Yealink WH64 Mono Wireless Single-Ear Headset DECT & Bluetooth with Base

Most wireless office headsets make you choose. DECT for your desk phone - but limited mobility and no Bluetooth for your mobile. Bluetooth for your smartphone - but no interference-free office range. You end up carrying two headsets, or accepting the limitations of one.

The Yealink WH64 Mono ends that compromise permanently.

The WH64 is the world's first wireless headset to integrate both DECT and Bluetooth technology directly into the headset itself - not into the base, not split across two separate devices. Both technologies live in the headset you put on your head. This single design decision changes everything about how you connect, how far you can roam, and how you move between your desk phone, laptop, and mobile - all while wearing the same headset, all day long.

This is the Mono version - a single-ear design that leaves one ear completely open to your physical environment. For contact centre agents who need to hear team leaders and supervisors while on customer calls. For open-plan office workers who need to stay accessible to colleagues. For reception staff who need to hear walk-in visitors. For any professional whose working day requires simultaneous awareness of both their call and their surroundings. At just 92 grams - lighter than a standard smartphone - the WH64 Mono is one of the lightest professional DECT headsets available, and one of the most comfortable for all-day contact centre and office use.

In DECT mode, the WH64 Mono delivers interference-free wireless communication with a range of up to 185 metres (607 feet), high-density deployment capability, and Secure DECT with Step C authentication that keeps every call encrypted. The dedicated DECT base connects simultaneously to your computer via USB and to your desk phone or IP phone - a single base covering both your PC softphone and your desk phone, with one-touch switching between them from the capacitive buttons on the base.

In Bluetooth mode, the WH64 Mono delivers up to 50 metres of wireless range and connects directly to your smartphone, tablet, or any Bluetooth-enabled device - without the base, without cables. Because Bluetooth lives in the headset, not the base, you can leave the base at your desk and take mobile calls anywhere in the building. Switch between DECT and Bluetooth with a single button press.

At the microphone, Yealink Acoustic Shield 2.0 technology powers three MEMS beamforming microphones with an AI-optimised noise cancellation algorithm trained across multiple professional work scenarios. The microphone boom arm is 74% longer than industry standard - 135.7mm versus the typical 78mm - positioning the microphone significantly closer to your mouth than competing headsets and fundamentally improving voice pickup quality. Beamforming focuses precisely on your voice while filtering ambient noise from all other directions - delivering clear, professional call audio in open offices, contact centres, and busy shared workspaces.

The 30mm speaker driver reproduces audio across the full 20 Hz to 20 kHz range with 6x audio equalisers for rich, natural call sound. A busylight on the earcup illuminates red the moment you are on a call - visible to colleagues, signalling your status without a word.

The DECT base is a compact, multi-functional unit - simultaneously a signal base, a charging stand, and a function button hub. It charges the headset in just 1.5 hours, provides dual USB connection for simultaneous PC and IP phone connectivity, and offers one-touch call management via its capacitive buttons.

Comfort was engineered through biometric measurements across hundreds of different head shapes. The ergonomic on-ear design uses soft memory foam cushions with a perforated breathable covering for improved ventilation and heat dissipation during long wearing sessions. At 92 grams, the WH64 Mono falls well below the typical mono wireless headset weight range of 115-170 grams - making it genuinely light enough to forget you are wearing it through a full shift.

Compatible with all major softphone and collaboration platforms - Zoom, Google Meet, Cisco Webex, RingCentral, and 100+ others. Natively compatible with Yealink IP phones and a wide range of third-party desk phones via USB or the optional EHS62 adapter. Manageable at scale through Yealink USB Connect.

DECT range. Bluetooth freedom. One ear free. All day.

KEY FEATURES

World's First DECT + Bluetooth In-Headset - The Hybrid Core AdvantageThe WH64 is the world's first headset to integrate both DECT and Bluetooth chips directly inside the headset rather than in the base. Every other DECT headset places the DECT electronics in the base - the headset is simply a receiver. Because both wireless technologies reside in the WH64 headset itself, you can use Bluetooth for smartphone calls anywhere without the base, while retaining full DECT enterprise performance whenever you are connected to it. No other DECT headset on the market offers this combination.

Situational Awareness - One Ear Always OpenThe WH64 Mono's single-ear design leaves one ear completely open to your physical environment at all times. This is the deliberate choice for professionals who need to remain aware of their surroundings while on calls. Contact centre agents who need to hear team leaders providing real-time guidance. Open-plan office workers who need to hear colleagues approaching their desk. Reception and customer-facing professionals who need to hear visitors. Drivers and field workers who need environmental awareness for safety. For all of these users, the Mono is not a compromise - it is the right tool, purpose-built for their reality.

