Listen and Charge at the Same Time
Many modern devices feature a single USB-C port instead of a traditional 3.5mm headphone jack. The ESR 2-in-1 adapter solves this limitation by providing two separate connections:
- 3.5mm audio port: Connect compatible wired headphones or earphones.
- USB-C charging port: Connect a compatible charger to power your device.
This allows you to enjoy wired audio while charging your smartphone or tablet through the same USB-C connection.
Up to 27W USB-C PD Fast Charging
The integrated USB-C charging port supports Power Delivery fast charging up to 27W. Connect a compatible USB-C PD power adapter to continue charging your device while listening to music, watching videos or taking calls.
Actual charging speed depends on the connected device, power adapter and supported charging protocol.
Hi-Res Audio with 96kHz/24-bit DAC
Featuring a built-in Hi-Res DAC chip, the ESR adapter supports audio output up to 96kHz/24-bit. This digital-to-analogue conversion technology helps deliver detailed audio through compatible wired headphones.
Enjoy music, podcasts, videos and other audio content through your favourite 3.5mm headphones without needing a separate audio converter.
CTIA and OMTP Headphone Compatibility
The adapter supports both CTIA and OMTP headphone standards, helping it work with a wider range of compatible wired headsets. This is useful when connecting different types of 3.5mm headphones and earphones.
Durable Braided Cable and Aluminium Housing
Designed for everyday portability, the adapter features a braided cable and high-quality aluminium housing. These materials provide a premium finish while helping protect the adapter during regular use.
Its compact construction makes it convenient to carry in a pocket, backpack or laptop bag.
Wide Device Compatibility
The ESR adapter is designed for compatible USB-C devices that support digital audio output. Published compatibility examples include selected Samsung Galaxy, Google Pixel, Huawei, Xiaomi and OnePlus devices, along with compatible iPad models.
Compatibility depends on the device's USB-C audio support. Check your device specifications before purchasing.
