Basically your earbuds' cables act as an antenna and pick up the RF signal sent out by the gates to check for tags passing (which when present cause a specific signal to be picked up by the receiver in the gates which in turn triggers the alarm).

This is why studio monitors used in recording produce neutral sound as close to 1:1 as possible. Consumer audio gear, either because of being cheap or because of being intentionally biased, have a strong impact on the way playback sounds. These changes are designed such that they will play back a neutrally mixed sound to the best of the particular design's ...

This very much sounds like the plugs are incompatible. Compare the looks of the two headphone jacks (those you actually plug in in case you use some kind of adapter), in particular the number of rings on each. If there is significant difference, you likely need another adapter. With headphones, there can be impendance mismatch, but your panning symptom ...

Complicated question when you understand it: professional musicians normally test their music across a wide variety of setups prior to releasing to the public. That means they may have a variety of different pieces of hardware that they'll test prior to releasing to public. Obviously, you can replicate this is by testing with your own, your friends, and ...

No, they do not. It might be possible to cross-connect a short delay across the left and right channels in order to simulate two speakers in front of the head, but this is generally not done. The left channel - as supplied by the media file or stream is simply routed to the left ear-bud, and the right channel to the right ear-bud. Generally, no more complex ...

However, when panned fully to the left, the headphones appear to turn from stereo to monaural. This is the clue. For whatever reason, the left channel of your headphone amp is driving both channels of your ...

Many professional sound recording crew on big-budget productions use their earbuds with hearing-protectors over the top for critical monitoring in high noise situations. The COMFORT factor will be more a factor of the earbuds vs. the hearing protectors. Of course there are cheap, uncomfortable hearing protectors just as there are cheap, uncomfortable ...

While having tried those stuff only once - I'm not sure they are really that comfortable. An usual place one might find them is on construction sites where drilling is required or on a shooting range - perhaps a hardware store might have some on display for testing

The same thing happens to me, but it only happens in my local library (in Cardiff), not in shops. I'm guessing that the security tags in library books differ from those found on clothes in a shop as they require activation and deactivation rather than removal. The odd thing is that when it happened my first thought was essentially "I'd like to exploit this ...
