Bose has at least two main current earbud types on the market: the QuietComfort Ultra Earbuds and the QuietComfort Earbuds (2024). Recent coverage also points to a newer 2nd-gen version of the QuietComfort Ultra Earbuds, so depending on whether you count revisions, the total can be 2 or 3.

Quick breakdown

  • QuietComfort Earbuds (2024) — the entry/current standard pair.
  • QuietComfort Ultra Earbuds — the flagship pair.
  • QuietComfort Ultra Earbuds (2nd Gen) — a newer revision of the flagship model.

How to count them

If you mean distinct Bose earbud product lines , the answer is 2.
If you mean separate released versions including refreshes , the answer is 3.

Context

Review coverage in 2026 still describes Bose as having a small, focused earbuds lineup rather than many separate families. That usually means Bose keeps only a couple of active earbud models in circulation at once, with updates arriving as revisions instead of entirely new names.

In plain terms: Bose earbuds are more like a duo with occasional upgrades than a big lineup with lots of different series.

Count style| Answer| Why
---|---|---
Product lines| 2| QuietComfort Earbuds + QuietComfort Ultra Earbuds.
Released versions| 3| Adds the QuietComfort Ultra Earbuds (2nd Gen). 1

TL;DR: 2 main types, or 3 if you count the newer Ultra revision.
