M2500 from Plantronics is very well built, with easy controls and durable design. Even though the device does not sport DPS, the audio quality is very good if you do not pass the 6-7 meters (18- 21 feet) mark and you are in a quiet environment. The headset can be easily put on with one hand and even though its weight is more on the heady side (23 grams) it be worn for prolonged periods of time without creating discomfort.
