What to know before buying

Listing details to confirm

The listing's Bluetooth details are inconsistent: one highlight says Bluetooth6.0, while the dedicated version field says 5.1. Confirm the version and whether a cable is supplied, since the listing names Cable as built-in media but also says No Jack. Waterproofing is claimed without a stated rating, and the listed five-year warranty is not accompanied by terms.

Who is it for?

A good fit for

Listeners seeking foldable over-ear headphones for commuting, travel or everyday use.
Buyers who want listed active noise cancellation and wireless connection to a cellphone.

Less suited to

Buyers who need a confirmed Bluetooth version, a specified water-resistance rating or documented warranty terms before choosing.

Customer feedback highlights sound quality, comfort, connectivity and battery life, with customers also describing the headphones as portable and useful for gym or daily wear. Those reports align with the listed foldable over-ear design and Bluetooth connection, but do not clarify the conflicting Bluetooth-version details or substantiate a particular battery runtime. The overall rating distribution is strongly weighted toward five-star ratings, though ratings alone do not establish specific performance or explain less-positive experiences.

Frequently asked questions

Are the Qolsa Cool4-Black headphones Bluetooth 5.1 or Bluetooth 6.0?

The listing conflicts: its dedicated Bluetooth version field says 5.1, while a highlight mentions Bluetooth6.0. Confirm the version with the selected listing before buying.

Do these headphones include a wired audio connection?

The details list Cable as built-in media but also say No Jack. The supplied information does not establish how a cable connects, so verify whether a cable is included and usable.

Are they waterproof?

The listing labels their water resistance as Waterproof but gives no rating or usage conditions. Do not assume a particular level of protection from that wording alone.
