-ear models. No word on a release date yet, but you can head over to the official Soul website to find out more details.
