I-Tech X-Perience

A little pricy but great for your on flight needs like chargers cases and earphones. Look for Vinny he’s great! They take credit card

I was impressed.
I stopped in just because I had lost my noise-​canceling headphones, and absolutely hate flying without. I was prepared to hate the service, and hate the prices — I was pleasantly surprised by both.
The man who was managing the store the day I was there knew his inventory very well; he could tell me the differences between different models on display, and the pros and cons of each given my wants — I asked for noise-​canceling, under $ 200, balanced audio (without the Beats Audio irritating-​to-​me pushed base), works as regular headphones without the battery.
Prices were only around 10−20% above Amazon, which for a small airport store is completely reasonable. They stock all the major brands you’d expect as well as some smaller niche brands I wasn’t that familiar with.
They specialize in headphones, but also have all sorts of other electronics you might forget and need at an airport; think cell phone chargers, cell phone cases, laptop bags, SD cards, etc.
The real name of the store is i-​Tech X-​Perience or Xperience — not Experience.
