How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a headset built for swimming and music without your phone, choose Sanag B33S; if you need a lightweight push-to-talk work headset for retail or team comms, choose Jabra Perform 45.
• Sanag B33S — biggest strength: IPX8 waterproofing plus 32GB of built-in MP3 storage, so you can swim and train with music and no phone nearby.
• Sanag B33S — biggest trade-off: It's a bone-conduction open-ear design with no active noise cancellation, so it won't isolate you from a noisy workplace.
• Jabra Perform 45 — biggest strength: Purpose-built push-to-talk with a noise-cancelling mic that removes up to 93% of background noise, made for shift work and retail floors.
• Jabra Perform 45 — biggest trade-off: It's a mono, work-first headset with no built-in music storage and only IP54 protection, so it isn't a swim or pool companion.
• Who each pick is for: Sanag B33S for swimmers, runners and cyclists who want open-ear audio and offline music; Jabra Perform 45 for retail staff, warehouse teams and anyone using a walkie-talkie app at work.
The Sanag B33S is a bone-conduction, open-ear headset, and its identity is clear from the spec sheet: IPX8 waterproofing rated for full submersion up to two meters, a one-piece hole-free shell, and a magnetic drive oscillator that keeps low-frequency detail intact even underwater. That combination is rare. Most sport earbuds handle sweat and rain; this one is designed to be submerged, which is why it's aimed squarely at lap swimmers, pool trainers and open-water swimmers.
The second half of the story is the 32GB of built-in memory. That's the feature that makes the B33S genuinely different from a typical Bluetooth headset. You can load thousands of songs onto the headset and play them in MP3 mode with no phone in the water at all — a practical necessity, since Bluetooth signals don't travel underwater. Bluetooth 6.0 covers everything above the surface: pairing within about three seconds and a stable connection up to roughly 50 feet. Battery life is 8 hours of continuous playtime from a 2-hour charge, which comfortably covers long swim sessions, meets and day-long outdoor training.
Who should buy it? Swimmers first, then runners, cyclists and anyone who wants to hear traffic and surroundings while training. The open-ear bone-conduction design deliberately leaves your ears open, which is a safety feature for road running and cycling. The built-in mic with ENC handles calls in noisy gyms or outdoor settings, and the whole thing weighs 21 grams, so it stays out of the way. Controls are physical push buttons, which is the right call when your hands are wet or gloved.
Jabra Perform 45: Who It's For
The Jabra Perform 45 SE is a completely different animal: a mono, on-ear Bluetooth headset engineered for push-to-talk communication on the job. The headline capability is PTT out of the box — a dedicated button that transmits your voice, working with the Walkie Talkie app in Microsoft Teams, Zello and Zebra Workcloud Sync. If your team already coordinates over one of those, the Perform 45 slots straight into that workflow instead of forcing you to build a new one.
Audio is tuned for voice, not music. The noise-cancelling microphone removes up to 93% of background noise while optimizing the wearer's voice, and the 10mm speaker is there so you can hear and be heard clearly. The frequency range (85 Hz to 255 Hz) and passive noise cancellation confirm the intent: this is a speech-first headset, not a hi-fi listening device. For someone calling across a noisy sales floor or a warehouse, that's exactly the right trade-off.
The design details are all workplace decisions. It weighs about 20 grams — roughly the same as four plastic credit cards — can be worn on either ear, and ships with three sizes of EarGels, with medium fitted by default. It's IP54-rated for dust and splashes, which suits retail and light industrial environments rather than pools. Face2Face Mode is a nice practical touch: lift the boom to mute incoming audio so you can talk to a customer, lower it to resume team comms. Battery life is strong for shift work at up to 11 hours of talk time, 20 hours of push-to-talk time and 9 days of standby, recharging in about 2 hours.
Who should buy it? Retail associates, warehouse and logistics staff, security teams, hospitality workers and anyone whose day revolves around quick voice coordination. Who should skip it? Swimmers, obviously, and anyone who mainly wants to listen to music during workouts — there's no onboard music storage and the tuning is voice-first. If you want one headset for both the pool and the job site, neither product covers both.
• Best for swimming and water sports → Sanag B33S. IPX8 submersible to 2 meters versus the Perform 45's splash-resistant IP54.
• Best for music without a phone → Sanag B33S. 32GB of built-in MP3 storage; the Perform 45 has none.
• Best for battery in a work shift → Jabra Perform 45. Up to 11 hours talk time and 20 hours PTT versus the B33S's 8 hours of playtime.
• Best for clear calls in noise → Jabra Perform 45. The mic removes up to 93% of background noise; the B33S relies on ENC and an open-ear design.
• Best for staying aware outdoors → Sanag B33S. Bone conduction leaves your ears open for traffic and surroundings.
• Best for team coordination at work → Jabra Perform 45. Native push-to-talk with Teams Walkie Talkie, Zello and Zebra Workcloud Sync.
• Best for wearing on either ear with size options → Jabra Perform 45. Three EarGel sizes and either-ear fit.
• Best for lightweight all-day sport wear → tie on weight. The B33S is 21 g and the Perform 45 about 20 g, so both are easy to forget you're wearing.
If I had to pick one, it depends entirely on your day — and that's the honest answer here. For anyone whose priority is swimming, running or cycling with music and no phone, I'd buy the Sanag B33S; its IPX8 rating and 32GB of storage are the two features that actually solve that problem. For anyone who spends their shift on their feet coordinating with a team, I'd buy the Jabra Perform 45 — the PTT button, 93% noise-removal mic and 11-hour talk time are built for exactly that. In my opinion, these aren't competitors so much as two tools for two different jobs. Pick the one that matches your routine, then check the current price on Amazon before you commit.
Yes. The B33S carries an IPX8 rating for full submersion up to 2 meters and has 32GB of MP3 storage so you can play music without Bluetooth underwater. The Perform 45 is only IP54, which covers dust and splashes, not swimming.
It connects over Bluetooth 5.3 and can handle audio, but it's voiced-tuned — the frequency range is 85 Hz to 255 Hz with passive noise cancellation. It's designed for calls and PTT, not for listening to music during a workout.
The Jabra Perform 45 is rated for up to 11 hours of talk time, 20 hours of push-to-talk time and 9 days of standby. The Sanag B33S is rated for 8 hours of continuous playtime. Both recharge in about 2 hours.
Not for music. Its 32GB of built-in memory lets you play songs in MP3 mode with no phone at all — which is also the mode you must use while swimming, since Bluetooth can't transmit underwater. Bluetooth 6.0 is for everything above the surface.
