Thumb Score: +9 Hey folks, buydig via eBay is offering HIFIMAN HE-400i SE Over-Ear Headphones [ebay.com] for $149.99. This deal went frontpage two months ago. Now coupon code PRIMO119 brings the price down to an all-time low of $124.99. I bought these headphones for about $225 a couple of years ago and still think they're fantastic for the price - at $100 less, they're a steal!
