I guess the answer to that is, “it depends”. And, it depends a lot on who you ask.
If you ask my new office-mate, the answer is likely yes. You see, a new person joined our group at work about 3 weeks ago, and due to an office space crunch, I’m sharing an office with him. Today, as he was wearing his headphone, I decided to crank up some music and get some work done.
I plugged in my headphone and proceeded to crank up the music. About 20 minutes later, he tapped me on my shoulder to ask me a question. As I pulled the headphones out of my ears, I noticed the music was still going … loud.
Yep, when you plug headphones into a Lenovo T61p laptop, it doesn’t kill the audio going to the external speakers from the docking station. So, for the last 20 minutes, I’ve been listening to headphones, and apparently everyone within about 20 feet of my office has been listening to my speakers. Epic fail.
