The silver pair is a demo Focal Bathys Deep Black is a wireless noise‑cancelling headphone for customers who want genuinely hi‑fi sound in a travel‑ready, everyday form factor, with a darker, more understated finish than the original Bathys colours. Bathys is built around 40 mm aluminium/magnesium ‘M’‑shaped dome drivers made in France, derived from Focal’s full‑size hi‑fi headphones. The tuning aims for detailed, dynamic playback with controlled bass, natural midrange and clean, extended highs, so it feels more like a compact Focal hi‑fi component than a typical ANC Bluetooth headphone. Active noise cancelling offers multiple modes (Silent, Soft and Transparent), letting listeners either shut out the world on flights and commutes or maintain awareness when walking and working, with a transparency mode that keeps surroundings intelligible without heavily colouring the sound. Connectivity is deliberately flexible. Bluetooth 5.1 with multipoint pairing and codecs including SBC, AAC, aptX and aptX Adaptive covers phones, tablets and laptops with low‑latency, stable links. A built‑in USB‑DAC handles up to 24‑bit/192 kHz for higher‑resolution listening from computers or compatible devices, and a 3.5 mm input keeps Bathys useful with traditional analogue sources when you prefer not to run wireless. Eight microphones support both ANC and Clear Voice Capture for calls, while support for Google Assistant and Amazon Alexa, plus the Focal & Naim app, allows simple control, EQ tuning and personal hearing profiles. Battery life is rated at around 30 hours with Bluetooth and ANC, stretching to 35 hours in wired analogue mode and up to 42 hours when used over USB‑DAC. A fast‑charge function can add roughly five hours of listening from a 15‑minute top‑up, which makes Bathys practical for travel and long office days. The Deep Black edition keeps the same magnesium yokes, aluminium structure and soft leather/foam pads as the original, but shifts the aesthetic into a fully blacked‑out look that pairs neatly with other components and feels discreet in everyday use. For Hi‑Fi Centre customers who want a portable headphone that still behaves like a hi‑fi product—excellent drivers, proper DAC implementation, thoughtful noise control and long‑term comfort—Focal Bathys Deep Black is a strong fit in that role.
