Sennheiser SD Office ML (506009) Wireless Headset - Single-Sided DECT Headset for Desk Phone & Skype for Business with Noise-Cancelling Mic, Adjustable Headband (Black) | Perfect for Office Calls, Remote Work & Business Communications

Pros:As a business device, this product excels.The reception range is amazing.The battery life is great.It's very lightweight and doesn't hurt to wear for long periods of time.When using the headband, the earpiece is capable of swiveling seemingly over 270° for use on either ear.Regardless of being "certified for Microsoft Lync" it's still recognized by Windows as a plug & play device and it's seemingly usable with any application capable of audio.Cons:The Mute LED is on the product's charging stand, instead of on the tip of the microphone where it's visible to the user. This means that whenever the user is away from the charging stand, it's impossible to determine the hardware mute state without pressing the mute button to listen for the mute/unmute tone.The charging stand is just what it sounds like--a stand. In comparison with other headsets, which require only a USB dongle and a charge cable, this is a lot of hardware to cart around and is not suitable for business travelers.The device is intended for call center use, and unsurprisingly the audio quality is very low. This was probably an intentional design decision to maximize battery life, but it makes this device a poor fit for mixed work/recreational use.On-board mute button is a plunger design on the volume up/down switch, and an incredible amount of the scraping sound it makes against its housing is transmitted through the microphone to the call recipient. It is impossible to quietly mute using hardware alone.The Volume up/down control is oriented up/down, which makes sense when wearing it on the right ear. However, when flipping to the left ear the user must remember that the volume control is now upside down. It would have been better to orient it along the axis of the microphone arm.Overall: A great buy for the stationary 9-5 office worker. Look elsewhere if you have to travel or if you want to use it off the job.I bought this for my wife for her birthday. We both work from home and she's constantly in meetings all day long. Previously she had a corded headset and she could never leave her desk to get coffee, etc. Now she's able to multitask and move around with this cordless headset!Came wrapped in news paper with no instructions! If using a actual phone leave the phone off the hook and connect it into the white part of the phone green goes into the back of the phone! I love it besides no instructions and how it arrivedWe got a few of these to replace our aging headsets at the office. They have good wireless range for when you get up from your seat while on the phone with a client. The noise cancelling is great. Our clients no longer complain about background noise when other reps are talking too loud next to each other.This is my second unit, first one lasted 2 1/2 years. Great unit for hands free office work.Super easy to set up. Plug in, tweek a couple buttons on the bottom of the base and away you go.Sennheiser also offers great support and batterys are available locally if you need them.I highly recommend this product.The head set works great with good sound and configured with two phones (Cisco and Yealink) easily by adjusting the switches. Moving back and forth from a PC video chat or a telephone chat is seamless.Great productA little overpriced I think
