Product Description

UGREEN CM231 2-in-1 USB C to 3.5mm Adapter – Phone charging stops when you use wired headphones?

Modern smartphones removed the 3.5mm jack. That decision still causes daily frustration. Music pauses when the battery drops. Calls end early. Charging and audio should work together. The UGREEN CM231 2-in-1 USB C to 3.5mm Adapter solves that exact problem with a focused, practical design.

This adapter targets users who rely on wired audio but refuse battery anxiety. It sits in the Computer Accessories category under Converter and Splitters, designed by UGREEN, a well-known brand in digital connectivity solutions. The product is officially available through PCB Store in Bangladesh.

What makes the UGREEN CM231 2-in-1 USB C to 3.5mm Adapter different?

Many adapters promise audio and charging. Few deliver stable output without compromise. The UGREEN CM231 focuses on two priorities: uninterrupted sound and reliable power input. No data transfer. No extra ports. No unnecessary complexity.

The design uses a USB Type-C male connector on one side. The other side splits into a 3.5mm audio jack and a USB-C female charging port. This layout allows charging and listening at the same time without interference.

Short cable length reduces signal loss. Aluminum housing protects internal components from heat and wear. The adapter weighs under 20 grams, so it stays pocket-friendly.

UGREEN CM231 specifications and performance overview

The UGREEN CM231 model number 60164 uses a multiport converter format. It supports USB-C audio output combined with USB-C power input. Maximum charging capacity reaches up to 30W, suitable for daily fast charging needs.

Audio output supports up to 24-bit / 96kHz. This matters for users who notice compression or distortion. The sound remains natural and balanced with supported earphones.

Data transfer is intentionally excluded. That design choice improves stability and avoids conflicts between audio and power signals.

Key technical characteristics include:

• USB Type-C male input
• 3.5mm female audio output
• USB Type-C female charging port
• Power Delivery 3.0 support
• Quick Charge 3.0 support
• Aluminum alloy and TPE materials

The adapter supports earphones below 50 ohms. High-impedance headphones are not supported.

Audio quality and charging stability in real use

Audio adapters often struggle with noise, hissing, or sudden cut-offs. The UGREEN CM231 focuses on clean digital-to-analog conversion. Music plays without distortion. Voice calls remain clear.

Charging remains stable even during long listening sessions. Power input does not interrupt audio output. Heat buildup stays minimal due to the aluminum housing.

This adapter works best for commuters, students, and professionals who use wired earphones during charging. It fits desk setups, travel use, and everyday phone handling.

Power delivery support and efficiency

The UGREEN CM231 supports both PD3.0 and QC3.0 charging standards. This allows faster charging on compatible chargers and devices. Maximum supported wattage reaches 30W, enough for phones and tablets.

Charging performance depends on the charger and cable used. The adapter does not limit charging speed within its rated capacity.

Power efficiency stays consistent because data transfer circuitry is excluded. That keeps the internal layout simple and stable.

Device compatibility and supported platforms

Compatibility remains one of the strongest points of this adapter. It works with a wide range of USB-C smartphones and tablets that lack a headphone jack.

Supported devices include:

• Samsung Galaxy S22, S22+, S22 Ultra
• Samsung Galaxy S21, S20 series, S10 series
• Samsung Note 10, Note 10+, Note 20 series
• Google Pixel 2, 3, 4, 5, and XL variants
• iPad mini 6
• iPad Pro 2020 and 2021
• iPad Air 4 and 5

The adapter supports Android OS devices. For iPad Pro, earbud remote control is not supported. For OnePlus 3T, earphones should be connected before charging.

Build quality, design, and daily durability

The adapter uses aluminum alloy combined with TPE material. This improves durability while keeping weight low. The gray finish matches most modern devices.

Compact dimensions make it easy to carry without strain on the USB-C port. The reinforced housing protects against bending and daily wear.

This design choice suits users who frequently plug and unplug accessories throughout the day.

Reliability and warranty coverage

UGREEN provides a one-year brand warranty with the CM231 adapter. This warranty covers manufacturing defects under normal usage.

The brand has a strong reputation for cables and converters. This product follows the same reliability standards. PCB Store handles official distribution and warranty support in Bangladesh.

• Use wired earphones daily
• Charge phones while listening to music
• Prefer compact accessories
