What’s the Difference Between Line Out and Headphone Out?

The line out at the back of a TV is not the same as a headphone out, and plugging a wired headphone into it usually won't work properly. Here's the difference:

🔊 Line Out

• Fixed-level audio output (volume doesn't change with TV remote)

• Designed to connect to external amplified speakers, AV receivers, or amplifiers

• Low power – not meant to drive headphones directly

• Often labeled as: LINE OUT, AUDIO OUT (L/R), or RCA OUT

🎧 Headphone Out

• Variable volume – controlled by TV remote

• Provides enough power to drive headphones directly

• Typically 3.5mm jack on the side or front of TV (not the back)

🔌 If You Plug Headphones into a Line Out:

• You might hear something, but:

  • The volume will likely be very low

  • It may be mono or distorted

  • You risk damaging the TV or headphones (if impedance mismatch)

✅ Solution:

If your TV only has line out and you want to use wired headphones, you’ll need:

🔊 A headphone amplifier
→ Plug line out from TV → into headphone amp → then plug headphones into the amp.
