How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a phone-free, waterproof training partner you can wear in the pool and on the trail, choose DEMICEA Open Ear Sport; if you need a work headset that keeps your voice clear on push-to-talk calls all shift long, choose Jabra Perform 45.
• DEMICEA Open Ear Sport — biggest strength: Open-ear bone conduction design with 32 GB of built-in storage, so you can carry thousands of songs and swim or run without your phone. IP68 sealing backs that up for sweat, rain and pool water.
• DEMICEA Open Ear Sport — biggest trade-off: No active noise cancellation (noise control is listed as "None"), and bone conduction audio will never isolate you from your surroundings the way an in-ear headset does.
• Jabra Perform 45 — biggest strength: A mono push-to-talk headset built for retail and team comms, with a noise-cancelling microphone and Face2Face mode for talking to customers face to face.
• Jabra Perform 45 — biggest trade-off: It's a work tool, not a music device — one earbud, passive noise cancellation only, and no built-in music storage.
• Choose DEMICEA Open Ear Sport if you're a swimmer, runner or gym-goer who wants music without a phone.
• Choose Jabra Perform 45 if you work a floor shift and need to talk to your team and to customers through the same headset.
The DEMICEA Open Ear Sport is a bone conduction headphone built around one idea: keep your ears open, keep your phone in the locker. It uses an open-ear hook design with a 0.7 mm flexible memory titanium-alloy frame and a skin-friendly silicone rear bridge, and the whole thing weighs just 26 g (0.99 oz). That combination matters if you wear sunglasses while you run — the balanced weight distribution is designed so the band and your shades don't fight each other. The soft silicone cushions sit on the front of the ear rather than inside it, which is the whole point of bone conduction: nothing blocks your ear canal, so sweat doesn't pool and you stay aware of traffic, other runners and your surroundings.
Who should buy it: swimmers, open-water and pool lap swimmers especially, plus runners and gym users who want their ears free and their music local. Who should skip it: anyone who wants noise cancellation, deep bass isolation, or a headset for phone calls in a loud workplace. This is a sport device, not an office device. The IP68 rating is the headline durability claim — it's sealed and nano-coated against sweat, rain and swimming — and it's backed by an 18-month warranty per the item details.
Jabra Perform 45: Who It's For
The Jabra Perform 45 is a different animal entirely. This is a mono Bluetooth headset — one earbud, worn on either ear — designed for push-to-talk communication in retail and team environments. Its defining feature is the dedicated PTT button, which works out of the box with the Walkie Talkie app in Microsoft Teams, Zello, and Zebra Workcloud Sync. If your job already runs on one of those, this headset slots straight into your workflow instead of forcing you to hold a phone.
The second pillar is the microphone. Jabra rates the noise-cancelling mic as removing up to 93% of background noise while optimizing your voice — the kind of thing that matters when you're calling across a shop floor, a stockroom or a busy back-of-house. The 10 mm speaker is tuned for speech clarity rather than music. Face2Face mode is a genuinely clever touch for customer-facing work: lift the boom to mute incoming audio so you can talk to the person in front of you, lower it to jump back into team comms. No fumbling with buttons mid-conversation.
Battery is rated at up to 11 hours of talk time, 20 hours of push-to-talk time, and 9 days of standby on a 2-hour charge — a full shift plus change, which is exactly what a work headset needs to deliver. It's IP54-rated for dust and splash resistance, which covers retail environments but not swimming. It weighs about 20 g, ships with three sizes of EarGels (medium fitted by default) and a USB-C cable, and includes a 1-year warranty. Bluetooth 5.3 keeps the wireless side current.
Side-by-Side: Which Should You Choose?
• Best for swimming and water workouts → DEMICEA Open Ear Sport. IP68 versus IP54 is the decisive gap here; only one of these is built for the pool.
• Best for phone-free music → DEMICEA Open Ear Sport. 32 GB of onboard storage and 4,000-plus songs means no phone required.
• Best for battery endurance during work → Jabra Perform 45. Up to 11 hours of talk time and 20 hours of PTT time versus 8 hours of music playback.
• Best for clear calls in noisy places → Jabra Perform 45. The noise-cancelling mic is the single biggest functional difference between these two.
• Best for team communication → Jabra Perform 45. Native PTT support for Teams, Zello and Zebra is core to its design; DEMICEA lists no such integration.
• Best for open-ear awareness while running → DEMICEA Open Ear Sport. Bone conduction keeps your ear canal clear, and the titanium-alloy frame is built to coexist with sunglasses.
• Best for all-day comfort on a single ear → Jabra Perform 45. At roughly 20 g with three EarGel sizes and either-ear wear, it's tuned for long shifts.
• Best fit for a music-first athlete → DEMICEA Open Ear Sport. Bone conduction driver, 20 Hz–20 kHz range, AAC/SBC — it's a listening device first.
• Best fit for a customer-facing job → Jabra Perform 45. Face2Face mode exists specifically for the moment a customer walks up to you.
If I had to pick one, I'd buy the DEMICEA Open Ear Sport — but only because my use case is training, not work. In my opinion, the combination of IP68, 32 GB of built-in storage and bone conduction is hard to argue with for swimmers and outdoor runners; it solves problems a regular headset can't. That said, if you're buying for a job — retail, warehouse, team comms — I'd take the Jabra Perform 45 without hesitation. The noise-cancelling mic, PTT support and 11-hour talk time are exactly what a work headset should be. These two barely compete; they just happen to share a Bluetooth spec sheet. Pick the job, then pick the headset.
Yes — that's its defining feature. It carries an IP68 waterproof rating with a sealed design and nano-hydrophobic coating, plus 32 GB of built-in storage so you can swim without carrying a phone. Battery is rated up to 8 hours on a 2-hour charge.
It can connect as a standard Bluetooth headset, but it's a mono earbud tuned for voice, with a 10 mm speaker and passive noise cancellation only. For music-first listening, the DEMICEA is the better fit.
By the numbers, the Jabra Perform 45: up to 11 hours of talk time and 20 hours of push-to-talk time, versus 8 hours of music playback on the DEMICEA. Both charge in about 2 hours.
The Jabra Perform 45. Its noise-cancelling microphone is rated to remove up to 93% of background noise. The DEMICEA lists no noise control at all, which is typical for bone conduction sport headphones.
