Yealink WH66 vs. Yealink HA64 Pro

A Real-World Comparison - And Which One Makes More Sense for You

If you’ve been researching business headsets lately, you already know the problem:

1. There are a lot of options to choose from.
2. Many look similar which only further complicates the decision making process.
3. Many claim to be premium, but many find themselves disappointed after their purchase.

Two models that often get compared when buyers are looking for a professiional headset are the Yealink WH66 and the Yealink HA64 Pro. On paper, these two Yealink headsets seem close. But when you break them down by how people actually use them, the differences become much clearer.

In this blog, I’ll walk through how these two headsets compare in real-world use, broken down by specific categories, and explain why each difference matters to you as the user.

And if you’d rather see them side-by-side visually, you can watch our full YouTube comparison below.

First, The Big Picture

The WH66 is built primarily as a powerful office desk headset. The DECT technology offers wider than Bluetooth range, secure connection, 4 inch touchscreen, integrated speakerphone, optional wireless charger, and USB hub. For those who want a lightweight, full-featured DECT wireless headset, the WH66 is a solid choice to consider.

The HA64 Pro is designed to be a hybrid-flexible headset - something that works in the office and outside of it. One commanding differentiator is its dual frequency. Unlike other headsets, the Yealink HA64 Pro comes standard with DECT, and Bluetooth. And though other headsets may make this same claim, the HA64 Pro houses the Bluetooth from within the headset vs. from within the base. That distinction allows the HA64 Pro to be used in, or out of the office seamlessly. Something other headsets can't match.

Having DECT + Bluetooth in the HA64 Pro makes it a more flexible headset solution for those who are looking for a professional grade headset that can be used with all their devices.

Connectivity & Simultaneous Device Connections

When reviewing professional headsets, one thing you’ll be considering is:
What many devices can the headset be used with, and how many of these devices can be connected simultaneously.

This has emerged over time as one of the key considerations in headset procurements because modern professionals rarely use just one device. Today’s work environment typically requires toggling between different devices such as computers, desk phones and mobile devices.

Side-by-Side Comparison

WH66

Connects to 2 devices simultaneously
Designed primarily for desk-based setups

HA64 Pro

Connects to 3 devices simultaneously
Built with DECT + Bluetooth

Why This Matters

If you’re working at a desk with:

A computer
And a desk phone

The WH66 handles that beautifully. But today, many users also need:

A mobile phone connected
Or the ability to leave the office while staying connected

The HA64 Pro’s DECT + Bluetooth combination means:

DECT for stable office connectivity and long wireless range (DECT outperforms Bluetooth by a wide margin)
Bluetooth for mobile flexibility
Three active device connections making it seamless to switch between them

That flexibility becomes a major advantage in hybrid environments.

If you move between office and remote work, the HA64 Pro simply adapts better, and represents the far better solution if comparing these two models.

Microphone System & Call Quality

Microphone performance is one of those areas where spec sheets don’t always tell the whole story, but it absolutely affects daily experience. In our surveys, and decades of experience, audio quality remains top of the list of what headset buyers are looking for. With that in mind, it’s easy to understand why voice quality, and noise reduction are key decision making features.

Side-by-Side Comparison

WH66

Professional-grade office microphone
Designed for structured work environments

HA64 Pro

Enhanced microphone system
Engineered for stronger noise isolation and clearer voice pickup

Why This Matters

If you’re in a quiet office, both will perform very well with either model being a prudent choice.

But if you:

Work around background noises (coworkers, children, pets etc)
Take calls in varied environments
Move between office and remote settings

The HA64 Pro’s upgraded microphone system, and seamless connectivity offers an edge.

Clearer voice pickup = fewer “Can you repeat that?” moments.
That means more professional calls and less communication fatigue. Your callers will hear you loud, clear and consistent, even when there’s a lot going on around you. The WH66 also handles noise well, and has a professional grade microphone, but the HA64 has the edge due to more updated microphone technology.

Battery Life

Battery life isn’t just about how many hours are listed on a spec sheet. It’s about whether the headset keeps up with your day. And for many, that day can be long, and demanding. Whether it’s made up of marathon voice calls, long video meetings, or a combination of both, it’s important to have a headset with enough battery strength to carry you through the day, without any battery anxiety issues.

Side-by-Side Comparison

WH66

Strong all-day battery performance - up to 13 hours of talk time
Designed for structured office shifts

HA64 Pro

Extended battery performance - up to 16 hours of battery life
Built for power users and mobile flexibility

Why This Is Important

For someone working predictable desk hours, the WH66 has plenty of battery to carry you through the day, and for some, even into the next.

But if your day includes:

Long meetings
Stepping away from your desk
Working from multiple locations
Extended call sessions

The HA64 Pro’s extended battery performance gives you a bit more breathing room.

More battery = less charging anxiety.
Less charging anxiety = fewer interruptions.

Fewer interruptions = being more productive

Office-Only vs. Hybrid Freedom

If you work mostly in an office, the Yealink WH66 is a great headset to consider. It's DECT technology provides more than enough wireless range for most people, and DECT offers a high level of call security.

The HA64 Pro, however, is built using DECT + Bluetooth, which means it's different when compared to the WH66 model, which is a DECT headset.

That means:

Office use via DECT
Mobile phone pairing via Bluetooth
Use outside the office without losing functionality

So if your work life is flexible, the HA64 Pro was designed with you in mind. This distinction alone should help anyone to more easily decide between these two professional headsets.

That depends entirely on your work style.

The WH66 Is Ideal If You:

Need dual-device connectivity
Want a strong, office-focused communication hub

The HA64 Pro Is Ideal If You:

Microphones and sound quality
Noise canceling features and capabilities
Wireless technology
Simultaneous connections (between computer, desk phone, mobile)
Battery life
