Sony's h.ear lineup of headphones have seen some discounts as of late, but this is the first time that the MDR-100AAP has seen a discount. Dropping from around $179 to just $99, over on eBay. This is indeed for a new model, and not a refurbished or used model either. eBay is only offering these at this price in the Viridian Blue color as well.
The Sony h.ear headphones are the company's latest version of high-end headphones. As noted in their name, these are high-resolution headphones, which are great for the audiophiles out there. These are not wireless headphones, which is why they are able to deliver high-resolution audio to your ears. They do offer a microphone and inline controls. This makes it easy to take phone calls with these headphones, without taking them off to talk to whoever is calling you. Now, you will need to make sure you have a phone, or another device that does have a 3.5mm headphone jack, since this is wired and does not use USB-C or Lightning (although a USB-C to 3.5mm adapter or dongle should work perfectly fine).
There is free shipping on these Sony h.ear headphones, they are shipping from within the US, so you'll get them pretty quickly. eBay is quoting that you could receive them as early as this Friday, May 26th. And due to the holiday on Monday, you could get them as late as June 5th if you order today.
