• Callez biggest strength: Wired USB-A reliability with dual ENC noise-cancelling mics and a built-in Teams call button plus mute — no pairing, no charging, no dropouts.
• Callez biggest trade-off: It's a cord. You're tethered to your desk by a 6.56 ft cable, and there's no Bluetooth option at all.
• LEVN biggest strength: True wireless with two connection modes — Bluetooth 5.2 or a 2.4G USB dongle — plus up to 65 hours of playback and a charging base.
• LEVN biggest trade-off: It needs power, and some call answering is done on the computer rather than on the headset — a detail worth knowing before you buy.
• For the office or call-center desk jockey who never moves: Callez USB Headset.
• For the remote worker who wants to leave the desk mid-call: LEVN Headset.
The Callez is built around one idea: make a wired headset that just works in a business environment. You plug the USB-A connector into a PC or laptop, and Windows sees it as a standard audio device — no drivers, no dongle, no pairing dance. The 28mm speakers handle stereo audio for calls and meetings, and the impedance sits at 32 ohm, which is typical for this class and easy for a laptop to drive.
The real selling point is the microphone setup. It uses dual mics with ENC — environmental noise cancellation — aimed at the exact annoyances of a home office or open-plan floor: keyboard clatter, a barking dog, kids in the next room. It won't silence a jet engine, but the design intent is clearly aimed at keeping your voice intelligible when your environment isn't quiet. The boom itself rotates 350°, so left- or right-side wear is your call, not the manufacturer's.
Then there are the controls. There's a dedicated Microsoft Teams button that can answer or end a Teams or Skype for Business call, join an active meeting, or bring Teams to the foreground. There's also volume up/down and a mic mute. One honest caveat straight from the specs: hanging up on Zoom still requires a click in the software, so the hardware button isn't a universal call-end key.
Buy it if you sit at a desk, live in Teams or Zoom, and want zero battery anxiety. Skip it if you take calls while pacing, cooking, or walking the dog — the cord will drive you mad.
LEVN Headset: Who It's For
The LEVN goes the other direction entirely. This is a wireless on-ear headset with a genuinely flexible connection story: Bluetooth 5.2 for phones and Bluetooth-equipped laptops, plus a 2.4G USB dongle for computers that don't have Bluetooth at all. Plug the dongle in, power the headset on, and the two pair automatically. The claimed wireless range is 49 ft / 15 m, which is more than enough to walk to the kitchen and back without your call cutting out.
The battery is the headline number: up to 65 hours of continuous playback on a single charge, with a 2-hour charge time. There's a charging station in the box, plus a Type-C cable — you can charge via the USB-C port or drop it on the base (the base itself needs to be connected to power). Charging status shows via LED: flashing red while charging, solid blue when full.
Noise cancellation here is described as AI-driven and active, with the manufacturer claiming it eliminates 99.9% of background noise. I'd treat that as marketing framing rather than a lab result — and the spec sheet is refreshingly honest about the limits: it picks up human voices well and kills things like children's laughter and pet barks, but low-frequency keyboard tapping and normal nearby conversation can still come through. That's a meaningful detail if you assumed "AI noise cancelling" meant total silence.
Two other things a buyer should know. First, the mic boom rotates 270°, so either-side wear works. Second, call control is limited on a computer: the multi-function button answers and hangs up on a phone, but on a computer you answer in the software. Also note the mic is not designed for desk phones or landlines.
Side-by-Side: Which Should You Choose?
• Best for zero setup and zero charging → Callez USB Headset. Wired USB-A, plug in, done.
• Best for battery life and mobility → LEVN Headset. Up to 65 hours and a 49 ft wireless range.
• Best for Teams call control → Callez USB Headset. A dedicated Teams button plus hardware mute; the LEVN routes computer call answering through the software.
• Best for connecting to non-Bluetooth computers → LEVN Headset. The included 2.4G USB dongle solves that problem directly; Bluetooth 5.2 covers the rest.
• Best for noisy open offices → Callez USB Headset. Dual ENC mics are explicitly designed around keyboard clicks, pets and kids.
• Best for quiet-ish home offices where you still want ANC → LEVN Headset. Active noise cancellation, with the honest caveat about low-frequency keyboard noise.
• Best for all-day desk comfort → either, honestly. Both use soft cushions and adjustable headbands; Callez is on-ear and light, LEVN is over-ear with enveloping cups.
• Best for warranty peace of mind → Callez USB Headset. 2 years versus 18 months.
If I had to pick one for a typical office or call-center job, I'd take the Callez USB Headset. In my opinion, the combination of wired reliability, dual ENC mics and a real Teams button is exactly what a desk-bound professional needs, and never thinking about a battery is worth more than it sounds. I'd only switch to the LEVN Headset if my day involves moving around — that's when 65 hours of battery and a 49 ft range stop being luxuries and start being the whole point. Match the tool to how you actually work, and you'll be happy either way.
FAQ
Yes. That's exactly what the included 2.4G USB dongle is for — plug it in, turn the headset on, and they pair automatically. Bluetooth 5.2 is there for phones and Bluetooth-capable laptops.
For mic clarity, I'd lean Callez — its dual ENC mics are specifically aimed at keyboard clicks, pets and kids. The LEVN's AI noise cancellation handles voices and pets well but, per its own notes, low-frequency keyboard tapping can still get through.
