The entry level JPL JAC Plus has a noise cancelling microphone which cancels out background noise for your customer. Combined with the double earpiece, it has excellent sound quality and is ideal for noisy offices when you want to focus attention on the call. It has an adjustable headband to ensure maximum comfort, a flexible boom that you can adjust to suit your own preference and foam or leatherette ear cushions, so the earpieces sit comfortably over your ears.