DECT Mode - 185 Metres of Interference-Free Enterprise RangeIn DECT mode, the WH64 Mono connects to the included base for enterprise-grade wireless performance. DECT operates on a dedicated radio frequency that does not compete with the congested 2.4GHz band used by Wi-Fi, Bluetooth, and other consumer wireless devices - delivering a stable, interference-free connection in high-density office environments where Bluetooth headsets frequently drop or degrade. The WH64's DECT range of up to 185 metres (607 feet) gives you exceptional freedom of movement throughout large office floors and open-plan workspaces. Secure DECT with Step C authentication encrypts every call at the radio level.

Bluetooth 5.2 Mode - 50 Metres of Mobile FlexibilityIn Bluetooth mode, the WH64 Mono connects directly to any smartphone, tablet, or Bluetooth-enabled device within 50 metres - without the base. Leave the base at your desk and take mobile calls anywhere. When you return and place the headset on the base, it transitions back to DECT mode automatically.

One-Touch Mode Switching - DECT to Bluetooth InstantlySwitching between DECT mode and Bluetooth mode requires a single button press. Move from a desk phone call to a mobile call to a PC softphone call with minimal friction - the headset handles the connection switching without manual pairing or device navigation.

Dual-USB Base - Simultaneous PC and IP Phone ConnectionThe included DECT base connects simultaneously to both a computer and a desk phone or IP phone via its dual USB ports. Both devices are connected at all times - switch between them with one touch of the capacitive base button rather than manually re-plugging cables.

Yealink Acoustic Shield 2.0 - 3-Mic Beamforming with AI Noise CancellationThree MEMS beamforming microphones powered by Yealink Acoustic Shield 2.0 and an AI noise cancellation algorithm focus microphone sensitivity precisely on your voice while suppressing ambient noise arriving from all other directions. Clear, natural, professional voice transmission in open offices, contact centres, and environments with significant background noise.

74% Longer Microphone Boom Arm - 135.7mmThe WH64's microphone boom arm is 135.7mm - 74% longer than the industry-standard 78mm found on most wireless headsets. A longer boom arm physically positions the microphone significantly closer to your mouth, fundamentally improving voice pickup quality before the noise cancellation algorithm even engages. The boom arm is fully rotatable for comfortable positioning on either the left or right ear.

26Hr Bluetooth Talk Time / 14Hr DECT Talk TimeThe WH64 Mono delivers up to 26 hours of talk time in Bluetooth mode and up to 14 hours in DECT mode on a single charge. Music playback extends to 48 hours in Bluetooth mode. Standby time reaches 157 hours in Bluetooth mode. The 1.5-hour fast charge means a full charge fits easily within a lunch break.

1.5-Hour Fast Charging via DECT BasePlace the headset on the DECT base and it begins charging immediately - full charge in 1.5 hours. When at your desk, the headset charges automatically every time it is docked, eliminating battery management as a daily concern.

30mm Speaker with 6x Audio EqualisersA single 30mm speaker driver delivers audio across the full 20 Hz to 20 kHz frequency range with 6x audio equalisers for rich, natural call audio. Voices sound clear and present - making calls easy to follow through long contact centre shifts and busy working days.

Busylight - Visual Call Status IndicatorAn integrated busylight on the earcup illuminates red when you are on a call, providing a clear visual signal to colleagues in your workspace. In open-plan environments and shared workspaces, the busylight reduces interruptions without requiring verbal signals. The optional external BLT60 busylight is available separately for enhanced visibility in larger environments.

Featherlight at 92 Grams - All-Day ComfortAt just 92 grams, the WH64 Mono is noticeably lighter than the typical mono wireless headset range of 115-170 grams. Yealink's biometric ergonomic design combines this low weight with soft memory foam ear cushions - fitted with a thin perforated breathable cover for ventilation and heat dissipation - and an adjustable headband to create a comfortable, fatigue-free wearing experience through the longest working days and contact centre shifts.

Secure DECT with Step C AuthenticationEvery DECT call is protected by Secure DECT with Step C authentication - the highest level of DECT security, encrypting the radio communication between headset and base to prevent interception. Enterprise-grade call security for organisations that handle sensitive or confidential conversations.

FREQUENTLY ASKED QUESTIONS

Q: What is the difference between the WH64 Mono and the WH64 Dual?

A: Both versions share the same DECT + Bluetooth hybrid architecture, Acoustic Shield 2.0 three-microphone system, 185-metre DECT range, Bluetooth 5.2, and DECT base. The differences are wearing style, weight, and battery life. The Mono is a single-ear headset - 92 grams, one ear open, up to 26 hours of Bluetooth talk time and 14 hours of DECT talk time. The Dual is a stereo headset - 151 grams, both ears covered, up to 32 hours of Bluetooth talk time and 16 hours of DECT talk time. Choose Mono for situational awareness, lighter weight, and environments where one ear needs to remain open to the surroundings. Choose Dual for full immersive focus, passive noise isolation from both earcups, and stereo audio reproduction.

Q: Why would I choose a mono DECT headset for a contact centre?

