I'm sure it is just a coincidence

Earbuds at Dollarama

Beats is one of the best known brands in audio. Founded by Dr. Dre and Jimmy Iovine, in 2014 Beats was purchased by Apple for $3 billion USD.

And like any leading brand, Beats has spawned imitators. Some firms are producing outright counterfeits of Beats products, while others, such as Dollarama, are mimicking the "look and feel" of Beats products.

The shape and colour of these $3.00 earbuds is obviously meant to resemble Beats. But the design is far enough from the original that Dollarama will likely avoid legal action.

And though the exterior is similar to the Beats products I doubt that the sound will resemble the original. But for $3.00 what do you expect?
