• Zoom ZHA-4's biggest strength: It turns a single stereo output into four powered 3.5 mm jacks, each with its own volume knob and its own mute button — something no ordinary headphone splitter can do.
• Zoom ZHA-4's biggest trade-off: It's a wired, passive-source device. It amplifies what you feed it, so you still need a source and your own headphones, and it won't work as a standalone wireless headset.
• Yealink WH64's biggest strength: DECT plus Bluetooth dual-mode connectivity that links three devices at once, with a claimed 606 ft DECT range and up to 26 hours of mono talk time.
• Yealink WH64's biggest trade-off: It's a single-user headset. Only one person hears the audio, and it's on-ear mono, so it's not built for shared critical listening.
• Who the Zoom ZHA-4 is for: Podcasters, bands, producers and small production crews who need several people monitoring the same mix with individual control.
• Who the Yealink WH64 is for: Office workers, call center agents and hybrid professionals who want one headset roaming between PC, IP phone and mobile.
The Zoom ZHA-4 is a portable, battery-powered stereo headphone amplifier built for demanding, critical audio monitoring. The pitch is simple: you feed it one stereo signal through the included 3.5 mm mini cable, and it splits that signal into four independent powered headphone outputs. Every one of those four jacks has a dedicated volume knob and its own mute button, so channel two can go silent while channel one keeps working — without touching the master settings. That last detail is the whole reason this box exists. A cheap passive splitter gives everyone the same level and no way to isolate anyone; the ZHA-4 gives each listener their own control.
Who should buy it? Anyone running a session where multiple people need to hear the same source at the same time with their own level control: a podcast with a host and guests, a band tracking together, a production crew monitoring a feed, or a small video shoot. It's also a neat little problem-solver if you want to share one laptop's output with several wired headsets. Who should skip it? If you want a wireless headset for taking calls, this isn't that — it has no mic, no wireless link, and no software ecosystem. It's a monitoring tool, nothing more.
Yealink WH64: Who It's For
The Yealink WH64 is a wireless mono headset aimed squarely at people who spend their day on calls. It runs DECT and Bluetooth together, and it can connect three devices at the same time — a PC, an IP phone and a mobile — so you can switch between them without re-pairing anything. The DECT side is the headline: Yealink rates it at 606 ft of range with strong anti-interference and secure call encryption. That's the difference between pacing your office during a call and being glued to your desk.
Audio is handled by a 3x noise-canceling mic paired with Acoustic Shield Tech 2.0, which in plain terms means the headset tries to build a quiet zone around your voice when you're in a noisy room. You get call control on the headset itself, a busylight so coworkers know you're on a call, a ringtone, and two ways to mute quickly — press the button or lift the boom arm. The specs list 32 mm dynamic drivers covering 20 Hz to 20,000 Hz at 32 ohm impedance, with passive noise cancellation from the on-ear fit.
Battery life is the part that stands out. Yealink claims 26 hours of mono talk time and 41 hours of mono music playback, with 157 hours of mono standby, and a full charge in just 1.5 hours. Comfort gets real attention too: nano breathable memory foam with hydrolysis-resistant leather, an adjustable headband, and earcups that rotate up to 90 degrees each way with balanced clamping force. The package includes the WHB640 base, a USB-C to USB-A cable, a Micro USB to USB-A cable, an adapter, a drawstring bag and a user manual, plus a two-year technical support commitment.
Who should buy it? Office workers, call center agents and hybrid staff who want one headset covering desk phone, softphone and mobile, and who value range and battery over everything. Who should skip it? Anyone who needs multiple people hearing the same audio, anyone who wants stereo music listening from a headset, and anyone who prefers a wired, latency-free monitoring chain. Note that some desk phone models need an EHS62 or telephone cable sold separately, so check your phone against Yealink's compatibility list before buying.
• Best for shared monitoring → Zoom ZHA-4. Four independent outputs with individual volume and mute is a category of its own.
• Best for range and roaming → Yealink WH64. DECT at 606 ft with secure encryption beats any wired setup for moving around.
• Best for battery life → Yealink WH64. Up to 26 hours of mono calls and 157 hours of mono standby, versus AA batteries that you'll swap.
• Best for multi-device switching → Yealink WH64. Three devices connected simultaneously across DECT and Bluetooth.
• Best for podcast or band sessions → Zoom ZHA-4. Feed one mix to four listeners and let each person set their own level.
• Best for call clarity in a noisy room → Yealink WH64. The 3x noise-canceling mic and Acoustic Shield Tech 2.0 are built for exactly that.
• Best for a simple, no-software desk setup → Zoom ZHA-4. Plug in the mini cable, add headphones, done.
• Best for a headset you'll wear all day → Yealink WH64. Memory foam, rotatable earcups and balanced clamping force are designed for long wear.
In my opinion, these two don't compete — they cover opposite halves of the audio world. For a laptop setup where several people need to hear the same thing, I'd buy the Zoom ZHA-4 without hesitation; the four independent volume and mute controls are something no splitter replicates. For a laptop setup where one person takes calls all day and wants to walk away from the desk, I'd buy the Yealink WH64. If you're the typical hybrid worker juggling a PC, a desk phone and a mobile, the WH64 is the one that earns its place on your head. If you're running sessions, the ZHA-4 is the one that earns its place in your bag. Check the current price on Amazon for whichever fits, since both sit in very different budget brackets.
It depends entirely on the job. For sharing one laptop's audio with several wired headsets for monitoring, the Zoom ZHA-4 is the right tool. For taking calls on a laptop with wireless freedom, the Yealink WH64 is the right tool.
No. It's a battery-powered headphone amplifier, not a headset. It has no microphone and no wireless link — it only splits and amplifies a wired stereo signal into four 3.5 mm outputs.
No. It's a single-user mono on-ear headset. Only the wearer hears the audio through the 32 mm drivers, so it isn't suitable for shared monitoring.
The Yealink WH64 clearly lasts longer per charge, with up to 26 hours of mono talk time and 157 hours of mono standby, and a 1.5-hour charge time. The Zoom ZHA-4 runs on two AA batteries or USB-C power, which is flexible but means replacing or recharging batteries.
Possibly. Some desk phones connect via USB cable directly, but others need an EHS62 or telephone cable sold separately, so check Yealink's compatibility list for your specific phone model before ordering.
