Sound bars, tablets and mobile phone accessories were among the top-selling consumer electronics products sold in June 2013.
But the UK market declined year-on-year, reports GfK.
Sound bars grew 165 per cent in value during the month, compared to June 2012, due to thinner TV devices and their reduced sound capability. Meanwhile, turntables grew by 11 per cent.
However, the UK Consumer Electronics (CE) sector dipped by 21 per cent in value year-on-year.
"The summer months in 2012 showed a much more positive picture for the CE market due to the European Football Cup and the run up to the Olympics," said GfK's Anja Kraus. "These events pushed sales in the TV market, mainly in the 40-inch and above segment."
TV sales dipped 25 per cent year-on-year and the DAB segment dropped 17 per cent in value. However, car audio sales rose five per cent, clock radios were up 18 per cent and portable radios up 63 per cent.

The UK IT market fell 1.7 per cent in both volume and value in June 2013 year-on-year, with tablets taking market share away from more traditional computing areas.
Tablets rose 73 per cent in sales volume during the month, but this was tempered by an average selling price decline of 30 per cent over the same period, meaning that value growth for tablets was actually 20.6 per cent.
Desktop computers decreased in sales volume by 19 per cent and by 26 per cent in value, while notebook sales dipped ten per cent in both volume and value during the month.
"This is a significant blow, especially as this category is important in value terms to the overall IT market," commented GfK's Chris Kennedy-Sloane. "Media tablets brought in only slightly more value to the overall IT market than notebooks for the first time since December 2013. We expect media tablet sales to remain strong, with growth rates plateauing this year."
The total mobile accessories market also grew three to five per cent in value versus June 2012.
"One of the main drivers behind this increase in sales value was mobile cases," said GfK's Hannah Frost. "The year-on-year value growth that this segment has seen comes as consumers look to invest increasing amounts of money on higher specification cases to use with their mobile handset."
Mobile cases accounted for 30 per cent of sales value in the mobile accessories market in June 2013 - the highest share seen in the past 12 months.
"Within this category, there is a price polarisation of sales coming through the price points, with both the sub £10 price point and £30+ price points growing year-on-year," added Frost. "The majority of this value growth in the cases category has come through the £30+ price point, which accounted for nearly 50 per cent of all sales value in June 2013. Some smaller growth has also occurred in the sub £10 price point which accounted for ten per cent of value in June 2013."
