Sony Europe is showing off a new digital wireless RF headphone<\/a> called the MDR-RF4000 with 30 meter range and high quality sound. These piano black headphones are rather large, but are quite comfortable thanks in part to the swivel circumaural cushions and a parallel-link self-adjusting headband. This ensures comfort for your listening experience, even for long durations of time. However, they seem a little heavy at 300g, which is .6 pounds.<\/p>\n

There is also a handy volume control on the headphone so you don’t have to bother reaching for the remote. Digital RF transmission ensures clear, secure signal reception over a range of up to 30m. The headphone\u2019s closed-type design cuts sound spillage, so there\u2019s no need to disturb others while you\u2019re enjoying the action packed finale of a favorite movie.<\/p>\n

The MDR-RF4000K also comes with a stylish storage\/charging dock that goes along well with their usual minimalistic design principles. The slim, convenient storage case doubles as a cable-free battery charger. After use, just fold the ear cups flat and the MDR-RF4000K stows neatly away while the battery recharges.<\/p>\n

The power-efficient design allows up to 7 hours continuous listening time between charges of the NiMH battery. Alternatively, slip in a single AAA alkaline battery and enjoy up to 10 hours listening without a break. An auto power-save feature switches off the headphone when it\u2019s not being used, extending listening time still further.<\/p>\n
