Every headset featured is available from Headsets4Business with a free no-obligation trial.
What connections do Yealink T4 series phones have for headsets?
The Yealink T4 series supports four headset connection methods. Which ones are available depends on the specific model.
USB ports (all T4U and T44W models) — all T4U models have dual USB ports. These allow direct connection of USB wired headsets — plug in and the headset works immediately with no additional setup. The dual USB design means a headset can occupy one port while a second USB accessory uses the other. USB is the simplest and most reliable connection method for T4 series phones.
RJ9 headset port (all T4 models) — the traditional circular headset socket. Requires a QD wired headset with an RJ9 interface cable. While functional, for T4U and T44W owners a USB wired headset is generally the better choice as it is simpler to set up and provides better audio integration.
Bluetooth (T44W built-in; T4U models via BT41 dongle) — the T44W has built-in Bluetooth 4.2, allowing direct pairing of Bluetooth wireless headsets without any additional hardware. On all other T4U models — T42U, T43U, T44U, T46U and T48U — Bluetooth headset use requires a Yealink BT41 Bluetooth dongle plugged into one of the USB ports.
Note* If you purchase another brand of headset, the dongle will be included e.g. Jabra or EPOS etc
EHS port (all T4 models — EHS40 adapter) — the Electronic Hook Switch port allows a DECT wireless headset to answer and end calls remotely from the headset without touching the phone. The T4 series uses the EHS40 adapter for most compatible DECT headsets. Note: the Yealink WH68 range requires the EHS62 adapter rather than EHS40 — confirm which adapter is needed before ordering any DECT wireless headset.
Note* The EHS adapters above are Yealink products for yealink headsets, all other headset brands will have an equivalent EHS adapter.
| Model | USB headset | Bluetooth headset | RJ9 wired | DECT wireless (EHS) |
|---|---|---|---|---|
| T42U | Yes (dual USB) | Via BT41 dongle | Yes | EHS40 (EHS62 for WH68) |
| T43U | Yes (dual USB) | Via BT41 dongle | Yes | EHS40 (EHS62 for WH68) |
| T44U | Yes (dual USB) | Via BT41 dongle | Yes | EHS40 (EHS62 for WH68) |
| T44W | Yes (dual USB) | Built-in Bluetooth 4.2 | Yes | EHS40 (EHS62 for WH68) |
| T46U | Yes (dual USB) | Via BT41 dongle | Yes | EHS40 (EHS62 for WH68) |
| T48U | Yes (dual USB) | Via BT41 dongle | Yes | EHS40 (EHS62 for WH68) |
Which wired headsets work with Yealink T4 series phones?
USB wired headsets are the simplest and most reliable headset option for T4 series phones. All T4U and T44W models have dual USB ports — plug a USB wired headset into either port and it connects immediately. No pairing, no charging, no battery management.

Which wireless headsets work with Yealink T4 series phones?
Wireless headsets connect to T4 series phones in two ways — via DECT using an EHS adapter for remote call answering, or via Bluetooth using either a BT41 dongle (T4U models) or the T44W's built-in Bluetooth. Both allow the user to move freely during calls without being tethered to the desk.
Yealink WH64 DECT and Bluetooth Hybrid — from £141.59 ex VAT (1-ear) / £169.59 ex VAT (2-ear)
The WH64 connects to the T4 series via DECT using an EHS40 adapter, enabling remote call answering directly from the headset. It also connects to a laptop or mobile via Bluetooth simultaneously — allowing the user to switch between their desk phone and other devices without disconnecting. Up to 35 hours DECT talk time, Teams certified, available in 1-ear or 2-ear. The EHS40 adapter is required for remote call answering — confirm availability when ordering.
Yealink WH68 Dual DECT ANC Teams Headset — from £123 ex VAT (without base) / £149.99 ex VAT (with charging base)
The WH68 Teams is Yealink's current-generation DECT wireless headset with Hybrid Active Noise Cancellation and Acoustic Shield 3.0 technology — four microphones that cancel background noise for both the wearer and the caller. DECT and Bluetooth dual mode, up to 32 hours talk time, up to 90 metres wireless range in DECT mode, busylight indicator, and Microsoft Teams certified. Connects to T4 series phones via DECT — an EHS62 adapter is required for remote call answering from the headset.

