• SproutingSound Open Ear — biggest strength: Wireless Bluetooth 5.4 freedom with an open-ear design that leaves your ears uncovered, so you stay aware of traffic and surroundings during runs, rides, and drives.
• SproutingSound Open Ear — biggest trade-off: It's a single wireless earpiece-style headset with a 100mAh battery, so you're managing charge cycles and you'll want the magnetic charging cable on hand.
• Callez USB Headset — biggest strength: Dual-mic ENC noise cancelling with a dedicated Teams call button and mic mute, powered straight off a USB-A port with no battery to think about.
• Callez USB Headset — biggest trade-off: It's wired and computer-tethered with a 6.56ft cable, so it's tied to your desk or laptop rather than your ears on the move.
• Who each pick is for: SproutingSound for active, mobile listeners who need awareness and wireless convenience; Callez for desk-bound talkers who live in meetings and need clean voice pickup.
The SproutingSound Open Ear is built around one idea: keep your ears open. Instead of sealing off your ear canal or clamping over your ears, it sits in an open-ear position using a soft silicone or soft-plastic enclosure. That matters most when you're outside. On a run, a bike ride, a hike, or behind the wheel, you can still hear cars, other people, and ambient cues while your audio plays. That awareness is the entire point of the design, and it's why open-ear sets have become popular with cyclists and runners who don't want to be cut off from the world.
On the tech side, it runs Bluetooth 5.4 with a 10-meter range, which means a faster, more stable wireless link and lower power draw than older Bluetooth versions. The driver is a 15.4mm dynamic diaphragm with a 20Hz–20,000Hz frequency range and 16-ohm impedance, which is the kind of spec that points to full-range sound with bass presence rather than thin, tinny output. Battery life is rated up to 12 hours from a 100mAh lithium-ion cell, with a 1.5-hour charge time via the magnetic charging cable. Controls are touch-based for volume and calls, and the ENC microphone suppresses up to 90% of ambient noise while preserving your voice, plus there's a mute button that silences you without cutting off the other party.
Who should buy it: commuters, runners, cyclists, drivers, and anyone who wants one lightweight wireless headset for music and calls without blocking their ears. Who should skip it: if you work at a desk taking back-to-back calls all day in a noisy office, the open-ear form and single wireless design won't isolate your voice the way a dedicated wired call headset will.
The Callez USB Headset takes the opposite approach. It's a wired, on-ear headset that plugs into a computer with a USB-A connector, so there's no pairing, no charging, and no battery anxiety — it draws its power from the port. The enclosure is leather, the earcups are circular and sit on your ears, and the whole thing weighs just 2 oz. with an adjustable headband and soft memory foam, which is clearly aimed at all-day wear.
The headline feature is the dual-mic ENC noise cancelling system. There's a main mic and a separate noise-reduction mic, and the built-in noise-cancelling chip runs what Callez calls A8 algorithm technology to pull your voice out of background chatter. That's a call-quality play, not a music play. The inline controls cover mic mute, volume, and a dedicated Teams call button: one press answers, ends, or cancels a Teams call, and it can also open Teams or join a meeting. It works with Skype for Business built on Teams too. For Zoom, the button answers calls, but you hang up from the software. There's also a visual busylight so people around you know you're on a call.
Who should buy it: office workers, remote employees, call center agents, students in online classes, and anyone who spends the day in Teams or Zoom and wants a dependable wired connection with strong voice pickup. The 6.56ft cable gives you room to move at your desk. Who should skip it: if you want to listen while walking, driving, or working out, the wired, computer-only design simply isn't the tool — it lives plugged into your laptop.

• Best for all-day desk calls → Callez USB Headset. Wired USB power, dual-mic ENC, and a Teams button make it a meeting machine with no charging to manage.
• Best for wireless freedom → SproutingSound Open Ear. Bluetooth 5.4 with a 10-meter range means no cable tying you to a port.

• Best for battery life → SproutingSound Open Ear. Up to 12 hours per charge from a 100mAh cell, though it's the one you have to remember to charge.

• Best for music detail → SproutingSound Open Ear. The 15.4mm dynamic driver and 20Hz–20,000Hz range point to a fuller listening experience than a call-first headset.
• Best for plug-and-play simplicity → Callez USB Headset. No pairing, no charging — plug into USB-A and go.
My Verdict
For pure call quality at a desk, the Callez USB Headset has the edge thanks to its dual-mic ENC system, dedicated Teams call button, and mic mute. The SproutingSound handles calls too, with ENC and a mute button, but its open-ear wireless design is better suited to mobile use than to being your daily meeting headset.
No. The Callez is a wired USB-A headset built for computers, with a fixed 6.56ft cable, so it's tethered to a laptop or desktop. If you want something for running, cycling, or driving, the SproutingSound Open Ear is the one that fits, since it's wireless Bluetooth 5.4 with an open-ear design.
It's rated for up to 12 hours of playtime from a built-in 100mAh lithium-ion battery, with a full charge taking about 1.5 hours. It charges through a magnetic charging cable, so keep that cable somewhere you won't lose it — replacements are sold separately.
Both are different tools at different price points, and I can't quote numbers here. Since the SproutingSound is a wireless Bluetooth headset and the Callez is a wired USB unit, the fairest move is to check the current price on Amazon for each and compare them against your actual use case.
