Frequently Asked Questions

If you require any help with choosing the most suitable headset please call for advice and further information on all of our products. JPL is there to help you make the right choice. Check the answers to some of the frequently asked questions we receive, but remember, if in doubt, give us a call and we will guarantee to get you the right headset.

There are many types of wired headsets, USB wired headsets, RJ11 direct plug-in headsets, 2.5mm jack direct plug-in headsets, 3.5mm jack direct plug-in headsets and Quick Disconnect (QD) headsets. All of our QD telephone headsets require a selectable bottom lead in order to connect to your telephone system. We supply our own branded leads for this purpose, ensuring compatibility with all major telephone manufacturers and their products. Please be sure to check the details and information on our Compatibility Tool before ordering, or call directly for further advice.

All JPL Telecom products are manufactured to the highest of standards, and carry a minimum 12-month warranty. Please see our returns policy for information in the unlikely event of a fault or issue with any JPL Telecom product.

What are the benefits I'll get from wearing a headset?

With hands free, you will find typing and writing much easier whilst on call. Not having to clamp the phone between your ear and your shoulder will greatly reduce muscle strains that often lead to head, neck and back aches. Allows you freedom of movement and encourages you to sit more naturally. Overall, this ability to multi-task in comfort will lead to more productivity and save you time, which increases productivity and business.

Monaural, binaural - what's the difference?

Put simply, monaural headsets have one earpiece, binaural have two earpieces, and Monaural headsets tend to be the most popular as they offer excellent security to the head and ear, however, in some circumstances such as noisy environments or occupations which demand highly focused call-taking, binaural headsets are sometimes preferred as they offer sound in both ears.

Do I need to have any additional equipment other than the headset?

A lot of office phones are now supplied with a headset socket or are headset programmable, so all you need is the headset. However, some are not, and in these situations an amplifier is required which plugs directly into the existing handset socket which then allows both the headset and the handset to be used. Also available are training devices, which enable two headsets to be connected to a small box unit that can also be connected to the existing handset socket, with a mute button the supervisor can take control of the call at any time.

What is noise-cancelling technology?

JPL Telecom headsets are fitted with noise-cancelling microphone technology; this results in a dramatic reduction in background noise being transmitted down the telephone line when calls are made from a noisy, busy environment. This not only makes your calls sound more professional but can also cut down on the need to repeat yourself due to your caller not hearing you clearly.

What is a "bottom lead"?

JPL Telecom Wired Headsets are designed as a modular two-part solution so in addition to the headset you will need a separate "bottom lead" in order to connect to a phone or other device. The headset has a cable that ends in a "Quick Disconnect" which is a proprietary connection. To connect to a phone or device you will need a "bottom lead" which has the "quick disconnect" on one end and on the other end is the connection (RJ11, 2.5mm jack, 3.5mm jack or USB) for the phone or other device.

How do I connect my wired headset to a desk phone, mobile phone or computer?

JPL Telecom Wired Headsets are designed as a modular two-part solution so in addition to the headset you will need a separate "bottom lead" in order to connect to a phone or other device.
The headset has a cable that ends in a "Quick Disconnect" which is a proprietary connection. To connect to a phone or device you will need a "bottom lead" which has the "quick disconnect" on one end and on the other end is the connection (RJ11, 2.5mm jack, 3.5mm jack or USB) for the phone or other device.
The headsets are designed like this because different phones jacks are wired differently and have different sensitivities and will sometimes require a different connection. Having a modular system allows for the option to have different "bottom leads". This way if something changes only the "bottom lead" (which is less expensive) would need to be replaced rather than needing to replace the entire headset. Different cables for different devices (like a mobile phone or computer) exist so the headset is able to be used on different devices. You can use the same headset for your desk phone, mobile, computer or laptop just by changing the "bottom lead".
To select the correct "bottom lead" go to our Compatibility Tool to select the appropriate phone make and model and the style of headset and you will be shown the correct "bottom lead" and other accessories needed to connect your headset to your device.

Can a wired desk phone headset be used with a USB connection?

Any JPL Telecom Office & Contact Centre headset model with an “Quick Disconnect” can be used to connect to a USB port by utilizing a “bottom lead” with a USB connection.
JPL Telecom offers five (5) “bottom leads” with a USB connection:

  • BL-05NB (plain (no buttons) lead)
  • BL-051+P (lead with integrated control box with mute and volume control)
  • BL-053+P (lead with integrated control box with mute and volume control)
  • BL-05MS-P (Microsoft approved lead with integrated control box with call/accept mute and volume control)
  • BL-054MS-P (Microsoft approved lead with integrated control box with call/accept mute and volume control)

How do I set up the training lead connections for a wired headset?

The training lead for JPL Telecom wired headsets is a "Y" shape with three (3) sections. One section is the "trainer" section, one section is the "trainee" section and one section is unlabeled.
Coming out of the phone is the "bottom lead" that ends in a "Quick Disconnect" and this "bottom lead" would usually be used to connect the headset to the phone. The short unlabeled section of the training connects to the "bottom lead" coming out of the phone.
Once the training cable is connected to the phone there is now the "trainer" and "trainee" sections open and waiting for headsets to be connected. It will depend on the training set up as to which headset will be connected to which cable. The "trainee" section is always active and intended for the headset of the person who will be talking during the call. The "trainer" section of the cable includes a mute switch so the person connected to the "trainer" section will only listen to the conversation unless the mute switch is deactivated to allow the person to participate in the call.

Why are JPL Telecom headsets lower priced than the leading brands?

You are dealing directly with the manufacturer. This means that JPL's pricing is on average 25% cheaper than the brand leaders' like-for-like products. Typically, the microphone and speakers are to the same quality and in many cases are made by the same subcontractor. This means that end users are paying high premium from the current brand leaders for different styles and the brand name only. This is why every year JPL is now gaining significant market share with more and more resellers and end users realising this and switching to the JPL brand for like performance with significant cost savings. We say "A headset should NOT cost more than a typical office phone!"
