Panasonic has announced its new RB-HJ800 wireless headphones in Japan, with battery life of up to 100 hours on a single charge. The headphones also feature active noise cancellation (ANC), 40mm drivers and a dedicated Bass Enhancer function.

The new headphones are designed for users who want extended listening time without frequently charging their devices. Panasonic has also focused on comfort, offering soft headband padding, cushioned ear pads and a foldable design for easier storage. Here is everything you need to know about its specifications, features and pricing.

The Panasonic RB-HJ800 features a rounded over-ear design with a single-arm construction. The company has used Japanese traditional colours as inspiration for its three colour options: Shikkoku (black), Shironeri (white) and Umezome (pink).

The headphones feature soft padding on the headband and cushioned ear pads intended to reduce pressure during extended listening sessions.

Panasonic has also included a foldable mechanism that allows the headphones to be folded in two different ways, making them easier to store in a bag or other compact space.

The headphones weigh approximately 260 grams. However, they do not have an official water-resistance rating, so users should avoid exposing them to water.

Audio & Noise Cancellation

The RB-HJ800 comes with 40mm drivers designed to deliver sound across a frequency range of 20Hz to 20,000Hz.

One of its notable features is the built-in Bass Enhancer. A dedicated button allows users to switch bass enhancement on or off depending on their music preferences. This gives listeners an additional way to adjust the sound without relying entirely on software settings.

The headphones also support active noise cancellation, helping reduce surrounding noise during music playback and travel. An ambient sound mode is available for situations where users need to hear their surroundings.

However, Panasonic has not provided independent sound-quality or ANC performance measurements. The actual noise reduction and audio experience will need to be assessed through testing.

Battery & Charging

Battery life is the main selling point of the Panasonic RB-HJ800. According to the company’s specifications, the headphones offer different playback times depending on the connection type and noise-cancellation settings.

Panasonic claims that the headphones can deliver up to 100 hours of continuous playback over Bluetooth with ANC disabled. Enabling ANC reduces the rated playback time to approximately 72 hours.

The headphones take around four hours to charge fully through the USB Type-C port. They also support fast charging, with a 15-minute charge providing approximately eight hours of playback with ANC enabled and AAC audio.

These are manufacturer-rated figures, and actual battery life may vary depending on volume, settings and usage conditions.

Connectivity & Additional Features

The Panasonic RB-HJ800 supports Bluetooth wireless connectivity with SBC and AAC audio codecs. It has a maximum wireless communication range of approximately 10 metres.

Other features include:

One limitation is that the headphones do not support higher-quality Bluetooth codecs such as LDAC or aptX. They also lack water resistance.

Price & Availability

Panasonic has listed the RB-HJ800 wireless headphones at ¥14,850 (including tax) on its official Japanese online store.

Panasonic has not confirmed an Indian launch or international availability yet.

Final Verdict: Should You Consider the Panasonic RB-HJ800?

The Panasonic RB-HJ800 stands out primarily because of its claimed battery life. Its 100-hour playback rating with ANC disabled and 72-hour rating with ANC enabled make it an interesting option for frequent travellers and people who prefer headphones that do not require daily charging.

The 40mm drivers, Bass Enhancer and ANC provide additional features for everyday listening. However, the absence of advanced Bluetooth codecs and water resistance may disappoint some buyers.

At ¥14,850, the headphones could appeal to users prioritising battery endurance, provided their real-world sound quality and noise cancellation performance meet expectations.

Best for: Frequent travellers, commuters and users who prioritise long battery life.

Consider alternatives if: You want advanced Bluetooth codecs, water resistance or independently tested premium ANC performance.

Bottom line: The Panasonic RB-HJ800’s biggest attraction is its claimed 100-hour battery life. Its overall value will depend on how well its audio and noise-cancellation performance match its impressive endurance figures.
