• Avantree Alto Clair — biggest strength: Bluetooth 5.0 with aptX HD and aptX Low Latency, a detachable boom mic, a mute button on the mic, and a desktop charging base — a wireless work-and-listening setup in one box.
• Avantree Alto Clair — biggest trade-off: It needs charging, the built-in mic and controls stop working in wired mode, and the on-ear fit is lighter but less enclosing than an over-ear design.
• Sonitum Headset — biggest strength: Wired 3.5 mm connectivity that works instantly with almost anything, an over-ear design built for hours of wear, and a fully rotatable mic that swings up out of the way.
• Sonitum Headset — biggest trade-off: It's tethered to a cable, and the headset's own noise control is passive-style while the active noise cancellation applies to the mic — so it won't silence a loud room for your ears.
• Who each pick is for: Avantree Alto Clair for people who want wireless freedom plus music in the same headset; Sonitum Headset for people who live on calls and want zero setup.
The Alto Clair is a Bluetooth 5.0 on-ear headset built around flexibility. You get Hi-Fi stereo sound with aptX, plus aptX Low Latency to cut the lag that usually plagues wireless audio. In practice that matters most for voice and video: the spec sheet puts aptX Low Latency delay at roughly 32–40 ms, which is below what the human ear picks up as lip-sync error. Pair it with low-latency gear and calls, meetings and streamed video stay in sync instead of drifting.
The part I like most for office work is the detachable boom microphone. It's a real boom, not a pinhole array buried in the earcup, and it has its own mute button right on the mic for fast silencing mid-call. There's also a separate call button that wakes Siri or Google Assistant, so you're not fumbling through menus to answer. At 155 g with soft protein earpads and an adjustable headband, it's light enough to forget you're wearing it, and the included charging base doubles as a desk stand — you drop it on the base and it's topped up for the next call. The box also includes a 3.5 mm AUX cable for wired listening.
Sonitum Headset: Who It's For
The Sonitum is the opposite philosophy: wired, simple, and aimed squarely at talk. It connects over a 3.5 mm jack, so there's no pairing, no charging, no dongle — you plug it into a laptop, a phone or a desk phone with the right port and you're on a call. For an office that runs on Teams, Zoom or Skype all day, that instant-on reliability is the whole point.
Two design choices stand out. First, it's an over-ear headset, which spreads pressure around the ear rather than pressing on it, and the spec sheet says the aim is comfort even after hours of use. If your calendar is wall-to-wall meetings, that's the difference between taking the headset off at lunch and forgetting it's there. Second, the microphone fully rotates. You can position it for your face shape, and when you're not on a call you flip it up and out of your line of sight. The mic itself uses noise-reduction technology to strip out background sound so the people on the other end hear your voice, not the office.
The trade-off is honest and worth stating: this is a wired headset. You're attached to your desk, your cable length and your port. The noise control listed is active noise cancellation, but read that in context — the noise-cancelling story here is about cleaning up your outgoing mic audio, not about blocking the room out of your ears. There's no Bluetooth, no charging base, no music-first tuning. It's a call tool.
Who should buy it: call-center staff, remote workers on constant video meetings, students in online classes, and anyone who wants a headset that simply works the moment it's plugged in. Who should skip it: if you want to walk to the kitchen mid-call, or you want the same headset for wireless music and low-latency video, the cable will get old fast.
• Best for wireless freedom → Avantree Alto Clair. Bluetooth 5.0 means you can take a call away from your desk; the Sonitum is tethered by its 3.5 mm cable.
• Best for zero-setup calls → Sonitum Headset. Plug in and talk. No pairing, no charging, no battery anxiety before a client call.
• Best for music and video too → Avantree Alto Clair. aptX HD and aptX Low Latency make it a genuine all-rounder, not just a voice headset.
• Best for long meeting marathons → Sonitum Headset. The over-ear design is built for hours of wear, where the Alto Clair's on-ear pads rest against the ear.
• Best for quick muting mid-call → Avantree Alto Clair. The mute button sits on the boom mic itself, so it's a one-touch move.
• Best for storing the mic out of sight → Sonitum Headset. The rotating mic flips up and disappears when you're not talking.
• Best for a tidy desk → Avantree Alto Clair. The charging base holds and recharges the headset between calls.
• Best for device compatibility → Sonitum Headset. A 3.5 mm jack fits laptops, phones and tablets with no adapter fuss; the Alto Clair's wireless range is affected by walls and doors.
• Best for outgoing voice clarity in a busy room → Sonitum Headset. Its noise-reduction mic is explicitly designed to cut background sound on your end.
In my opinion, the Avantree Alto Clair is the better buy for most office workers. It covers more ground: wireless calling, low-latency video, aptX HD music, a mute button on the boom, and a charging base that keeps it ready on your desk. You pay for that versatility with battery management and a lighter on-ear fit.
If your day is nothing but calls and you want a headset that never asks anything of you, I'd point you to the Sonitum Headset instead — the wired connection and over-ear comfort are exactly right for that job. But as a single headset for a modern hybrid workday, I'd take the Alto Clair.
what are the best headphones for office calls
For pure call work, the Sonitum Headset is the straightforward pick thanks to its wired 3.5 mm connection, rotating noise-reducing mic and over-ear comfort. If you also want wireless freedom and music playback, the Avantree Alto Clair with its detachable boom mic and charging base covers more of the day.
what are the best headphones for the office
It depends on how you work. The Alto Clair suits a desk where you move around and mix calls with music, since Bluetooth 5.0 and aptX Low Latency handle both. The Sonitum suits a fixed desk with nonstop meetings, where plug-and-play and long-wear comfort matter more than wireless.
can you wear headphones in the office
Yes, and both of these are designed for it — but check your workplace's policy first. The Alto Clair is a light 155 g on-ear model with soft protein earpads, while the Sonitum is an over-ear headset built for hours of wear. Either way, a boom or rotating mic makes it obvious you're on a call.
which headphones are best for office calls
If your calls happen at your desk and you never want to think about charging, the Sonitum Headset's wired design and rotatable mic are the simplest answer. If you want to walk away from your desk mid-call and use the same headset for music and video, the Avantree Alto Clair is the stronger fit.
