• Back Bay Audio ClearCall 70 — biggest strength: a removable boom mic that turns office headphones into everyday headphones in seconds, backed by a claimed 45 hours of battery life.
• Back Bay Audio ClearCall 70 — biggest trade-off: it is fully wireless with no headphone jack, so you are always dependent on a Bluetooth connection and a charged battery.
• Axtel One UC35 — biggest strength: dual noise-cancelling microphones plus a wired USB and 3.5 mm connection that works the moment you plug it in, with no pairing and no charging.
• Axtel One UC35 — biggest trade-off: the cable is the point, so you are tethered to your desk and cannot walk away mid-call.
• Who each is for: the ClearCall 70 suits people who want one pair of headphones for work and life; the One UC35 suits people who want a dedicated, always-ready desk headset.
The ClearCall 70 is built around flexibility. The boom mic is removable, which sounds like a small detail until you think about how you actually use headphones. On a work call, you attach it and you look and sound like someone on a work call. When the day ends, you pull it off and you are left with a plain pair of black over-ear Bluetooth headphones — faux leather and ABS plastic, nothing that screams "office equipment." That single design decision is the reason I would point most hybrid workers toward this one first.
The second pillar is battery. Back Bay states 45 hours of average battery life. Even if real-world use lands short of that, the shape of the number matters: it is roughly a full work week of calls plus overtime on a single charge. That changes your behavior. You stop thinking about charging as a daily chore and start treating it like a weekly one. For anyone who has had a headset die mid-presentation, that is the feature worth paying attention to.
Who should skip it? If your computer has no Bluetooth, or if you work in an environment where wireless devices are restricted, this is the wrong tool — there is no headphone jack on the ClearCall 70. And if you want a headset you never have to think about charging at all, a wired design beats it on that one narrow point. Controls are touch-based for volume, which some people love and some people fight with; that is a preference, not a flaw.
Axtel One UC35: Who It's For
The One UC35 takes the opposite approach and commits to it. This is a stereo wired headset with two connection options: USB-A and 3.5 mm. You plug it in and it works. No pairing screen, no Bluetooth menu, no battery indicator to watch. For a lot of offices — especially ones with older desktops, thin clients, or shared hot-desk setups — that reliability is worth more than any wireless convenience.
The microphone story is the headline here. Axtel uses dual noise-cancelling microphones with digital signal processing, including automatic gain control and acoustic protection. In plain terms: two mics give the system more information to separate your voice from room noise, and DSP keeps your level consistent so you do not fade in and out as you turn your head. Automatic gain control is the quiet hero of long meetings — it stops you from sounding distant when you lean back in your chair. Acoustic protection is a safety feature aimed at sudden loud spikes, which matters if you spend hours a day on calls.
Audio comes from 40 mm dynamic drivers with a 20 Hz to 20,000 Hz range. Forty millimeters is a genuinely large driver for a headset, and the range covers the full audible spectrum, so this is not a tinny voice-only device — music and video sound balanced rather than thin. The inline control module handles answer, volume, and mic mute with physical push buttons. If you have ever fumbled for a touch sensor while someone was talking over you, you know why buttons win on a work device.
Compatibility is broad by design: Microsoft Teams, Zoom, Skype, Webex, and other major apps, on PCs, laptops, tablets, and compatible communication devices. Over-ear faux leather cushions, adult sizing, and a one-year limited manufacturer warranty round out the package.
Who should skip it? Anyone who wants to stand up and walk around during calls. The cable is a leash. If your workday involves pacing, cooking, or moving between rooms while talking, the One UC35 will frustrate you — and that is exactly the gap the ClearCall 70 fills.
• Best for battery life → Back Bay Audio ClearCall 70. 45 hours stated means roughly a work week per charge; the One UC35 has no battery to run down because it draws power over the wire.
• Best for plug-and-play reliability → Axtel One UC35. USB and 3.5 mm, no pairing, no charging, no dropped connection mid-sentence.
• Best for microphone hardware → Axtel One UC35. Dual noise-cancelling mics with DSP, automatic gain control, and acoustic protection is a more elaborate voice chain than a single boom mic.
• Best for background-noise rejection while wireless → Back Bay Audio ClearCall 70. The AI noise-cancelling boom mic is aimed squarely at noisy homes and shared rooms, and it is removable when you do not need it.
• Best for listening to music after hours → Back Bay Audio ClearCall 70. Detach the mic and it becomes a normal Bluetooth headphone with a full-range dynamic driver; the One UC35 stays a desk device.
• Best for freedom to move → Back Bay Audio ClearCall 70. Bluetooth 5 with a stated 49-foot range lets you leave the desk; the One UC35's cable does not.
• Best for shared or hot-desk computers → Axtel One UC35. Wired USB and 3.5 mm connections work on machines where Bluetooth pairing is a hassle or blocked.
• Best for full-spectrum sound from a big driver → Axtel One UC35. 40 mm dynamic drivers covering 20 Hz to 20,000 Hz, versus the ClearCall 70's general-purpose 32 ohm tuning.
If I had to pick one for myself, I would buy the Back Bay Audio ClearCall 70. In my opinion, the removable boom mic plus 45 hours of battery is the combination that solves the most problems for the most people — it is a work headset during the day and a normal pair of headphones afterward, and it does not tie me to a desk. I would only switch to the Axtel One UC35 if my setup is desk-bound and Bluetooth-free, because in that scenario the dual-mic DSP chain and instant USB or 3.5 mm connection are genuinely better than anything wireless can offer. Check the current price on Amazon before you decide, since that is the one variable I cannot weigh for you here.
For most home setups, yes, in my opinion. The removable AI noise-cancelling boom mic is designed for noisy rooms, and 45 hours of battery means you are not hunting for a cable before every meeting. The One UC35 is the better pick if your computer has no Bluetooth or you prefer never charging anything.
That is the design intent. It connects over USB or a 3.5 mm jack and uses an inline module for volume, mute, and answering calls, so it is plug-and-play on PCs, laptops, tablets, and compatible communication devices. Platform support covers Microsoft Teams, Zoom, Skype, Webex, and other major apps.
The Axtel One UC35 uses two noise-cancelling microphones with DSP, automatic gain control, and acoustic protection — a more layered voice setup on paper. The Back Bay Audio ClearCall 70 counters with a single AI noise-cancelling boom mic that the maker says cuts 99% of background noise, and its boom position sits closer to your mouth, which helps in practice.
They serve different jobs, so owning both is a reasonable setup: keep the wired One UC35 at the desk for long meeting days and use the ClearCall 70 when you want to move around or listen to music with the boom mic detached. Neither replaces the other entirely, which is why the choice really comes down to how you work.
