The earbuds buying checklist: what actually matters before the price tag

Earbuds are the most-bought and least-researched gadget in tech, which is why so many drawers hold a pair that almost worked. The marketing sells features; the daily experience is decided by seven unglamorous checks. None of them is the brand name.

The seven checks, in order

1. Fit and isolation come before everything. Two identical earbuds can sound opposite on two ears - a bad seal eats bass first, so the "weak sound" complaint is usually a tip-size problem. Multiple tip sizes in the box, or a fit style you have worn happily before: that is check one, and it outranks everything below. 2. Battery honesty. The headline number is the case; the earbuds alone matter more - four to six hours per charge is the honest modern range, and anything under four makes long days into socket-hunting. Check the claimed hours for the buds, not the case. 3. Codecs: baseline is enough. SBC and AAC (the defaults on Android and iPhone respectively) carry the overwhelming majority of real listening; LDAC and aptX are nice on paper and audible on fewer occasions than the spec sheet implies. Do not pay a premium for a codec your phone cannot use - the same logic as buying phones by the specs that matter.

4. Noise cancelling: know what you are buying. Active noise cancelling hushes steady droning - planes, trains, fans - and does remarkably little against voices and sudden sounds. For commutes it is genuine; for an open office it is partial. Passive isolation from a good fit does half the work for free. 5. The call microphone. Music you hear is half the product; your voice on calls is the other half and almost never demoed. Look for reviews that test calls in wind and street noise - this is where cheap buds fail first. 6. Latency, if you watch video. Sound lagging the picture is the classic budget-bud failure; any modern pair with a low-latency mode or Bluetooth 5-era chip is fine. 7. IP rating, if they will sweat. The rating means exactly what it says and nothing more: IPX4 handles rain and workouts; nothing consumer-grade is for swimming.

Then, and only then, the price

Decide your three non-negotiables from the seven, ignore the rest of the sheet, and buy the cheapest pair that clears your three - the price bands move every season, but the checklist does not. The same discipline scales to bigger purchases: laptops by RAM and storage, monitors by the specs that matter, and the honest middle path of refurbished versus new.
