Product Overview

Sennheiser SC 665 Duo USB-C and 3.5mm Corded Headset

The Sennheiser SC 665 Duo USB-C and 3.5mm Corded headset aka 'The Century' is Sennheiser's premium USB & 3.5mm ultra noise cancelling (UNC) duo headset. It's designed to be used with Computer, tablet and mobile phone that use a USB and 3.5mm jack . The SC 665 headset has an duo over the head wearing style, with rotatable microphone.

Please note, this version of the SC 665 comes with a USB-C connection, this is smaller than a regular USB plug so please check your connections before purchasing. If you do need a regular USB connection you can find that HERE

The 665 is a plug 'n' play solution regardless of the platform

This is the USB-C and Mobile version. There is also a mobile only version Sennheiser SC 665 3.5mm Corded Headsetand a USB only version Sennheiser SC 660 USB CTRL Corded Headset It is worth noting the USB only version does not come in a USB-C variant

The Good

Where to start!!??? The SC600 series is the ultimate, the bees knees, the dog's.... well you get the idea - Sennheiser are pretty proud of it. But what to WE think of it? Pretty much the same actually. Sennheiser have an unrivaled reputation for all things audio and this headset is no different. If you are buying a headset for someone who wants the best corded headset that money can buy - stop reading, you've found it, just add to cart now.

The Century has HD voice clarity, an ULTRA noise cancelling microphone but is still lightweight and comfortable enough to wear all day. That ultra noise cancelling microphone means that the person you're speaking to won't hear anything but your dulcet tones. Great for dictation in a noisy office as Dragon (or other) won't get confused with the background noises - so this will minimise the error rate. As for conversations, most of our headset team wear UNC headsets (albeit wireless) so call and ask for a little over the phone demo of just how much noise it blocks out. Sophie, one of our headset experts who works from home, recently had some building work done. Diggers, drills, saws, hammer, not to mention the builders' appalling taste in radio stations - all blocked out for our clients by the Ultra Noise Cancelling microphone. No help for Sophie, unfortunately - she had a headache every day of the build! But her callers would never have known she was anywhere but a tranquil penthouse corner office.

The speakers are made from high quality neodymium so you can hear every utterance. It's 'wideband' so you won't get that flat tinny quality to the voice - the 600 series enhances the voice to sound entirely natural.

The build quality of the SC600 range is second to none; Stainless steel and brushed aluminium parts for lightweight strength, metal re-inforced headband as well as ultra sonic welded microphone housing. In addition Sennheiser as so confident in these headsets that the entire SC 600 range comes with a 3 year warranty instead of the normal 2 years - so you are you feeling the love yet?

Sennheiser have so much faith the SC600 series that they give them a 3 year warranty. Nice peace of mind!

The Not So Good

There’s really nothing bad to say about the Century.

As with any corded headset, with the Sennheiser SC600s you are tethered to your device via a cable, this can be frustrating when wires lie across your desk and get in the way of papers or drop down and get crushed & tangled under chair wheels. There are a few Bluetooth headsets with the UNC mic worth a look of you want some added freedom, give us a call or check out our top picks below

The Verdict

The Sennheiser SC 665 USB-C & 3.5mm is for staff who want the best quality sound on the market for their Computer, mobile & (most) Tablets and prefer a corded headset

Other Headsets To Consider Before Buying

If you dont need the binaural (2 ear) then you could check out the Sennheiser SC 635 USB-C . If you don’t need the ultra cancelling microphone or every bell & whistle, the SC 135 & SC 165 are both great value mid range options.

Of you want to be untethered and get bit more freedom in your life, most people these days opt for a Bluetooth option. It makes switching between devices a doddle and will improve your productivity, particularly if you don't HAVE to be at your computer all the time. Long call? Make a cuppa, answer the door, water your plants or get to your next meeting with Sennheiser MB Pro 2 UC and of course the UNC mic means your caller will be none the wiser.

We think that the MB Pro 2 UC is your best cable-free choice.
