True Wireless Earbuds: What Actually Matters

ANC, battery, fit and codecs — separate the specs that matter from the ones that don't when buying earbuds.

Earbuds specs are a minefield. Here's the honest breakdown of what changes your daily experience — and what's just a number on a box.

Fit beats everything

No driver or codec matters if the buds fall out or hurt after an hour. Check the bud weight (under 5g is ideal), and whether the tips come in multiple sizes. Sport models with ear hooks are worth it if you train.

ANC is the biggest 'feel' upgrade

Active noise cancelling transforms commutes and open-plan offices. Even a modest hybrid ANC (35dB) noticeably silences the rumble around you. If you don't travel or work in noise, it's skippable.

  • ANC — worth it for commutes and offices
  • Transparent mode — lets you hear surroundings safely
  • Battery — aim for 6h+ per charge, 24h+ with case
  • Wireless charging on the case — genuinely convenient
  • Low-latency mode — only if you game
Buy for fit, then ANC, then battery. Everything else is nice-to-have.
