If you want a workday-focused open-ear clip with hi-res codec support and a wider Bluetooth range, choose SoundPEATS PearlClip Pro; if you need marathon battery life with a visible power readout, choose kurdene Open-Ear Headphones.
• SoundPEATS PearlClip Pro — biggest strength: a pearl-style ear clip built around a flexible memory alloy core and skin-friendly silicone, plus LDAC hi-res audio and a stated 20-meter Bluetooth range.
• SoundPEATS PearlClip Pro — biggest trade-off: shorter battery (up to 6 hours per charge, 24 hours with the case) and no active noise cancellation — the open-ear design is deliberately letting the world in.
• kurdene Open-Ear Headphones — biggest strength: a 42-hour total battery figure with a digital display on the case, so you can see remaining power instead of guessing.
• kurdene Open-Ear Headphones — biggest trade-off: a 10-meter Bluetooth range and no hi-res codec mentioned, so it's the more basic connection of the two.
• Choose SoundPEATS PearlClip Pro if you work across a laptop and a phone all day and want the better-sounding, longer-range pair.
• Choose kurdene Open-Ear Headphones if battery anxiety is your main enemy and you want to glance at a number instead of a blinking light.
The PearlClip Pro is clearly pitched at people who wear earbuds as work equipment, not as a toy. The clip design uses a flexible memory alloy core wrapped in skin-friendly silicone, which is the spec that matters most here: it's what lets the earbud sit on the outside of your ear rather than jam into the canal. SoundPEATS also documents how to adjust the clip tension — pinch and pull outward if it's too tight, pinch and press inward if it's too loose — and that kind of guidance tells you the fit is meant to be tuned, not tolerated.
On the audio side, it's a 12mm dynamic driver with 32-ohm impedance, a 20 kHz frequency response, and 60 ms of latency. The tuning is described as balanced rather than bass-heavy, which is the right call for podcasts, calls and background music at a desk. The bigger differentiator is LDAC support and Bluetooth 6.0 with multi-point, so you can pair a work laptop and a personal phone at the same time and hop between them. The listed Bluetooth range is 20 meters, which is generous enough that you can walk away from your desk mid-call.
Battery is where it asks you to compromise. Up to 6 hours per charge, 24 hours total with the case, plus fast charging. That's a full workday on one charge and roughly three to four days of commuting before you need a cable — fine for most people, thin for anyone who forgets to charge.
Who should buy it: office workers, commuters, and anyone juggling two devices who wants balanced sound, LDAC, and a clip they can adjust to their own ear.
Who should skip it: if you need noise cancellation to block out an open-plan office or a loud train, this isn't that product — noise control is listed as none, because open-ear is the entire point. And if you regularly run past 6 hours of continuous listening, look elsewhere.
kurdene's take on open-ear uses an ear-hook shape rather than a clip, and it's adjustable so you can dial in the wearing position. Same core idea as the PearlClip Pro — pressure-free fit, ambient sound stays audible — but the hook form factor tends to suit people who want the earbud anchored a little more firmly during movement. The listing calls out commute, office work and outdoor travel, which lines up with the hook design.
The headline feature is battery. kurdene states 8 hours of continuous use per charge and 42 hours total with the case, and — this is the genuinely useful part — a digital power display so you can read the remaining charge at a glance. If you've ever been caught out by a pair of earbuds dying mid-call because you misread a blinking LED, that display is a small thing that changes your daily behavior. The 8-hour single-charge figure is also meaningfully longer than the PearlClip Pro's 6 hours.
Sound-wise it's a dynamic driver with 32-ohm impedance and 88 dB sensitivity, described as full and delicate with steady bass. There's no hi-res codec listed. Calls get a built-in pickup mic with noise reduction for crowded places, and the touch controls handle track skipping, volume and answering calls. Bluetooth 5.4 handles pairing and keeps audio and video in sync. Note the stated Bluetooth range is 10 meters — half the PearlClip Pro's — so this is a stay-near-your-device pair. Noise control is listed as sound isolation, though with an open-ear design that's about the seal and mic behavior, not true active cancellation.
Who should buy it: people who listen for hours at a stretch, want to see their battery level, and value a hook fit that stays put outdoors.
Who should skip it: if you want LDAC or hi-res codec support, or you like to wander far from your source device, the PearlClip Pro fits better.
• Best for battery life → kurdene Open-Ear Headphones. 8 hours per charge and 42 hours total beats 6 hours and 24 hours.

• Best for staying tethered close → kurdene Open-Ear Headphones (10 m range) vs SoundPEATS PearlClip Pro (20 m). Pick accordingly if you like to walk away from your phone.
• Best for a black, low-key look → kurdene Open-Ear Headphones. The PearlClip Pro is white, case included, which is a style call rather than a performance one.
In my opinion, the SoundPEATS PearlClip Pro is the pair I'd buy, and it comes down to how I actually use open-ear earbuds: at a desk, on calls, switching between a laptop and a phone. LDAC, multi-point Bluetooth 6.0, and a 20-meter range all serve that life better than a bigger battery number does. The 24-hour total is enough for a workweek of commuting, and 6 hours covers a full day.
That said, I'd hand the kurdene to anyone who listens for eight hours straight, wants to see their battery percentage, or needs a hook that holds firm outdoors. It's the more forgiving pair on endurance; the PearlClip Pro is the more capable pair on sound and connectivity. If battery anxiety is your biggest complaint about earbuds, the kurdene solves exactly that problem.
FAQ
No. Its noise control field is listed as none, and that's by design — open-ear earbuds let ambient sound in. The kurdene lists sound isolation, but with an open-ear structure you should still expect to hear your surroundings on both.
The PearlClip Pro supports multi-point connection over Bluetooth 6.0, so yes — that's one of its main selling points. The kurdene lists Bluetooth 5.4 for quick pairing and stable transmission but doesn't specify multi-point, so don't count on simultaneous two-device switching there.
The PearlClip Pro's clip-on design with a flexible memory alloy core and adjustable tension is the safer bet for glasses wearers, since it's built to avoid pressing on the ear. The kurdene's ear hook is adjustable too, but hooks can compete for space with glasses arms.
