Earbuds buying guide: ANC, codecs and fit explained simply

Earbud boxes are full of terms. Here is what each one means for you.

• ANC (active noise cancellation): reduces steady noise like traffic, fans and engines. Very useful for commuting.
• Transparency mode: lets outside sound in so you can talk without removing the buds.
• Codecs like AAC and LDAC: affect sound quality, but only if your phone supports the same codec.
• IP rating: IPX4 means sweat and splash resistant, good for workouts.
• Multipoint: connects to phone and laptop at once.

Fit matters most

Even expensive earbuds sound thin and leak noise if the tips do not seal. Try every tip size in the box.

Battery claims usually assume ANC off. Expect less when noise cancellation is on.
