iFi Headphone Adapter 3.5mm to 4.4mm

The iFi Headphone Adapter 3.5mm to 4.4mm is a compact, purpose-built solution for using your favorite 3.5mm single-ended headphones or IEMs with devices that feature a 4.4mm balanced headphone output. As 4.4mm “Pentaconn” outputs become more common on modern DAC/amps and portable players, this adapter lets you keep your existing 3.5mm gear in rotation without changing cables or replacing headphones. Simply plug the adapter into the 4.4mm output, connect your 3.5mm headphone plug, and you’re ready to listen. It’s an easy, travel-friendly way to improve compatibility across today’s headphone sources and legacy 3.5mm audio equipment.

What It's Good At:

• Making 3.5mm single-ended headphones compatible with 4.4mm balanced-output devices
• Keeping your current headphone/IEM cables usable as you upgrade to newer DAC/amps and players
• Quick, no-fuss connectivity for desktop, portable, and on-the-go listening setups
• Reducing cable swapping by acting as a simple bridge between common headphone plug standards
• Lightweight portability—easy to pack in a case, pocket, or accessory pouch
• A clean, dedicated adapter option for day-to-day headphone listening

iFi Headphone Adapter 3.5mm to 4.4mm Q&A:

What does the iFi 3.5mm to 4.4mm Headphone Adapter do?

It allows you to use headphones or IEMs with a 3.5mm single-ended plug on devices that have a 4.4mm balanced headphone output.

Is this adapter meant for headphones or for connecting to speakers/amps?

It’s designed for headphone listening use—connecting a 3.5mm headphone plug to a 4.4mm headphone output.

Will this make my 3.5mm headphones “balanced”?

No. It’s a compatibility adapter that lets a 3.5mm single-ended plug work with a 4.4mm output; it does not convert a single-ended headphone cable into a true balanced headphone connection.

When would I need a 3.5mm to 4.4mm adapter?

You’ll want one when your DAC/amp or portable player uses a 4.4mm output, but your headphones/IEMs still terminate in a standard 3.5mm plug.

Is it bulky or hard to carry?

No—it's compact and lightweight, making it easy to store in a small case or travel pouch.

Can I use this with iFi products and non-iFi devices?

Yes. It’s intended for any device that provides a 4.4mm balanced headphone output and for any headphones/IEMs that use a 3.5mm single-ended plug.

Does this require power, drivers, or setup?

No. It’s a passive adapter—just plug in and use.

What warranty coverage does it include?

It includes a 12-month warranty period.
