The headset/ earbuds supplied for media use, and 2-way conversation use is the Nokia HS-47 model (2.5 mm). The newer HS-48 handsfree model is having the far more ubiquitous 3.5 mm jack connector for many of the new 'phones as they are music orientated units.

The Nokia 6650 is a great clamshell telephone and is more than just a pretty face with a 1500 milliamperes battery and just over 100 grammes in weight it feels 'proper'. Unusually, this telephone was not available from Nokia in the UK or Europe as a stand-alone purchase, and it was unable to be purchased from any cell phone vendor. It was only available from T-mobile - a T-mobile exclusive handset - and it had to be obtained on a contract basis. Also unusually, it has a 2-year warranty as opposed to the usual 12-months. In North America it appears to be available from other cell phone providers,- AT&T, and appears to be available in colours other than brushed steel. Memory card, headset phones and power-charging port are on the right side. USB port, 2 volume buttons, and the camera shutter button on the left side. The Nokia 6650 fold uses a BP-4L battery (1.5 Ah), physically larger than a standard cell battery. An extremely reliable & sturdy unit. A vanguard again, its earlier namesake of some 6-years ago, the old 6650 candybar telephone was the first 3G cell phone by Nokia. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nokia 6650 fold」の詳細全文を読む スポンサード リンク
