Subynanal USB c to 3.5mm Headphone and Charger Adapter,2 in-1 USB C PD 3.0 Charging Port to Aux Audio Jack and Fast Charging Dongle Cable Cord for iPhone 17 Iphone16, iPhone 15, Galaxy (Gray)
Quick take
This Subynanal 2-in-1 adapter turns a single USB-C port into both a 3.5mm headphone/AUX connection and USB-C PD fast charging (up to 60W). It’s a good option for drivers and travelers who need wired audio from phones without a headphone jack, but it has limitations: it does not support data transfer, and some phones may not behave consistently.
Pros and cons
Pros
- Combines wired audio (3.5mm) with USB-C PD charging in one compact adapter.
- Supports fast charging up to 60W PD 3.0.
- Works with CTIA and OMTP style headsets, so mic/headphone setups are more likely to be compatible.
- Plug-and-play design, no drivers or apps required.
Cons
- No data transfer support (it’s audio and charging only).
- Phone compatibility can be hit-or-miss on specific models, with occasional “nothing happens” scenarios reported.
- Some users report volume differences at the high end, depending on their audio device or expectations.
What buyers think
Buyer-review evidence points to two main themes. First, many people use this adapter to add an AUX-style connection when their phone lacks a 3.5mm headphone jack, including connecting to car stereos when Bluetooth is unreliable. Second, the experience is not perfectly consistent across all phones and setups. Some buyers report the adapter works as expected for regular headphone use and charging, while others report the adapter does not respond on certain Samsung Galaxy models or requires troubleshooting with other brands. Overall, the review evidence suggests it can be dependable for the right phone, but compatibility is a key factor to consider before you commit.
What it is and how it works
The Subynanal USB-C to 3.5mm + charging adapter is designed for situations where your device has only a USB-C port and no built-in headphone jack. With the adapter connected, you can use wired headphones or an AUX input (like a car stereo) while powering the phone through USB-C PD fast charging. It also supports audio calling and volume control while charging.
Key features that matter in everyday use
2-in-1 audio and USB-C PD charging
Instead of choosing between listening and charging, this adapter is meant to let you do both through the same USB-C connection. That makes it especially useful for long drives, commutes, and travel when you want wired audio without draining your battery.
Fast charging support (up to 60W PD 3.0)
It supports USB-C Power Delivery fast charging up to 60W (PD 3.0). Charging speeds depend on both the phone and the charger you use, so pairing it with a compatible PD wall charger is important if you care about maximum speed.
Headset compatibility (CTIA and OMTP)
For wired headset use, it’s built to support CTIA and OMTP standards. That can reduce the chance of “mic works but audio doesn’t” or “no mic” issues when using certain third-party headsets.
Audio quality claims and the practical takeaway
The product emphasizes a built-in DAC chip and supports high-quality audio formats up to 32-bit and 384 kHz. While real-world sound depends on your headphones, the practical benefit is that it’s intended to deliver a stable wired audio signal rather than relying on Bluetooth conversion.
Compatibility notes and limitations
This adapter is intended for many USB-C devices, including iPhone 15 and iPhone 16 series, several Samsung Galaxy and Note models, iPads, and other USB-C phones/tablets. That said, buyers have reported that it may not behave properly on certain devices, so it’s wise to double-check your exact model fit before relying on it daily.
Important limitation: it does not support data transfer. If you need USB-C accessory functions like syncing to a computer or transferring files, this is not the right category of adapter.
Pros and cons (expanded)
Pros
- Useful for car audio and AUX setups: It can be a workaround when your car’s Bluetooth pairing is unreliable or limited.
- One-port solution: Designed to combine wired audio and PD charging without adding extra dongles.
- Fast-charging capability: Up to 60W USB-C PD 3.0 support can help if your charger and phone support it.
- Headset standard support: CTIA and OMTP support improves odds for common headphone and mic configurations.
Cons
- No data transfer: You only get audio and charging, no syncing or file transfer.
- Compatibility variability: Some phone models may not detect or respond correctly.
- Potential volume mismatch: A few buyers mention differences at maximum volume compared with other adapters, which may matter if you listen loudly.
Who should buy it
- You want wired headphones or wired car/AUX audio from a USB-C-only phone.
- You travel or drive often and prefer charging without giving up your audio connection.
- You use a compatible wired headset and want broader mic support (CTIA/OMTP).
- You need a budget-friendly dongle solution (and understand you are trading off data transfer features).
Who should avoid it
- You need a USB-C adapter that supports data transfer. This one is audio and charging only.
- You have a phone model that has been finicky with USB-C audio adapters in the past. Consider testing expectations or having a backup adapter option.
- You’re extremely sensitive to output volume matching and expect “exactly the same as a true headphone jack.” Adapter behavior can vary.
Verdict
The Subynanal 2-in-1 USB-C to 3.5mm headphone and PD fast-charging adapter is a practical choice for anyone who needs wired audio and charging at the same time, especially for car AUX setups. The main caveats are straightforward: it does not support data transfer, and compatibility can vary by device. If your phone is on the supported list you care about and you’re mostly focused on audio plus charging, it can be a useful low-fuss upgrade.
FAQ

That is the intended use. It supports USB-C PD fast charging while also providing a 3.5mm audio connection for playback and calls.

It lists compatibility for multiple iPhone, Samsung Galaxy, and other USB-C devices. However, buyer reports suggest some specific models may not work reliably, so it’s worth confirming your exact phone model before relying on it.
