Inner Ear Headphone | Audio-Technica ATH-CK1

Got a pair of audio earPhone below S$35. Hope it blocks out most of the ambient noises on the plane. I intend to use that on the place to get better sleep and I think this is more comfortable than those headphones provided on the flight. It will be another long flight... Oh ya, I have left the RFID sticker tag on the box. FYI, it was covered by the price tag.
