If you want a premium wireless headset with active noise cancelling and all-day battery life for remote work, choose Focal BATHYS Over Ear; if you need uncompromising open-back soundstage and studio-grade detail for critical listening at home, choose FiiO FT1. These two headphones sit in completely different worlds, yet they both promise high fidelity in their respective categories. One is a portable, connected companion designed to block out the chaos of daily life, while the other is a wired, stationary instrument built to reveal every nuance of a recording without any electronic interference.
• Focal BATHYS Over Ear: Delivers over 30 hours of battery life with active noise cancellation, making it ideal for travel and office environments, but requires charging and relies on digital processing that some audiophiles might find less natural than pure analog.
• FiiO FT1: Features a massive 95x86mm planar magnetic driver with an extended frequency response up to 40kHz for an incredibly wide soundstage, but lacks wireless connectivity and requires a dedicated amplifier to drive its sensitive drivers effectively.
• Who is this for?: The Focal is for the professional who needs to stay connected and isolated simultaneously, while the FiiO is for the home listener or audio engineer seeking the highest possible resolution in a quiet room.
The Focal BATHYS is engineered for the modern nomad who refuses to compromise on sound quality while commuting or working remotely. Its design prioritizes comfort and isolation above all else, utilizing refined real leather and microfiber materials on the headband and earpads. This construction isn't just about aesthetics; it provides genuine insulation against external noise, which is crucial when you are trying to focus on a Zoom call or need to immerse yourself in music during a flight. The aluminum-magnesium yoke ensures the unit remains lightweight despite its robust mechanical construction, allowing you to wear them for long stretches without fatigue.
For the remote worker, the active noise cancelling (ANC) technology is the defining feature. With two optimized modes and a transparency mode, the BATHYS adapts to your environment instantly. You can switch from deep silence to letting in ambient office chatter with a simple tap, ensuring you never miss a critical moment in a meeting while still enjoying your music. The battery life supports this lifestyle effortlessly, offering over 30 hours of continuous use with ANC enabled. If you forget to charge it one night, the fast-charging capability provides five extra listening hours from just a fifteen-minute plug-in, a feature that eliminates range anxiety during busy workweeks.

However, this product is not for everyone. If you prefer the raw, uncolored sound of a wired connection or dislike the idea of digital signal processing altering your audio, the BATHYS might feel too processed. Additionally, while it connects via Bluetooth 5.1 with support for high-quality codecs like Apt-X Adaptive, it still relies on a battery and internal electronics. If you are looking for headphones that can be used indefinitely without power or that offer a purely analog experience, this model demands a specific workflow that includes charging and managing wireless connections. It is best suited for those who value convenience and isolation as much as they value the French engineering behind its M-dome speakers.
The FiiO FT1 represents a different philosophy entirely, focusing on the purity of the acoustic signal rather than the convenience of wireless freedom. This is an open-back headphone, meaning it does not seal off your ears from the outside world. Instead, it allows air to pass through, creating a vast, natural soundstage that feels almost three-dimensional. The massive 95x86mm flat unit driver is significantly larger than standard dynamic drivers, and when paired with the ultra-thin 1μm diaphragm, it produces an exceptionally wide lateral image with almost imperceptible boundaries. This makes it an exceptional tool for anyone who needs to hear the subtle nuances of a mix, whether you are editing audio or simply listening to complex classical arrangements.
The construction of the FT1 relies on proprietary technologies that push the limits of what a diaphragm can do. The sapphire and aluminum dual-coating patent technology enhances frequency response across different bands, boosting high-frequency resolution while maintaining the conductivity needed for clarity. The uniform magnetic field design further reduces distortion by ensuring the diaphragm vibrates evenly, capturing details that smaller drivers simply cannot resolve. Because it is wired and uses a 3.5mm jack, there is no Bluetooth compression, no latency, and no battery degradation to worry about. The sound you hear is exactly what was recorded, delivered with a sensitivity that rewards a good source.
This headphone is strictly for the stationary listener. Since it is open-back, it offers no isolation; sound leaks in and out freely. Using these in a noisy coffee shop or a busy open-plan office would be futile, as the ambient noise would drown out the delicate highs and the bass would bleed out into the room. Furthermore, while the impedance is relatively low at 20 ohms, the planar magnetic nature of the driver often benefits from a dedicated amplifier to fully realize its potential. It is designed for the home studio, the quiet living room, or the dedicated listening desk. If your priority is immersion in the music itself rather than interaction with the physical world around you, the FT1 is the superior choice.
• Best for remote work and travel → Focal BATHYS Over Ear: Its active noise cancelling and 30-hour battery life make it indispensable for mobile professionals who need to block out distractions.
• Best for home listening and critical analysis → FiiO FT1: The open-back design and planar magnetic drivers provide a level of spatial accuracy and detail impossible to achieve with closed, wireless designs.

If I were setting up a workspace for myself today, specifically for the demands of remote work where meetings, calls, and focused listening sessions blend together, I would choose the Focal BATHYS Over Ear. The ability to toggle between deep noise cancellation and transparency mode gives me control over my environment that the FiiO FT1 simply cannot offer. While the FT1 is undeniably magnificent for pure music appreciation in a quiet room, the practical necessity of staying connected and isolated in a non-studio environment makes the BATHYS the more functional tool for my daily life. It balances the high-fidelity heritage of Focal with the modern requirements of a mobile workforce, ensuring I get excellent sound without being tethered to a wall outlet.
Only the Focal BATHYS is suitable for this purpose due to its active noise cancelling technology and closed-back design. The FiiO FT1 is open-back, meaning it will not isolate you from surrounding sounds and is better suited for quiet rooms.
While the FiiO FT1 has a manageable impedance of 20 ohms, its planar magnetic drivers often benefit from a dedicated amplifier to fully utilize their speed and detail capabilities, especially given the 40kHz frequency response.
The Focal BATHYS offers over 30 hours of listening time with active noise cancelling and Bluetooth enabled, and features fast charging that provides five hours of playback from just a 15-minute charge.
No, the FiiO FT1 is a wired-only headphone using a 3.5mm jack connection. It does not have Bluetooth or internal batteries, so it must be plugged directly into a device or amplifier.
