Assessment scenario: Open-ear listening without a sealed canal tip
An editorial assessment scenario for a shopper considering an open-ear wearing style. This describes the wearing layout only; noise-control capabilities differ by exact model, and this is not a statement of the visitor's intent.
Explore this buying guide ↗Why consider this model?
- Samsung explicitly describes the Buds4 as open-type and says it has no silicone canal tip.
- ANC and Ambient Mode are also listed, so fit and noise-control capability are separate decisions rather than opposites.
- The case supports wireless charging; Samsung lists SBC/AAC/SSC, LC3 and a Galaxy-specific UHQ route with host restrictions.
Tradeoffs to weigh
- An open fit is not a sealed alternative; personal retention and the effect of ANC cannot be predicted from specifications.
- The five-hour ANC-on maximum is not codec-specific and is not a measured result.
- IP54 is limited to the earbuds; the case is not water resistant. The pad, USB-C cable and charger are not included.
- Samsung's Auto Switch is account-based across compatible Galaxy devices, not evidence of conventional two-host multipoint. No hands-on testing was performed.
Check these before ordering
- Match Black SM-R540NZKAXAR and check that the open wearing shape is acceptable.
- Confirm a compatible wireless pad is available and check that any cover fits the distinct Buds4 case.
- Keep the case dry; do not use the earbuds' IP54 rating as a case rating.
- Check the exact host and software for Galaxy-only settings and UHQ.
