Headphone specialist Sennheiser tomorrow (July 20) will run the second round of its Dare to Compare campaign in five HMV stores.

The campaign, being run in-store and in social media, challenges shoppers to compare their existing headphones with Sennheiser’s.

Customers are encouraged in-store by discounts on selected products on the day and a social media competition offering prizes to those who visit the Sennheiser stand and upload photos to Sennheiser’s pages on Facebook and Twitter.

The HMV stores selected to host this year’s Dare to Compare campaign are in Manchester, Birmingham, Oxford and two in London – in Oxford Street and inside the Piccadilly Circus Trocadero entertainment complex.

The stores, said Sennheiser, are hoping to see similar result to those achieved when the campaign was trialled at HMV’s flagship store in Oxford Street in November.

“Along with impressive sales figures came encouraging customer feedback,” said Sennheiser.
