Look for a set of core specs you need – driver size, frequency response, connectivity, battery life if it matters. Make a simple list in a spreadsheet with price, seller, warranty, return policy. Use price‑tracking tools like Honey or CamelCamelCamel for Amazon, keep a note of historical lows. Add a column for any available coupons or cashback offers. When a price hits your target, snap it. Check third‑party sellers for bulk discounts or open‑box items; they’re usually in perfect condition. And don’t forget to read recent reviews – quality is a hard‑to‑measure thing, so if a cheaper model gets a lot of complaints, skip it. That’s the only systematic way to keep quality and savings in sync.
