Last updated: October 11, 2026

Short answer: the Fosi Audio DS1 for better measured performance, the Samsung USB-C to 3.5mm Headphone Jack Adapter for the lower price. The Fosi Audio DS1 ranks #10 of 14 usb-c dongle DACs, rated 3.4/5, at $55.99. The Samsung USB-C to 3.5mm Headphone Jack Adapter ranks #11, rated 2.9/5, at $16.29, $39.70 cheaper.

Fosi Audio DS1 vs Samsung USB-C to 3.5mm Headphone Jack Adapter

The Fosi Audio DS1 is the better-sounding choice. Audio Science Review measured a SINAD of 104 dB, which is clean for nearly all listening. Watch for: Fosi Audio doesn’t publish a 32 ohm power figure, so it is hard to know which headphones it can drive well.

The case for the Samsung USB-C to 3.5mm Headphone Jack Adapter: It is a tiny, inexpensive way to add a 3.5 mm headphone jack to a USB-C phone or laptop, with volume handled by the device. The tradeoff: At 96 dB SINAD, sensitive in-ear monitors may reveal some hiss or noise.

Buy the Fosi Audio DS1 when measured performance outweighs the price for you, and the Samsung USB-C to 3.5mm Headphone Jack Adapter when the price outweighs measured performance instead.

Samsung USB-C to 3.5mm Headphone Jack Adapter ranking card

Pros: It is a tiny, inexpensive way to add a 3.5 mm headphone jack to a USB-C phone or laptop, with volume handled by the device. Audio Science Review measured a SINAD of 96 dB, clean enough for most headphones and well ahead of the far pricier AudioQuest DragonFly Red.

Cons: At 96 dB SINAD, sensitive in-ear monitors may reveal some hiss or noise. Samsung does not publish a power figure into 32 ohms, so it is best kept to earbuds and easy headphones. The FiiO KA11 rates higher, measures cleaner and is rated for 200 mW into 32 ohms for only a little more.
