Can't find too much information about the item in this first deal. 

On computer Lounge for $29 (down from $149). Listed for $59 usd on both the Hiby Store and Amazon US, which works out to $95ish nzd before shipping.  2.5mm jack. I think they're specifically for the R3 R6 bluetooth player .... but not entirely sure. Not my field of expertise. 

Here's a decent review of the headphones. If anyone has a better understanding, please fill me in. Keen to jump on a good deal.
