SIXSIM USB C to 3.5mm Headphone and Charger Adapter for Samsung

What buyers think

Buyer-review evidence is generally positive about daily usability. Multiple reports mention the adapters restoring wired headphone use on newer Samsung phones, working well in car setups, and staying secure when plugged in. Buyers also commonly highlight that charging continues while using the 3.5mm jack, and that the 2-pack value is convenient. That said, review evidence includes limited but real concerns around one unit not performing as expected, and occasional audio noise or sound dropouts that seem tied to ensuring the connection is fully seated.

Who this adapter is for

This is the right kind of accessory if you have a USB-C phone that lost its 3.5mm headphone jack, but you still want wired listening (headphones, car AUX input, or devices that accept a 3.5mm plug). It is also a good option if you dislike Bluetooth for certain use cases and want to keep charging while listening.

Key features that matter in real use

2-in-1 USB-C split, charging included

The adapter combines a 3.5mm audio output with a USB-C power passthrough. It supports USB PD fast charging up to 60W, but for faster speeds, it is designed to be used with a PD wall charger.

Audio output and compatibility

The adapter supports analog output through a 3.5mm headphone jack and lists support for DAC/ADC audio handling and CTIA/OMTP compatibility (two common headphone standard families). That makes it more likely to work across different headphone and headset types, including wired headphones with microphone support if your phone expects that signaling.

No data transfer

It is intentionally limited to audio and charging functions. If you were hoping to use this adapter for things like file transfers or other USB data features, it is not the right tool.

Compatibility notes to check before buying

Use the compatibility list as your first filter, especially if you are trying to pair it with a specific Samsung or iPhone model. Also note the manufacturer’s stated limitation that it is not compatible with Moto phones and OnePlus phones. If you are outside the listed devices, it is safer to verify compatibility to avoid frustrating “it doesn’t work” scenarios.

Pros and cons of buying this type of adapter

Benefits

• You get wired audio back without sacrificing charging.
• With a 2-pack, you can keep one adapter at home and one in a bag or car.
• Manufactured audio standards support (DAC/ADC specs and CTIA/OMTP mention) can help reduce weird headphone behavior.

Tradeoffs

• You are giving up USB data capabilities, because this adapter is not meant to function as a full USB hub.
• Audio reliability may depend on a firm connection and proper seating of the plug, based on the limited review evidence around buzzing or sound stability.

Price and availability

This adapter is positioned as an affordable add-on for households that need wired audio compatibility across one or more phones. If you are choosing between a single-adapter option and a 2-pack, the 2-pack can be more practical when you want redundancy (for example, one in the car and one for travel).

Verdict

If you need a straightforward USB-C solution for wired 3.5mm audio while keeping your phone charging, this 2-in-1 adapter is a practical pick, especially for many supported Samsung Galaxy models. It is not for USB data transfer, and you will want to double-check compatibility for your specific phone. For buyers who care about having a backup adapter and using wired audio in everyday settings, the 2-pack format and charging passthrough are the standout reasons to buy.