Yealink WH68 Dual DECT UC Headset — from £123 ex VAT (without base) / £149.99 ex VAT (with charging base)
The UC version of the WH68 is identical in specification to the Teams model — Hybrid ANC, Acoustic Shield 3.0, DECT and Bluetooth dual mode, 32 hours talk time, 90 metre DECT range, busylight. The difference is platform certification — UC covers Teams, Zoom, Google Meet, and other UC platforms, making it the more flexible choice for organisations running multiple communication platforms. EHS62 adapter required for remote call answering on T4 series phones. Available without base at £123 ex VAT or with charging base at £149.99 ex VAT.
Yealink BH74 Bluetooth Headset — from £105 ex VAT

DECT vs Bluetooth — which wireless technology is better for the Yealink T4 series?
Both DECT and Bluetooth wireless headsets work with the Yealink T4 series, but they suit different situations. The right choice depends on how the phone is used and what the working environment demands.
DECT is the more reliable choice for desk phone use. DECT operates on a dedicated 1.9GHz frequency band that is separate from wi-fi and other wireless devices. In a busy office or contact centre with multiple wi-fi networks, Bluetooth devices, and other wireless equipment in operation, DECT maintains a stable connection where Bluetooth can struggle. DECT also typically offers greater range — the WH64 and WH68 both reach up to 90 metres in open space — and with an EHS adapter the user can answer and end calls directly from the headset without touching the phone.
Bluetooth suits environments where simplicity and multi-device flexibility matter more than maximum range. A Bluetooth headset connects to the T4 phone via the BT41 dongle (or built-in Bluetooth on the T44W) and can simultaneously pair with a laptop — so a user receiving a call on their desk phone and a video call on their laptop can use a single headset for both, switching between devices as needed. No EHS adapter is required. Setup is simpler. The trade-off is that Bluetooth operates on the 2.4GHz band shared with wi-fi, which can cause occasional interference in high-density wireless environments.
| Factor | DECT | Bluetooth |
|---|---|---|
| Reliability in busy offices | High — dedicated frequency, no wi-fi conflict | Good — can be affected by heavy wi-fi environments |
| Range | Up to 90m (WH64 and WH68) | Typically 10–30m |
| Remote call answer from headset | Yes — via EHS40 or EHS62 adapter | Not available on T4 series via Bluetooth |
| Connect to laptop simultaneously | Yes — WH64 and WH68 via Bluetooth to laptop while DECT to phone | Yes — Bluetooth connects to phone and laptop simultaneously |
| Setup complexity | EHS adapter required for remote call answer | BT41 dongle required on T4U models; plug and pair |
| Best for | High call volume, contact centres, moving during calls | Office professionals, T44W users, multi-device flexibility |
How do you choose the right headset for your T4 environment?
Once the connection type is confirmed, the choice narrows quickly based on how the phone is used.
| Your situation | Headset type | Recommended | From (ex VAT) |
|---|---|---|---|
| Fixed desk, high call volume | USB wired | Yealink UH37 | £59 |
| Fixed desk, noisy open-plan office | USB wired with ANC | Yealink UH48 ANC | £79 |
| T44W user, wireless without dongle | Bluetooth wireless | Yealink BH74 | £105 |
| Needs to move during calls, remote answer | DECT wireless + EHS | Yealink WH64 | £141.59 |
| Noisy environment, wireless + ANC needed | DECT + ANC wireless | Yealink WH68 ANC | £123 |

What to check before ordering a headset for your Yealink T4 phone
The most common mistake when ordering a headset for a T4 phone is not confirming the EHS adapter needed for wireless. The WH64 uses EHS40. The WH68 uses EHS62. They are not interchangeable — ordering the wrong adapter means the remote call answer function won't work even if the headset itself connects. If you are unsure which adapter your headset requires, call us on 0161 830 6818 before ordering.
The second most common issue is Bluetooth dongle compatibility. T4U models require a Yealink BT41 dongle for Bluetooth headset use — not all Bluetooth dongles are compatible. The T44W avoids this entirely with built-in Bluetooth, which is worth considering at the specification stage of a T4 deployment if Bluetooth wireless headsets are part of the plan.
Pre-order checklist:
- Confirm your exact T4 model number — T42U, T43U, T44U, T44W, T46U or T48U
- If ordering a DECT wireless headset: confirm which EHS adapter is required (EHS40 for WH64; EHS62 for WH68)
- If ordering a Bluetooth headset on a T4U model: confirm BT41 dongle is included or ordered separately
- Decide between 1-ear and 2-ear based on the working environment — contact centres typically use 2-ear for noise isolation; office professionals often prefer 1-ear to stay aware of surroundings
- For orders of 4 or more units, volume discounts apply automatically at checkout
- For larger T4 deployments, call 0161 830 6818 for a tailored quote
Try a headset on your Yealink T4 phone before committing to a deployment order
All-day comfort is the variable most buyers underestimate when specifying headsets at scale. A headset that feels fine in a five-minute trial will be assessed very differently by a contact centre agent wearing it for seven hours. Ear cushion material, headband pressure, microphone arm position, and weight all matter — and they vary significantly across models even at similar price points.
Every headset in this guide is available on a free no-obligation trial from Headsets4Business. For a T4 deployment, the recommended approach is to trial two or three models simultaneously across your most demanding users for a full working week before placing a volume order. This prevents the cost and disruption of returns across a full floor.
Volume discounts apply automatically from 4 units at checkout. For larger T4 deployments — typically 20 or more phones — call 0161 830 6818 or email sales@headsets4business.co.uk for a tailored quote that covers the full headset and EHS adapter requirement in one order.

