I think that the current suggested value's a bit too old.

My Steam inventory history isn't showing effects now so here's the seller's backpack at the time. http://backpack.tf/profiles/76561198035984179?time=1415123596 Please note that the earbuds are from me (the metal's not).

The seller had a buy-out price at 4.5 for 2 weeks so this purchase wasn't at a quick-sell price. Additionally, no others have been available since.
