SUNJOM Freepods SJ-0008 Over-Ear Headphones

The SUNJOM Freepods SJ-0008 are over-ear Bluetooth 5.4 headphones with active noise cancellation and a 3.5mm wired backup. They deliver up to 120 hours of playtime with ANC off at 50% volume. A 40mm driver unit produces Hi-Res Audio with a 120 decibel sensitivity and 32 ohm impedance. The set includes a travel case for portable storage.

Suits listeners who want multi-day battery life

Commuters and office workers gain up to 95% ambient noise reduction with a transparency mode for awareness. Multipoint pairing connects two devices at once with 13-second initial pairing and stable 10 metre range. Built-in ENC microphone ensures clear calls. Buyers needing more than 120 hours per charge or specialised gaming audio features should consider other options.

120-hour battery life with ANC off at 50% volume

This single figure defines the product's endurance ceiling for wireless listening. Active noise cancellation reduces the available playtime from this maximum. The 3.5mm connector provides a zero-latency wired fallback when the battery is depleted. No other specification overrides this operating-time limit for wireless use.

Questions about this item

How long before the 120-hour battery needs replacing?

The built-in cell delivers up to 120 hours with ANC off at 50 % volume; when capacity drops you can still listen through the 3.5 mm cable.

What stops the 40 mm drivers first during a long session?

Battery life is rated at 120 hours with ANC off at 50 % volume, so power runs out before the drivers hit any thermal limit.

How much heat or noise do the 40 mm drivers produce after hours of use?

Over-ear design with protein leather cushions keeps the 40 mm drivers cool and silent; no fan or audible hiss is present.
