What should I do if my MacBook headphone jack isn't working?
I've had this happen to me a couple times.First, try unplugging your headphones out and back in. Yes, sounds silly but sometimes it's that easy. (Happens sometimes if you can't seem to raise volume with keys on keyboard.If no luck...Try holding down the option key and click on the sound icon on the very top nav of your macbook. Doing this will reveal additional options(you can actually try this on most of the icons up there, like wifi). Check the "output device" and make sure it's not trying to send the audio elsewhere (such as apple tv). You should ideally see an option that says "headphones" on that list. Click it.If no luck..If you do not see headphones on the list described above, try a simple restart. That tends to get everything back to normal.
Headphone makes a low humming noise?
I just purchased the Monster Inspiration Active Noise Cancellation headphones. When I plug them into my Macbook Pro I hear a low humming/buffing noise in the background but it goes away after a while then comes back again. The weird thing is that when I physically put my hands on the mac, the sound goes away. Anyone know the reason why?
Why do my headphones make a static noise when I plug them into my computer? please help?
Your jack might either be dirty or damaged. Try using another headphone, if it fixes the problem, then the headphone you are previously using might have a broken wire or a damaged jack. Try to observe if the static sound crackles with the rhythm of the audio you are playing. If yes, a broken solder connection could be the problem. It could be fixed by re-soldering the connection to the motherboard... but let the experts do that, if in case you're inexperienced with those kinda stuff.
Why do headphones make low buzzing noises? Sometimes they are not fully plugged in.
Headphone plugs have a left, right, and ground loop. All three bands must meet the same three connectors inside the headphone jack. When you put the plug in partially, the three bands are open (not connected to the bands inside the jack) so any noise coming from the signal can be heard through the headphones. Once the plug is fully depressed, each band creates an infinite loop so all you should hear is music from the left and right channel while the ground is theoretically neutralized.

Abnormal situation with my Sennheiser HD 407 headphones?
This is problem is caused by poor grounding of the "common" lead on the headphones. (The wire that goes usually from the negative end of each speaker to the "Body" ,(this is the long metal part of the plug pin) of the headphone 3.5mm "jack" plug The screen lead which grounds the headphones to whatever you plug them into is not connecting effectively, thus the screen wire inside the headphone cable is acting like a radio antenna. The "Buzzing" noise you refer to is due to pickup of mains frequency radiating from your house power cables, or electronic equipment nearby. When you touch a metal part of the computer you are effectively becoming a ground to the mains, (pickup), hum. If this only happens when you connect to your computer then it must be either a dirty contact on the computer earphones socket or a poor solder joint on the computer end. (You could try plugging the jack in and out several times to see if it gets better, otherwise you'll need to get the computer repaired). If the problem happens whatever you plug the Headphones into then you need to check the headphone lead. Some Sennheiser Headphones have user replaceable leads. You might be able to obtain a spare lead from your Sennheiser dealer in that case.
Which has a better quality, plugging my headphone jack directly to my laptop or plugging it to my audio interface?
I'm assuming by Audio Interface you're either referring to an external USB sound card or a USB DAC. If so, then either of these are significantly better in sound quality than your internal audio jack.For example, a Macbook has the following specs:Jack type: 3.5 mm stereo Maximum output voltage: 2 VRMS (+8.24 dBu) Output impedance: < 24 Ω Frequency response: 20 Hz to 20 kHz, +0.5 dB/-3 dB Signal-to-noise ratio (SNR): > 90 dB Total harmonic distortion + noise (THD+N): < -80 dB (0.01%) Channel separation: > 75 dBAnd, the Sound BlasterX G6 has the following specs:Dynamic Range: 130dB (A-weighted), THD+N: ~0.0002%, Sampling Rate (DSP Playback): PCM 16/24/32-bit / 44.1, 48.0, 88.2, 96.0kHz, Sampling Rate (Direct Mode Playback): PCM 16/24/32-bit / 44.1, 48.0, 88.2, 96.0, 176.4, 192.0, 352.8, 384.0 kHz, DoP 24-bit / 176.4 , 352.4 kHzThat 130 db is considerably cleaner, louder , and better than the Macbook headphone jack.
What happens if you connect an aux cable to phone and a laptop?
Interesting proposition, but you are connecting a cable onto the audio outs of two devices, which leads to nothing at all. So what you would be hearing is silence.
