Mobile phone firm Sony Ericsson has reported a 54 per cent increase in quarterly profits.
But the 220 million (£149 million) the London-based firm made in the last three months is behind comparative returns experienced in 2004/5 and 2005/6.
On a year-on-year basis Sony Ericsson, the world's fourth-largest mobile phone manufacturer, said its revenue had grown 59 per cent.
According to the firm's president Miles Flint, the sale of nine million Walkman phones in the same period had consolidated Sony Ericsson's leadership in the music phone market.
"Sony Ericsson has continued to capture market share in a more competitive market place with a product offering that addresses a wider consumer audience than ever before," he claimed.
"Our financial results for quarter two 2007 reflect our direction to build our brand in key imaging, music and multimedia categories with a portfolio that includes more competitively priced phones."
