Head-to-head
Cambridge P100 SE vs Focal Bathys: owner battery replacement or 192 kHz USB input
The short answer
Cambridge documents owner battery replacement, while Bathys accepts 192 kHz USB PCM and requires professional battery service. P100 SE is the stronger starting point when charging margin and home upkeep matter most. Bathys makes sense for a specific higher-rate USB requirement or a sound you prefer after an audition. Cambridge’s analog lead is proprietary, and Bathys still needs power for analog listening.
Before you choose
The reasoning and the trade-offs
A higher purchase tier can leave you more dependent on a service visit
If your one pair handles commuting, work and evening music, losing it to a battery problem can disrupt several routines at once. Cambridge documents replacing the battery with standard tools and the correct part. Focal requires professional battery replacement. P100 SE therefore offers a specific ownership advantage for someone comfortable following the approved procedure. Bathys may still be the better personal listening choice after a trial, but the premium does not buy a simpler battery-replacement job. Check parts and service availability for both, rather than assuming either route means an immediate repair.
What this is based on
Documented service requirements crossed with dependence on one daily headphone. No predicted failure rate, repair duration, price or lifespan is inferred.
Main trade-off
Focal Bathys
Battery service requires a professional, and an empty battery stops analog playback. Jack mode has no microphone, while USB calls exclude iOS.

- Main trade-off
- The USB-C-to-3.5 mm analog lead is proprietary. Keep it safe and check replacement availability before a trip.
Focal Bathys
- Choose it for
- Your source must send supported 192 kHz PCM directly and the 176.4 kHz exception is acceptable.
- A listening trial confirms that you prefer Bathys enough to accept its charging and service requirements.

About this comparison
Cambridge P100 SE vs Focal Bathys for long workdays, USB music and years of daily use. Compare charging conditions, cable replacement and the premium trade-off.
These are a music-focused ANC pair and a credible premium upgrade for the same desk-and-travel job. The upgrade is meaningful only if its specific input capability or auditioned listening preference matters.

What matters in practice
The differences that matter
A higher purchase tier can leave you more dependent on a service visit
If your one pair handles commuting, work and evening music, losing it to a battery problem can disrupt several routines at once. Cambridge documents replacing the battery with standard tools and the correct part. Focal requires professional battery replacement.

How we reached this conclusion
Documented service requirements crossed with dependence on one daily headphone. No predicted failure rate, repair duration, price or lifespan is inferred.
The charging comparison changes once you keep ANC on through the journey
P100 SE’s 100-hour headline drops to up to 60 hours with ANC enabled. Bathys lists up to 30 hours of Bluetooth listening with ANC. That gives Cambridge a larger published margin for someone combining a noisy commute with a long day of listening, but it does not prove twice the real runtime. Volume, codec and test conditions differ, and Cambridge says its app cannot force a lower codec. Bathys’s analog cable also requires charge, so packing it does not rescue a forgotten charging session. Compare the modes you will actually use and keep a practical charging routine.
How we reached this conclusion
Mode normalization across stated ANC-on figures, without claiming a matched-test ratio. Cambridge passive operation is not established here and is not used as a supposed advantage.
The cable you might lose can matter more than the maximum input rate
For ordinary desk listening through a compatible USB source, both accept digital music and retain saved EQ. Bathys goes up to supported 192 kHz PCM, while P100 SE reaches 96 kHz. That distinction matters if you have an actual source requirement, not simply because the larger number appears premium. For a shared television or seat headphone jack, a different issue comes first. Cambridge uses a proprietary analog lead and directs replacements through support. Bathys uses its supplied jack cable and also directs damaged-cable replacement through a dealer. Keep the correct lead with the case, especially if household cables are frequently borrowed or misplaced. Neither higher sample rate nor a generic USB-C adapter replaces that connection check.
How we reached this conclusion
Digital input ceilings separated from analog cable requirements and household cable handling. No universal third-party cable compatibility, audible high-resolution benefit or simultaneous wired-call feature is promised.
Check your own setup
Which headphones work with the way you listen?
Start with the way you listen. USB charging is not the same as USB audio, and some headphones need power even with a cable. These choices are examples until you apply yours.

Battery figures are manufacturer claims for the stated mode, not measured travel time. Volume, codec, calls and battery age change runtime. Closed earcups can still leak sound. Weight alone does not predict comfort. USB audio needs a compatible source and cable. This check does not assess sound quality, microphone quality or amplifier power.

Meaningful differences
What changes the fit
| What changes | Cambridge Audio Melomania P100 SE | Focal Bathys | Why it matters |
|---|---|---|---|
| Battery upkeep | Documented owner replacement with standard tools | Professional battery replacement required | The long-term maintenance route differs from the initial runtime. |
| ANC-on claim | Up to 60 h | Up to 30 h | These are different manufacturer conditions, not a matched endurance test. |
| Digital music input | USB up to 24-bit/96 kHz | USB up to 24-bit/192 kHz, excluding 176.4 kHz | Check the files and source output before paying for a larger input ceiling. |
| Analog cable | Proprietary USB-C-to-3.5 mm lead | Supplied jack lead, dealer replacement guidance | Do not treat every cable with the same connector shape as interchangeable. |
What you give up
Every choice has a cost
If you choose Cambridge Audio Melomania P100 SE
- The 100-hour claim is ANC off. Higher-bandwidth codecs and volume can reduce the 60-hour ANC-on figure.
If you choose Focal Bathys
- The 350 g headphone and supplied case need room. Driver materials and the higher USB ceiling do not prove better audible sound.
Recommendation switch
The decision flips if...
Owner battery replacement and charging margin matter most
Choose Cambridge Audio Melomania P100 SE. Cambridge documents the owner service route and higher ANC-on maximum.
A supported 192 kHz USB input is a real source requirement
Choose Focal Bathys. Bathys adds that compatibility without proving a sound-quality win.
What matters in practice
Before you choose
You want to spend more once and keep one good pair, but the premium model may add maintenance constraints rather than remove them.
What this comparison cannot tell you
- No measured sound, ANC, microphone, comfort or lifetime winner is claimed. Unverified passive playback and wired calling on Cambridge remain unknown rather than assumed absent.
