Technics EAH-A1000 / Samsung Galaxy Buds3 (SM-R530)

The manufacturer says the Japan date may slip because of social conditions or supply; monthly production is stated as 2,000 units.

Listed by Panasonic as wireless stereo headphones.

Model code suffixes; the image shows the black (-K) version.

Technics also lists an SST edge and a flat baffle structure.

Technics says the SST edge comes from its SB-R1 flagship speaker.

Adjusts automatically to surroundings and fit.

ANC measures outside sound with microphones and produces an opposite wave to reduce steady hum; in an open design the effect is more limited than in sealed earbuds.

Technics says AI trained on human voices suppresses wind and background noise.

Band 2400-2483.5 MHz. LE Audio is supported; the Bluetooth version number is not given in the document.

Multipoint does not work when the LE Audio setting is set to prefer LE Audio. Of the 10 registered devices, at most 4 can be LE Audio.

Technics asks that the included USB cable be used.

Use requires settings in the Technics Audio Connect app and on the phone.

The manufacturer says times can be shorter depending on use.

Battery capacity (mAh/Wh) is not given.

No touch surface.

The manufacturer says the design aims to spread pressure across the head.

Sound Share works only between the same model.

The packaging is plastic-free.

The open design does not seal the ear canal, so it avoids a pressure feeling over long use but isolates less than tipped models. Fit varies with ear shape.

The VPU picks up the wearer’s voice through bone vibration to help separate speech in noisy calls.

UHQ (24-bit/96 kHz) only works on certain Galaxy phones and tablets with One UI 6.1.1 or later (S24, S23, Z Fold6/Flip6, Z Fold5/Flip5, Tab S9 series); 24-bit Hi-Fi needs One UI 4.0 or later. Other devices use AAC or SBC.

Samsung Seamless Codec (SSC) is Samsung’s own codec for higher-resolution wireless audio with Samsung devices. Auto Switch moves the connection between signed-in Galaxy devices automatically.

The SWIR infrared sensor detects whether an earbud is worn; the Hall sensor detects the case opening and closing.

These are Samsung’s internal tests with default settings paired to a Galaxy phone. Capacity is 48 mAh per earbud and 515 mAh in the case (typical).

IP57 means dust-protected and resistant to brief immersion; the charging case is not covered.

Some features are not available on non-Samsung devices.
