Quick answer: A headset Y lead is usually the best option when a supervisor and trainee need to connect two wired headsets to the same desk phone or headset port. A headset splitter or doubler is a simpler adapter, but it may not give the same audio quality or compatibility. For computer-based calling, softphones or Microsoft Teams, a USB training cable or USB headset splitter is the better option.
Training Headset Splitter - Are you actively training your staff on the Phone or PC?
One of the most common products we get asked about a lot is the training headset splitter or Y training leads.
Basically the ability to train a person on the phone via 2 headsets You see, any business with more than 3 employees that relies on the Phone (that’s most of us probably) will need to train staff at some point and there is no better way of doing that than using a simple training system.
Best option for call centre training
For call centres (contact centres) and customer service teams, a complete training package is often the safest choice because it includes compatible headsets and the correct training lead. This reduces setup problems and makes it easier to support new starters during live calls.
For fixed desk phone users, a headset Y lead package is usually the right starting point. For computer-based calling, a USB training headset bundle or USB splitter is normally more suitable.
Headset Y lead vs splitter vs doubler: what is the difference?
| Option | Best for | Typical connection | Key point |
|---|---|---|---|
| Headset Y lead | Supervisor and trainee desk phone training | RJ9/RJ10 headset port or brand-specific bottom lead | Usually the preferred option for consistent training-call audio. |
| Headset splitter / doubler | Basic listen-in training | Two wired headset connections | Simple and low cost, but not always the best for audio quality or compatibility. |
| USB training cable | PC, laptop, softphone and some Teams training setups | USB-A or USB-C headset connection | Better suited to computer-based calls than a desk phone Y lead. |
| Full training package | New call centre starters or staff training rooms | Headsets plus correct training cable | Reduces compatibility issues because the parts are supplied together. |
| Wireless headset training | Wireless supervisor/trainee coaching | Compatible wireless headset base | Some systems allow a second headset to pair in conference or training mode. |
For wired headsets there are 2 very simple options:
A “Y” Headset Training splitter lead
So called because it's a “Y“ shaped lead, the bottom part of the Y goes in to the Phone and the 2 points at the top of the “Y” connect with the headsets. This is the most popular way of training people on the phone.
Desk Phone Headset Training Leads

What if you train staff using a PC, softphone or Microsoft Teams?
If your calls are made through a computer, laptop, softphone or Microsoft Teams, you will usually need a USB training cable, USB headset splitter or USB training headset bundle rather than a traditional desk phone Y lead.
This type of setup is useful for teams using VoIP software, contact centre platforms, Teams calling or cloud phone systems. Before ordering, check whether your headset uses USB-A, USB-C or a brand-specific headset connection.

Now let's talk about wireless headset training systems
You would be surprised how few people know you can actually train members of staff using wireless headsets, it's simply a matter of pairing 2 headsets to one wireless base station and putting them in either conference mode or training mode. Obviously the main advantage being, there are no wires between the trainer and the trainee.
Top Recommendation for Wireless headset conferencing:
Yealink WH64 Hybrid DECT/Bluetooth Headset
In summary There are pluses and minuses to both systems and as always it’s down to personal preferences and budget. That said, headset training should be an integral part of any business that uses the phone to help make a profit, it’s a very effective way of training staff quickly and efficiently!

Headset training splitter FAQs
What is a headset Y lead?
A headset Y lead is a training cable that allows two headsets to connect to the same phone or headset connection. It is commonly used so a supervisor and trainee can listen to the same call during training.
Is a headset Y lead the same as a splitter?
The terms are often used interchangeably, but not every splitter works in the same way. A dedicated headset Y training lead is usually designed for training-call audio and compatibility, while a simple doubler may only split the connection.
Can two people listen to one phone call using headsets?
Yes. With the correct Y lead, headset splitter, USB training cable or training package, two users can listen to the same call through separate headsets.
Can the supervisor speak during the call?
It depends on the headset training cable, phone system and setup. Some training solutions allow both users to listen, while others may allow the supervisor or trainee to speak. Check the product details or ask us before ordering.
Do I need a different training lead for Jabra, EPOS, Poly or Yealink?
Often, yes. Headset brands and desk phones can use different wiring or bottom cable connections, so training leads are not always universal. Choose the correct brand option where available or ask us to check compatibility.
What do I need for USB headset training?
For PC, laptop, softphone or Microsoft Teams calls, you will usually need a USB training cable, USB headset splitter or USB training headset bundle rather than a traditional desk phone Y lead.
