The BENFEI USB-C to Audio Jack Adapter brings a standard 3.5mm headphone port back to phones and tablets that dropped it, and it does the conversion properly: an onboard DAC smart chip handles decoding at up to 96kHz/24-bit, with signal-to-noise ratio above 100dB and THD+N under 0.01%. That spec sheet matters if you are plugging in wired IEMs or studio headphones rather than settling for whatever passthrough your phone offers. At 140mm (5.5 inches), the cable is long enough to route from a pocket or a laptop port without tugging, and short enough to stay in a bag. BENFEI rates the…

Frequently Asked Questions

Does this adapter work with the iPhone 15?

Yes. BENFEI lists the iPhone 15, 15 Pro, and 15 Pro Max as supported, along with Galaxy S21 through S24 Ultra, iPad Pro, and Pixel 8. Any USB-C device with audio output should work plug and play.

Will my headphone's inline microphone and volume buttons work?

They should. The adapter supports both OMTP and CTIA wiring standards at the chipset level with automatic detection, so wire controls and mic pass through without a switch or setting.

Is there an actual DAC inside, or is it just a passive adapter?

There is an active DAC smart chip. BENFEI rates it at up to 96kHz/24-bit, with SNR over 100dB and THD+N below 0.01%, which is why it works on devices that do not output analog audio over USB-C.

How long is the cable?

140mm, or 5.5 inches. That is long enough to clear a thick case or a crowded laptop port without strain, and short enough to coil into a pocket.

What happens if it stops working after a few months?

BENFEI includes an 18-month unconditional warranty with customer service contact. The cable is also rated for 30,000+ bend cycles, with strain relief at the connector where most adapters fail first.
