EPOS ADAPT 165 II (3.5mm only) Corded Headset

Please note this headset has a 3.5mm connector. Before purchasing, if you intend to use it via the 3.5mm connection with a mobile/tablet, please check that your device has this connection. Eg iPhone models 7 and above require the lightning to 3.5mm adapter. Some models come with that, some don't. If you do not have the adapter, you can purchase for $10-$20 from stores such as Kmart, Officeworks or any techy/gadget store. If you have any queries, please call our team for clarification.

Essential Info

Launch Date March 2021

The SC 135 is a ono (1 ear) corded 3.5mm jack headset for smart phones and tablets.

This version of the SC 100 series comes with the 3.5mm jack only. It does not include a USB connector or a control panel. If your mobile doesn't have a 3.5mm port, you'll need an adapter to make this work. We don't stock these.

What is EPOS? EPOS is the new co-branded name for Sennheiser.

The EPOS Adapt 100 series replaces the Sennheiser SC100s.  eg SC 130, SC 135, SC 160, SC 165.

There are about 23 different variants of this headset so it can be tricky to figure out which is which. Firstly - lt if it starts 13_ its a mono headset - ie with 1 earcup, if 16_ is a 2 eared headset with, you guessed it ... 2 earcups. A T in the name eg 160T indicates MS Teams certification. Then there's standard USB (USB-A) or USB-C, versions, with or without a mobile connections and variants with JUST a mobile connection and no USB of any description. BUT FEAR NOT! We're not called Simply Headsets for nothing - we've grouped them for you by connection type.




You're welcome and we love you too.

Digging a little deeper

Comfort - The ADAPT100 series headsets have a unique look to them. The microphone boom hides discreetly behind the headband when not in use. The 135 and 165 variants come with leatherette ear pads (you can get foam versions if you prefer as an accessory, check out the accessory tab to the right), which are larger oval shape. T cushions don't cover your ear but at 6cm x 7.5cm they are a bit bigger than average.

The headband has a little padding in it -  not a huge amount so you won't overheat on warm days (I'm talking to Queenslanders here - our pain is REAL.) For the mono version,  the headpad stopper thingy is angled in such a way that you won't pull out clumps of hear when you take the headset off.

Larisa in our office tested them out and has officially rated them 'ace' for comfort. The earcups also fold flat for convenient storage or travel and All ADAPTs come with a fairly minimalist drawstring nylon bag.

Controls - There are no controls on this headset. You'll need to use the answer,  mute and volume controls on your mobile or tablet.

Quality - As you'd expect from EPOS , the HD quality sound is great for voice and music. The microphone has noise cancelling to block out most of the noise around you for the person on the other end of the call so your most valuable client won't hear the office clown doing his (or her!) 'hilarious' impression of the boss. The mic boom is bendable so you can get perfect positioning; 2-3cm from the corner of your lips.


This 3.5mm jack version is also certified for use with Chromebook.


In short - The ADAPT 100s are definately a top pick for good quality business level communication that won't break the budget. They look swish and have all the features you need for a simple mobile phone headset.
