Headphones, anyone?

Here is another amazing signboard in Pune.

Often there are one or two mistakes in the brand names, but this guy obviously has no regard for accuracy. ALL brand names but one are wrongly spelt. Or juuuust in case, I wonder now, if this is actually a marketing ploy? Although going by the location of this board in Pune, that would be a rather far-fetched expectation.
As of now, I am surely deferring my plans of buying headphones..... I presume these will come with a statutory warning. Listening to music can cause serious injuries to the ear!
