Section 1: Wireless Headset Solution for Snom Phones

Plantronics CS545-XD Wireless Headset:

With a headset, you instantly become more productive by being able to write and type without holding or cradling a handset  (Not to mention the reduction in neck and shoulder pain).  With a wireless headset, you take productivity up another notch being able to roam your office while talking.  Ever need to grab a file in another office or ask a co-worker a question?  You can with a wireless headset.  With the CS545-XD you get a light-weight, great-sounding headset that comes with everything you need.  

How does it work?  With the CS545-XD, you will start inbound and outbound calls at your phone.  Most newer Snom phones have a headset button on the phone.  When a call comes in, or you want to make a call, you simply press the headset ‘ON’ button and press your phone’s headset button.  You are now talking with your caller and free to roam up to 350 feet.  To answer/hang-up calls away from your desk you will need the optional EHS cable shown below.

• The CS545-XD comes from our most popular wireless headset series
• Enjoy all-day comfort with a lightweight headset (21 grams)
• 2 batteries are included for unlimited talk-time
• Includes Over-the-Ear and Over-the-Head wearing options

Optional Plantronics EHS Cable for Remote Answering:

Need to answer remotely?  If you want the most out of your headset investment, you will want the ability to answer/hang-up away from your desk.  This increases your productivity again by not missing calls to voice mail or needing to run back to your desk with every ring.  Most Snom phones allow remote answering with an Electronic Hookswitch (EHS) cable connected to your wireless headset.   Consult Section 3 below to determine compatibility with your specific model of Snom phone, and Section 7 explains EHS cables in detail.

Section 2: Corded Headset Solution for Snom Phones:

Plantronics HW540 Corded Headset:

Snom phones work great with Plantronics headsets.  You need two pieces to make it work; an H-series headset and a bottom cable.

Want to make your corded headset solution easy…with no sacrifices?  You need to consider the Plantronics HW540 EncorePro headset.  It’s a quantum leap in convertible headset design. It’s a 3-in-1 headset without compromise – all of the wearing styles are designed with quality and comfort in mind, in a system that is simple to convert but delivers a secure, positive fit and finish. The HW540 provides high-quality audio, a flexible noise-canceling mic with visual positioning guides, soft ear cushions, and durable, yet lightweight materials for all-day wearing.

• Flexible microphone for optimal voice clarity

Plantronics U10P and U10P-S Direct-Connect Cables:

Many newer Snom telephones have a headset port and button for easy headset use.  You simply plug your H-series headset into the U10P/U10P-S cable, and into your Snom telephone’s headset port.  To answer or end a call, you simply press the headset button.  It doesn’t get any easier.  If you need to walk away during a call, you keep you headset on and pull the quick disconnect apart at the U10P/U10P-S cable.  Doing this puts your caller on hold through the headset.  When you return to your desk, plug the headset back into the U10P/U10P-S cable and continue talking.  See our compatibility guide below to see which cable you need.

Section 4: Understanding a Corded Snom Headset Solution

To have a corded commercial-grade Snom headset solution you will need two items; the headset and either an amplifier or a direct-connect cable.  Headsets, amplifiers, and direct-connect cables all join together by using a quick-disconnect connection.


Quick Disconnect

The first thing to understand about commercial-grade Snom headsets is the headset cable terminates in what the industry calls a “quick-disconnect” connection.  This connection allows you to leave your headset on at all times and quickly disconnect from the amplifier or direct-connect cable when you need to walk away from your desk.


Amplifiers and Direct-Connect Cables

To connect your headset to your Snom telephone, you need an amplifier or direct-connect cable, depending on the model of your Snom phone.  As you can see in the amplifier and cable pictures, they terminate on one end with a modular clip, which will plug into your Snom phone.  

Snom worked closely with Plantronics to engineer many of their phones to have the amplifier built into the Snom telephone.  This eliminated the need for an amplifier and allowed a less expensive direct-connect cable or 3.5mm cable to be used with standard H-series headsets.  The only negative to using a direct connect cable or 3.5mm cable is you lose your ability to control your outgoing voice volume.  An amplifier gives complete volume control for your speaker and microphone.

If you feel the need for more control over your outgoing voice volume, you can opt for an amplifier.



Section 5: How Corded Headsets Work with Your Snom Telephone

When using a corded headset on Snom telephones, most phones will use a headset with an amplifier or direct connect cable.  Snom has worked closely with Plantronics and designed their newer phones with the amplifier built into the phone, so only a direct-connect cable is needed with a headset.


Typical Setup Using Amplifier:

If using any H-series headset and amplifier, the amplifier will plug into the headset port on your phone.  When you initiate a call, you simply press the headset button on your phone.  When finished with the call, you will press the headset button again on your phone to end the call.  You will have a wide variety of headsets to choose from including noise-canceling models for use in a loud environment and voice-tube models for a quieter environment.

Typical Setup Using a Direct-Connect Cable:

If using a Snom phone with a headset port, you can most likely use any H-series headset with a Snom compatible Direct-Connect cable (See our compatibility chart).  The cable will plug into your headset port, and you simply press a ringing line to answer and the ‘headset button’ to disconnect the call.  The advantage of using a direct-connect cable versus an amplifier is cost.  The cable will be $28.50 versus $72 for an amplifier.  The disadvantage of using a direct-connect cable is it only works on compatible phones, and you can’t control your out-going voice volume.  If you’re soft spoken, your caller will have a hard time hearing you.

Section 6: CS500 & W700 Wireless Headsets Available for Snom Phones

In an earlier section, you learned Plantronics wireless headsets are compatible with Snom phones.  To get into more details, you have two families of wireless headsets from which to choose.  


The CS500 series is the standard version of wireless headset that connects to your Snom phone.  This series works well if your only mode of communicating within the office is through your Snom phone.  You have four basic models from which to choose with different wearing styles.  All-day comfort and great battery life will get you through the busiest of work days.


The Savi W700 series of Plantronics headsets not only connects to your Snom phone, but also to your PC and Bluetooth phone.  This allows you to keep one headset charged and ready for use no matter which way someone tries to contact you.  This is a great convenience, combining three headsets into one.  If you need to join a webinar or listen to online training, you simply press the PC button on the base, and your headset becomes your audio device for your PC instead of blasting the office with your external speakers.  The Savi headset is also there for use with your mobile phone while in the office (you cannot use the headset with your mobile phone outside of the range of the base).  The Savi headset wearing style choices are the same as for the CS500 series.  The base is what’s upgraded to support two other communication points (PC & Mobile Phone).

With both solutions you can also gain remote answer/hang-up capabilities with an optional EHS cable.

Section 7: Remote Answer and Hang-up For Wireless Headsets

Wireless units give you freedom, and adding an EHS cable allows greater productivity by allowing you to answer and hang up calls remotely.  The EHS cable will sense when your phone is ringing and will generate beeps in your headset to alert you to an incoming call.  If you choose to take the call, simply press the Call Control Button on your headset to answer the call.  Your phone answers the ringing line, and you can begin talking.  When finished, just press the Call Control Button again to disconnect the call.  You will need to return to your phone to press the appropriate buttons to dial, transfer a call, or to perform any other phone functions.  Having the ability to answer remotely greatly increases your productivity.  You can answer away from your desk and carry on conversations wherever you need to take them.  It also allows you to answer calls that would have normally gone to voice mail.  This saves you a tremendous amount of time playing phone tag with customers or co-workers.
