Amazon offers Prime members the JLab J5 Metal Sport Earbuds in 10 colors (Blue Steel pictured) for $9.99 with free shipping. (Non-members can spend $35 or more to bag free shipping; otherwise, it adds $5.74.) That's the lowest total price we could find by $15 and the best per-pair price we've seen. (For further comparison, we saw two pairs for $25 last week.) These earbuds feature a gold-plated 3.5mm connector, 8mm titanium drivers, and four sizes of ear tips.

Update: Specs corrected.
