Verdict

The Plantronics .Audio 355 is a wired multimedia headset featuring 40mm neodymium dynamic drivers that deliver a full-range frequency response of 20Hz–20kHz and 32-ohm impedance for resonant stereo sound with enhanced bass. Designed for versatile computer use, it includes a noise-canceling electret microphone on a telescoping QuickAdjust boom that rotates out of the way when not in use, supported by a 3-metre cable with integrated in-line volume and mute controls. Main advantages include its lightweight, flexible frame with pillow-soft leatherette ear cushions and clear voice transmission for VoIP applications like Skype; however, some users have noted cons such as a tight fit that may become uncomfortable during long sessions, small ear cups that sit on rather than over the ear, and potential durability concerns regarding the microphone boom over extended use.
