iDiskk Hybrid ANC Headphones | Bluetooth 5.3, 35–40H ANC Playtime, 40mm Drivers, FF+FB Noise Cancellation, USB-C, Aux-In, Foldable | Light Grey

iDiskk Hybrid Active Noise Cancelling Headphones — Bluetooth 5.3, Feed-Forward + Feed-Back ANC (25–32dB NC Depth), 40mm Drivers, 35–40 Hours Playtime (ANC On), 60 Hours Maximum, USB-C Charging, 3.5mm Aux-In, 6-Month Standby | Light Grey

Over-ear wireless headphones from iDiskk with a fully specified Hybrid ANC system. Unlike generic “ANC” headphones that state noise cancellation without technical details, iDiskk publishes the full specification on the box: FF+FB hybrid topology (Feed-Forward external microphones plus Feed-Back internal microphones), 25–32dB noise cancellation depth, 40mm drivers, and a 600mAh battery. Bluetooth 5.3. USB-C charging. 3.5mm wired mode. Foldable. Certified CE, UKCA and FCC. 8 units available at £29.99.

ANC System in Detail

• Hybrid ANC topology: FF+FB (Feed-Forward + Feed-Back) — this is the same dual-microphone architecture used in premium ANC headphones; Feed-Forward microphones sit on the outside of the ear cup facing outward, detecting incoming ambient noise before it enters the ear and generating a cancellation signal in advance; Feed-Back microphones sit on the inside of the ear cup facing the ear, monitoring what sound actually reaches the ear after the FF signal is applied and making real-time corrections; the combination of both types produces more consistent cancellation across a wider range of noise frequencies and at varying noise levels than a single-microphone ANC system
• NC depth: 25–32dB — the noise cancellation depth is the amount of ambient sound (in decibels) attenuated by the ANC system; 25–32dB is a meaningful range; as a reference point, a 10dB reduction halves the perceived loudness of a sound; 25dB represents a significant reduction in continuous ambient noise such as air conditioning or motorway traffic; 32dB at the upper end brings it close to the performance of mid-range dedicated ANC devices
• Frequency range: 20Hz–20kHz — the full range of human hearing; the drivers reproduce the complete audible spectrum from the lowest bass to the highest treble
• S/N ratio: 85dB — the signal-to-noise ratio measures how much louder the audio signal is than the background electrical noise floor of the headphone; 85dB is a solid figure for a wireless headphone at this price point, indicating a clean audio output with minimal hiss
• Distortion: ≤1% — total harmonic distortion of 1% or below is considered low for a consumer headphone; distortion above 1–2% becomes audible as a colouration or harshness in the sound, particularly in bass frequencies; ≤1% means the drivers are reproducing the signal accurately at normal listening levels
• 40mm drivers — the driver diameter directly affects bass response and overall sound volume capability; 40mm is the standard size for over-ear consumer headphones and is sufficient to produce a full-range sound with adequate bass weight

Battery & Connectivity

• 35–40 hours playtime (ANC on) — this is the honest ANC-active figure from the box specification panel; the marketing imagery also references 60 hours, which reflects maximum playback with ANC off; 35–40H with ANC on is the relevant figure for daily use; at 3–4 hours of listening per day with ANC active, a full charge lasts approximately 9–13 days
• 600mAh battery — the battery capacity is stated on the box; 600mAh is a moderate capacity for a Bluetooth headphone and consistent with the 35–40H ANC-on figure
• 6-month standby (power off) — when powered off rather than in sleep mode, the headphones can hold charge for up to 6 months; relevant for occasional-use scenarios such as travel headphones stored between trips
• Bluetooth 5.3 — current mainstream standard; improved connection stability and power efficiency over earlier versions
• Transmission distance: ≥15m — in open conditions, the Bluetooth connection maintains at 15 metres or greater from the source device
• USB-C charging — visible on the bottom edge of the ear cup in the product images; USB-C is the current universal standard, eliminating the need for a proprietary or Micro-USB cable
• 3.5mm Aux-In wired mode — also visible on the bottom edge; allows wired connection to any device with a 3.5mm output, including in-flight entertainment systems, non-Bluetooth devices and situations where Bluetooth is restricted; wired mode works independently of battery level

Design & Certifications

• Foldable design — the ear cups fold inward for compact storage; suitable for bag and case storage during travel
• iDiskk gold branding — gold iDiskk lettering on the outer face of each ear cup with a yellow lightning bolt accent icon; clean, minimal branding against the light grey body
• Colour: Light Grey — iDiskk describes this colourway as Grey; in the product images the finish is a very light grey, close to off-white, with a matte surface; the gold lettering and yellow accent provide the only colour contrast
• Certifications: CE, UKCA, FCC — CE and UKCA mark UK/EU electrical safety and EMC compliance; FCC certification covers US radio frequency compliance; all three marks are printed on the product box and visible in the packaging image
• Manufacturer: ShenZhen FeiTianXia Technology Ltd. — printed on the box; iDiskk is the consumer brand
