Is the Samson SR350 good for studio recording?

Yes for light use. The closed-back cups limit bleed into a mic and the 32-ohm impedance works from most interfaces. It is not a flat reference headphone, so do not rely on it for critical mixing.

Does it have noise cancellation or Bluetooth?

No. It is fully wired with a 3.5 mm jack and only passive isolation from the closed cups. There is no battery, no wireless mode and no microphone.

Can a phone drive the SR350?

Yes. At 32 ohms and 110 dB sensitivity it gets loud from a phone or laptop headphone jack. A dedicated amp is not required.

How does it compare with the Samson SR850?

The SR850 is a semi-open studio headphone with a wider, airier sound that leaks more. The SR350 is closed-back, so it isolates better and suits noisy rooms and tracking.

The headphone with its attached 2.5 m straight cable and a 3.5 mm plug. A quarter-inch adapter is not always included, so check before buying for studio gear.

Are the earpads replaceable?

The pads can be pulled off and replaced, and third-party pads fit, but Samson does not sell them as a standard spare part everywhere. Expect to replace them as they wear.
