The Fatman Apollo77 Hybrid Monitor Headphones feature a dynamic bass driver, two Knowles balanced armatures for midrange and treble, and a dedicated Knowles super tweeter balanced armature. These are integrated via a passive three-way crossover intended to ensure separation and balance across the frequency spectrum.


According to the supplied specifications, the Fatman Apollo77 Hybrid Monitor Headphones offer a frequency response from 10Hz to 24kHz, with an impedance of 28 Ohms at 1kHz and a sensitivity rating of 108dB. This combination positions them for use across a range of playback devices without excessive power requirements.
FATMAN APOLLO77 MADE IN THE UK
UK-designed and manufactured, with ACS, the acoustic design of the Fatman Apollo77 Hybrid Monitor Headphones incorporates an acoustically tuned sound path construction and an ACS passive ambient filter providing 17dB of isolation. CNC-machined stainless steel sound output nozzles are included, with interchangeable options supplied in standard, short, extended, and custom lengths.
FATMAN APOLLO77 BUILD AND MATERIALS
The Fatman Apollo77 Hybrid Monitor Headphones use die-cast aluminium housings finished in black anodising with threaded stainless steel nozzles and interchangeable metal faceplates, available in either chrome or rose gold. Connectivity is through a replaceable 2-pin (0.78mm) system paired with a high-purity, oxygen-free copper silver-plated cable.
Each pair of Fatman Apollo77 Hybrid Monitor Headphones comes supplied in a presentation box with a 3.5mm to 6.35mm jack converter, three sizes of ear tips, three nozzle options, and a leather-effect carry case with a carabiner. Optional extras include a Go Link headphone amplifier with DAC and custom-moulded silicone ear tips.

ARIA Award-winning and GRAMMY-nominated violinist Patrick Roberts cites them as his “go-to” headphones for both travel and home listening. Mo Pleasure, known for his work with Earth, Wind & Fire and Michael Jackson, describes the Apollo77 as offering “a wide soundstage, strong detail, and warmth across genres.”
