Pros and cons

Pros

Touch controls on the earbuds and claimed case touchscreen offer ways to manage playback and calls without reaching for a phone.
Sleep mode is specifically described as disabling low-battery and shutdown alarms, a useful consideration for overnight wear.
The claimed five EQ presets allow sound selection without requiring manual equalizer adjustment.

Cons

Noise control is listed as None, so these are not presented as active noise-cancelling earbuds.

What to know before buying

Listing details to confirm

The listing is contradictory about Bluetooth: the title and feature copy claim Bluetooth 5.4, while the technical details specify 5.3. The advertised 48-hour playback is total time, not a stated single-charge earbud runtime, and the page does not specify how that total is divided between earbuds and case. Check the selected listing for the Bluetooth version and the playback breakdown before buying. The listed color and 13mm drivers are listing claims, not independently confirmed.

Less suited to

Aggregate ratings are strongly positive overall, with most ratings in the five-star category, though a smaller share falls in the middle and lower categories. Without review comments, the ratings do not show what customers liked or disliked. For sleep use, fit, overnight comfort, and actual runtime matter, and the listing's total-playback claim does not specify earbud-only runtime.

Frequently asked questions

How long do the SU9 earbuds play on a charge?

The listing claims up to 48 hours of total playback, but does not state a separate runtime for the earbuds alone versus the charging case. Treat this as a combined figure and verify the breakdown if overnight runtime matters.

Which Bluetooth version does the SU9 use?

The listing conflicts: its title and feature text say Bluetooth 5.4, while its technical details say 5.3. Confirm the version for the selected listing.

Does sleep mode mute alerts?

The listing says sleep mode turns off low-battery and shutdown alarms. It does not establish that all other sounds or audio are muted.

Can I use the earbuds with a phone or laptop?

The listing names Bluetooth-enabled devices, cellphones, laptops, and tablets as compatible device types.