A: Contact centre agents frequently need to hear both their call and their physical environment simultaneously - a team leader approaching the desk, a supervisor providing real-time coaching in the ear not on the call, an announcement over the floor PA, or a colleague passing an urgent message. A stereo headset that blocks both ears makes all of this impossible and forces the agent to constantly remove the headset. The WH64 Mono's single-ear design keeps one ear on the call and one ear on the environment - exactly the working pattern that high-performing contact centre agents use. At 92 grams, it is also light enough to wear through a full shift without fatigue, and the DECT mode provides the interference-free high-density performance that large contact centre floors require.

Q: What makes the WH64 different from other DECT wireless headsets?

A: The WH64 is the world's first wireless headset to integrate both DECT and Bluetooth technology directly inside the headset rather than in the base. Every other DECT headset places the DECT electronics in the base unit - the headset is simply a receiver for the base's signal. Because the WH64's Bluetooth chip is in the headset itself, you can use it as a standalone Bluetooth headset for smartphone calls anywhere - without the base, without cables, completely independent of your workstation. No other DECT headset offers this.

Q: Can I use the WH64 Mono as a Bluetooth headset away from my desk?

A: Yes. Because the Bluetooth chip is integrated into the headset itself, you can remove it from the base and use it anywhere as a standalone Bluetooth headset - connecting to your smartphone, tablet, or any Bluetooth-enabled device within 50 metres. Take mobile calls while away from your desk, in meeting rooms, outside the office, or anywhere else without needing to bring the base. When you return and place the headset on the base, it charges and reconnects to your PC and desk phone via DECT automatically.

Q: Why is DECT better than Bluetooth for office use?

A: DECT operates on a dedicated radio frequency that does not share spectrum with Wi-Fi, Bluetooth, microwave ovens, or other common wireless devices. In a modern office with dozens of laptops, smartphones, wireless keyboards, and other Bluetooth devices competing for the same 2.4 GHz spectrum, Bluetooth headsets frequently experience interference, audio dropouts, and connection instability. DECT's dedicated frequency is unaffected by this congestion - delivering consistent, interference-free audio quality throughout the day. DECT also supports high-density deployment, meaning many DECT headsets can operate simultaneously in the same area without degrading each other's performance. And Secure DECT with Step C authentication encrypts the radio signal at the hardware level, providing call security that Bluetooth's software-level encryption cannot match.

Q: How long is the microphone boom arm and why does it matter?

A: The WH64's microphone boom arm is 135.7mm - 74% longer than the industry-standard 78mm found on most wireless headsets. A longer boom arm physically positions the microphone much closer to your mouth, fundamentally improving voice pickup quality before the noise cancellation algorithm even engages. The microphone captures your voice with a stronger, more direct signal relative to ambient background noise - meaning the Acoustic Shield 2.0 system starts from a better acoustic position and achieves even cleaner voice transmission.

Q: How does the dual-USB base work?

A: The DECT base is equipped with two USB ports - one for connecting to your computer and one for connecting to a compatible desk phone or IP phone. Both devices are simultaneously connected at all times. One-touch switching via the capacitive button on the base moves the active audio connection between your PC and desk phone instantly. This eliminates the need to physically swap cables when switching between a PC call and a desk phone call.

Q: What is Yealink Acoustic Shield 2.0?

A: Yealink Acoustic Shield 2.0 is the second generation of Yealink's beamforming microphone noise cancellation technology. Three MEMS microphones work together using beamforming - focusing microphone sensitivity in the direction of your mouth while suppressing sounds arriving from other directions. An AI noise cancellation algorithm trained across multiple professional work scenarios processes the combined input in real time, identifying and removing background noise while preserving voice quality naturally.

Q: Is the WH64 Mono compatible with my existing desk phone?

A: Compatibility depends on your desk phone model. Yealink IP phones including T58W, T54W, T57W, T53, T44W, T34W, T43U, T46U, T48U, and MP56/58/54 connect natively via USB. Third-party desk phones including Poly VVX and certain Cisco, Grandstream, and Avaya models also connect via USB. For desk phones without a USB port, the optional EHS62 adapter provides compatibility with additional Yealink, Poly, Cisco, Snom, and Avaya models. Consult the full compatibility list or contact your Yealink reseller for your specific phone model.

Q: What is Secure DECT and why does it matter?

A: Secure DECT with Step C authentication is the highest level of security in the DECT standard. It encrypts the radio communication between the WH64 headset and base at the hardware level, preventing the wireless signal from being intercepted or decoded. For organisations handling sensitive or confidential calls - legal, financial, medical, government, or any enterprise environment - DECT's radio-level encryption provides meaningful call security that Bluetooth cannot reliably match.

Q: What warranty does the Yealink WH64 come with?

A: The Yealink WH64 is covered by a 2-year manufacturer warranty. Please confirm current terms with your retailer at time of purchase, as warranty periods may vary by region and authorised reseller.