Frequently Asked Questions
What headset works with a Yealink T46U?
The T46U has dual USB ports and an RJ9 headset port. A USB wired headset is the simplest option — plug into either USB port and it works immediately. For wireless, a DECT headset with an EHS40 adapter (or EHS62 for WH68) allows remote call answering. Bluetooth headsets connect via a BT41 dongle. The Yealink UH37 (wired) and Yealink WH64 (DECT wireless) are the most commonly specified headsets for the T46U.
What headset works with a Yealink T42U?
The T42U supports USB wired headsets, DECT wireless headsets via EHS40 or EHS62, and Bluetooth headsets via a BT41 dongle. For a contact centre environment the Yealink UH37 at £59 ex VAT is the recommended wired choice. For wireless, the Yealink WH68 ANC at £123 ex VAT (without base) offers DECT reliability with active noise cancellation — confirm the EHS62 adapter is included when ordering.
Does the Yealink T44W need a Bluetooth dongle for wireless headsets?
No — the T44W has built-in Bluetooth 4.2 and pairs directly with Bluetooth wireless headsets without any dongle. This is the main advantage of the T44W over other T4U models for users who want Bluetooth headset use. The Yealink BH74 pairs directly with the T44W at £105 ex VAT. All other T4 models require a BT41 Bluetooth dongle for Bluetooth headset use.
What is an EHS adapter and do I need one for a Yealink T4 phone?
An EHS (Electronic Hook Switch) adapter connects a DECT wireless headset base to the phone's EHS port, allowing the headset to answer and end calls remotely — without touching the phone. Without an EHS adapter, the wireless headset will still carry audio but the user must press a button on the phone to answer each call. For the Yealink T4 series, EHS40 is required for the WH64 and most compatible DECT headsets. The WH68 requires EHS62. Call 0161 830 6818 to confirm which adapter your headset requires.
What is the difference between the Yealink WH68 Teams and WH68 UC?
The WH68 Teams and WH68 UC are identical in hardware specification — both feature Hybrid ANC with Acoustic Shield 3.0, DECT and Bluetooth dual mode, 32 hours DECT talk time, 90 metre wireless range, and busylight. The difference is certification. The Teams version is optimised and certified for Microsoft Teams. The UC version is certified across multiple platforms including Teams, Zoom, Google Meet, and other UC systems — making it the more flexible choice for organisations running more than one communication platform.
What is the difference between the WH64 and WH68 for T4 series phones?
Both are DECT wireless headsets compatible with the Yealink T4 series. The WH64 uses an EHS40 adapter and does not include ANC. The WH68 uses an EHS62 adapter and includes Hybrid ANC with Acoustic Shield 3.0 — active noise cancellation on both the speaker and microphone. The WH68 is the better choice for noisy environments. The WH64 is available in 1-ear or 2-ear from £141.59 ex VAT. The WH68 starts from £123 ex VAT without a charging base.
Can I use a Jabra or EPOS headset with a Yealink T4 series phone?
Yes — Jabra and EPOS USB wired headsets connect directly to T4U and T44W USB ports. The Jabra Evolve2 30 at £74 ex VAT is confirmed compatible. For wireless, Jabra and EPOS DECT headsets connect via EHS40 with the appropriate EHS cable for your specific headset model. Call 0161 830 6818 to confirm the correct EHS cable before ordering any non-Yealink DECT headset for a T4 series phone.
Do volume discounts apply for T4 headset deployments?
Yes — volume discounts apply automatically at checkout from 4 units upward. For larger T4 deployments — 20 units or more — call 0161 830 6818 or email sales@headsets4business.co.uk for a tailored quote. We can supply a mix of wired and wireless headsets across the same order and advise on the correct EHS adapters for the full deployment.
