The Problem – Modern Phones Have Only One Port

Smartphones have abandoned the headphone jack, leaving users with a single USB-C port for everything. For example, you are on a long flight watching a movie with wired headphones, but your battery is running low. Similarly, you are on an important work call that requires both audio and a stable connection, but your phone needs charging. Furthermore, Bluetooth headphones are not always an option, as they require charging themselves and can introduce audio lag. As a result, you are constantly forced to choose between hearing your content or keeping your phone alive. This 2-in-1 usb c headphone adapter solves that problem. Consequently, you can listen to wired headphones while charging your phone at the same time.

Pack of 3 – One for Every Location

A single adapter is useful, but a pack of three is transformative. This value pack includes three identical adapters. Therefore, you can keep one at home, one at work, and one in your travel bag. For instance, leave one plugged into your bedside charger. Keep one in your car for navigation and charging. Store one in your laptop bag for travel. As a result, you are never caught without the ability to charge and listen simultaneously, no matter where you are.

Sharing with family members is another advantage. For example, give one to your partner and one to your child. Similarly, keep a spare in case one gets lost or damaged. As a result, this pack offers excellent value and peace of mind.

Dual Functionality – Charge and Listen Simultaneously

The core feature of this adapter is its ability to split the USB-C signal into two independent functions. Specifically, one branch provides a 3.5mm audio jack for headphones or auxiliary cables. The other branch provides a USB-C port for charging. Therefore, you can plug in your wired earphones and your charger at the same time. For instance, watch a movie on a plane while keeping your phone plugged into a power bank. Similarly, take a long work call while your phone charges at your desk. As a result, you never have to choose between audio and power.

High-Quality DAC Chip – Clear, Crisp Audio

Not all audio adapters deliver good sound quality. This adapter features a built-in high-quality DAC (Digital to Analogue Converter) chip. Specifically, the DAC converts digital audio from your phone into analogue sound that your headphones understand. Therefore, the audio is clear, detailed, and free from static or interference. For example, music sounds rich with good bass response. Similarly, phone calls sound natural and crisp. As a result, you do not sacrifice audio quality for convenience.

Fast Charging Support – Quickly Power Your Phone

Some adapters only support slow, trickle charging. This one is different. It supports fast charging protocols up to 60W Power Delivery (PD). Specifically, pass-through charging allows your phone to charge at its maximum supported speed. For example, a Samsung Galaxy S23 or Google Pixel charges from 0% to 50% in approximately 30 minutes while you listen to audio. Similarly, an iPhone 15 or 16 charges at full speed. As a result, your phone charges quickly, not slowly, when using this adapter.

Plug and Play – No Apps or Drivers

Some accessories require enabling developer settings or installing apps. This adapter is different. It is truly plug and play. Specifically, connect the adapter to your phone’s USB-C port. Then plug your headphones into the 3.5mm jack and your charger into the USB-C port. Your phone immediately recognises both connections. For example, no settings to change, no drivers to install. Similarly, it works instantly on all compatible devices. As a result, you are up and running in seconds.

Real Use Cases for UK Users

Consider a commuter who travels by train for an hour each way. They want to watch downloaded Netflix shows on their phone, but the battery is low. Without this adapter, they have to choose between hearing the show (with wired headphones) or charging the phone. With this adapter, they plug in their charger and headphones simultaneously. Accordingly, they arrive at their destination with a fully charged phone and having enjoyed their show. As a result, the commute is productive and enjoyable.

Similarly, a remote worker takes long video calls on their phone. The call drains the battery quickly. They need to keep the phone charged while using wired headphones for privacy (or because their Bluetooth headset battery died). This adapter allows them to plug in the charger and headphones at the same time. For instance, they take a two-hour Zoom call while the phone stays at 100%. Consequently, they never have to scramble for a charger mid-call.

Furthermore, a driver uses an older car with only an AUX input (no Bluetooth). They also need to charge their phone while using navigation. This adapter allows them to connect the AUX cable for music and plug the charger into the USB-C port simultaneously. For example, long drives are more enjoyable with both power and entertainment. As a result, they arrive with a fully charged phone.

Likewise, a student in a library uses noise-cancelling wired headphones to study. They also need to keep their phone charged for a long study session. This adapter allows both. Consequently, they focus on studying without battery anxiety.

Universal Compatibility – Works with Most USB-C Devices

This adapter works with a wide range of USB-C devices that support audio and charging over USB-C. Specifically:

Samsung Galaxy:

• S20, S21, S22, S23, S24 series

• Note 10, Note 20 series

• A series (A53, A54, A55, etc.)

• Z Fold and Z Flip series

Google Pixel:

• Pixel 2, 3, 4, 5, 6, 7, 8, 9 series

Other Android phones:

• OnePlus, Xiaomi, Huawei, Sony, Motorola (check USB-C audio support)

iPhone 15 and 16:

• Works with USB-C iPhones for audio and charging

Tablets and laptops:

• iPad Pro and iPad Air (USB-C models)

• MacBook, Dell XPS, HP Spectre (limited USB-C alt mode support)

For example, a Samsung S23 user can charge and listen simultaneously. Similarly, an iPhone 15 user can do the same. As a result, check your device’s USB-C compatibility before purchasing.

Important – Device Must Support USB-C Audio

Not every USB-C device supports audio output. For example, some older Android phones or tablets may only support charging and data, not audio. Similarly, the Nintendo Switch does not output audio via USB-C (it uses a proprietary dock). Therefore, ensure your smartphone, tablet, or laptop supports USB-C digital audio. As a result, you avoid buying an adapter that will not work with your device.

What About Microphone Support?

This adapter typically supports the microphone on headsets with a 3.5mm TRRS plug (three black rings). For example, a headset with an inline microphone for calls will work. The microphone signal passes through the adapter to your phone. Therefore, you can take calls hands-free. As a result, it is perfect for voice calls, video meetings, and gaming chat.

What’s in the Box?

This pack of three includes:

• 3 x 2-in-1 USB-C to 3.5mm headphone and charging adapters

• No cables or chargers are included (use your own)

As a result, you receive three identical adapters ready to use with your existing USB-C cables and 3.5mm headphones.

Perfect for Families and Households

A pack of three is ideal for families. For example, give one adapter to each family member with a USB-C phone. Similarly, keep one in the car, one in the living room, and one in a travel bag. As a result, no more fighting over the single adapter when multiple people need to charge and listen at the same time.
