If you want a wireless, dock-charging headset you can wear all day across laptop, phone and tablet, choose Delton 50X; if you need a wired USB headset with a dedicated Microsoft Teams button and dual-mic noise cancelling for desk-based calling, choose Callez Computer Headset.
• Delton 50X — biggest strength: Wireless Bluetooth 5.0 freedom with 35 hours of talk time, 40 hours of playtime, and a charging dock plus USB dongle, so you're not tethered to a desk.
• Delton 50X — biggest trade-off: It's a monaural (single-ear) over-ear design, so it isn't built for immersive stereo listening, and every function lives on the headset itself rather than a desk control unit.
• Callez Computer Headset — biggest strength: Dual ENC microphones, a 350-degree rotating boom, a one-touch Microsoft Teams call button, and a busylight — a purpose-built calling tool.
• Callez Computer Headset — biggest trade-off: It's wired via USB-A, so you're limited by a 6.56 ft cable, and it only works with devices that accept a USB-A connection.
• Who each pick is for: Delton 50X → mobile professionals who jump between devices and hate recharging. Callez Computer Headset → desk-bound call center, office and home-office users who live inside Microsoft Teams.
The Delton 50X is built around one idea: keep you talking without plugging in. It pairs over Bluetooth 5.0 with a 10-meter range, so you can walk to the kitchen mid-call and stay connected. The battery figures are the headline — 35 hours of talk time and 40 hours of playtime from a 2-hour charge. In my reading of those numbers, that's roughly a full workweek of meetings on a single charge, which is the kind of headroom that matters if you're the person who always forgets to plug in.
Audio-wise, it uses DSP and ENC to suppress background noise and lift your voice, with a 30 mm dynamic driver covering 20 Hz to 20,000 Hz. That's a full-range driver, which is why it doubles as a music and podcast headset on top of its call duties. The microphone rotates 270 degrees so you can park it where it picks you up best, and the adjustable headband plus soft head cushion and plush ear cushions are aimed at long wear. It's a monaural over-ear design, so one ear stays open to your room — good for awareness, less good if you want to block out an open office.
Buy it if you move between a Windows PC, a Mac, a phone, a tablet or even a desktop phone and want one headset that follows you. The included USB dongle and charging dock mean you can leave the dock on your desk and just drop the headset in. Skip it if your whole job is anchored to one desk and you'd rather have a wired connection you never think about, or if you want true stereo sound for focused listening.
The Callez Computer Headset takes the opposite approach: it stays put and does one job extremely well. It's a wired USB-A headset with dual ENC microphones and a flexible boom that rotates 350 degrees, so you can fine-tune mic placement for a busy room. The 28 mm speakers are tuned for voice rather than music, and Acoustic Shock Protection is there to guard your hearing against sudden loud spikes — a detail that matters if you take calls all day in a call center or shared office.
The standout feature is the Microsoft Teams call button. One press opens the Teams window or joins a meeting, and you also get volume up/down and mic mute on the headset itself. The visual busylight is a small thing that changes your day: colleagues can see you're on a call and leave you alone. Weight is about 3 oz, with soft memory foam, skin-friendly material and an adjustable headband, plus a 6.56 ft cable that lets you lean back or reach across the desk.
Buy it if your work runs through Microsoft Teams on a laptop or desktop and you want a headset that's ready the second you sit down — no pairing, no charging, no battery anxiety. The brand backs it with a 45-day money-back window and a 24-month warranty. Skip it if you need to roam, take calls on your phone, or want a headset that also handles music and podcasts well; the wired USB-A connection and voice-tuned drivers make it a specialist, not an all-rounder.

• Best for battery life → Delton 50X. 35 hours talk time and 40 hours playtime, recharged in about 2 hours via cable or dock.

• Best for all-day comfort at a desk → Callez Computer Headset. Around 3 oz with memory foam and a lightweight on-ear fit.

• Best for plug-and-play simplicity → Callez Computer Headset. USB-A in, no pairing or charging to think about.
If I had to pick one, I'd buy the Callez Computer Headset for a desk-based job that runs on Microsoft Teams. In my opinion, the Teams call button, dual ENC mics, busylight and 2-year warranty make it the more focused tool for someone who takes back-to-back calls at a computer, and the wired connection removes battery anxiety entirely.
That said, I'd choose the Delton 50X without hesitation if your work follows you — between devices, around the house, or onto your phone. The 35-hour talk time, charging dock and Bluetooth range simply do things the Callez can't. Match the headset to how you actually work, and either one will serve you well. As always, check the current price on Amazon before you commit.
The Callez Computer Headset has a dedicated Teams call button that opens the Teams window or joins meetings with one press. The Delton 50X is compatible with Teams and other apps over Bluetooth, but you control calls from the headset buttons rather than a Teams-specific key.
No. It's a wired USB-A headset with a 6.56 ft cable, so it needs a USB-A port on your computer. If you need wireless freedom, the Delton 50X with Bluetooth 5.0 and a USB dongle is the better fit.
Both address noise, but differently. The Callez uses dual ENC microphones and a 350-degree rotating boom for voice pickup. The Delton 50X uses DSP and ENC with a 270-degree rotating mic. For a fixed desk in a loud room, I'd lean Callez; for calls on the move, Delton.
The Delton 50X offers 35 hours of talk time and 40 hours of playtime, charging in about 2 hours via cable or dock. The Callez is wired, so it has no battery to run down — it draws power from the USB connection.
