USB-C in-ear headset for phones and laptops

The Plantronics A1 is a wired USB-C headset with 8 mm drivers, 32 ohm impedance and a frequency response of 18 Hz to 20 kHz. It delivers up to 100 dB output and includes an in-line volume control and microphone. The package contains two extra silicone tips in small and large sizes for fit adjustment. It is intended for users with USB-C devices that lack a 3.5 mm jack.

Check your device USB-C audio routing before

Some phones require the USB audio routing setting to be disabled in developer options for sound to work. On laptops and desktops the default input and output device may need to be changed to the USB headset in sound settings. The headset uses a USB-C connector only; it will not fit devices that provide only a 3.5 mm port. No adapter is included in the box.

Replaces basic bundled earbuds or dongle solutions

The jump is worth it when you want a single cable with integrated DAC, microphone and volume control instead of a separate adapter and 3.5 mm earphones. It suits buyers who need a secure in-ear fit with noise isolation for calls and media on the move. It is not for listeners who prefer over-ear comfort, wireless freedom or a detachable cable design.

Questions about this item

Does the Plantronics A1 USB-C headset include extra ear tips or do I need to buy them separately?

The package includes two additional silicone tips in small and large sizes, so no separate purchase is needed for a secure fit.

Which version of the Plantronics A1 should I choose for a USB-C phone without a 3.5 mm jack?

This model uses a USB-C connector and is intended for devices that lack a 3.5 mm port, such as recent Samsung Galaxy, iPhone 15/16 series, Google Pixel and compatible laptops.

What does the 100 dB sensitivity rating mean when I plug the headset into my laptop?

At 100 dB sensitivity and 32 ohm impedance, the 8 mm drivers will reach loud listening levels from a standard USB-C audio output without requiring an external amplifier.
