I bought the Sony XB950B1 Extra Bass Wireless Headphones from Amazon for US$98 during Black Friday 2017, down from US$128. They qualified for free AmazonGlobal shipping above US$125. The same headphones cost S$269 in Singapore, 50% more expensive.
I'd long wanted the Bose QuietComfort 15, or QC15, one of the best noise-cancelling headphones around. They're especially good for frequent travel, whether by plane or bus, cancelling out much of the engine noise.
I bought the Audio-Technica ATH-M50 Professional Studio Monitor Headphones, with coiled cable, from one of Amazon's Black Friday lightning deals for US$99.99, shipping included via AmazonGlobal Saver. In Singapore the ATH-M50 retails for S$238, so I saved a hefty S$112.
I bought the Bose AE2i Audio Headphones for S$239, down from S$269, at Stereo in Plaza Singapura. Atlas, the official Bose distributor, is marking its 50th anniversary with discounts on almost all Bose products until 31st October 2013.
As ever, I'm no audiophile, so forgive me if I don't dwell on audio quality. The Logitech UE 6000 retails for S$319 in Singapore, in black or white. It sits in the middle of the Logitech UE headphone range.
I'm no audiophile, but I can hear the difference between headsets. I don't own many, preferring earphones, my only one being the Nokia Purity HD Stereo Headset by Monster at S$298. The Logitech G930 Wireless Gaming Headset retails for S$249.
