Do these headphones have noise cancelling?

No. They are passive over-ear headphones, so the padded earcups block some sound but engine and crowd noise still comes through. For real noise cancelling you need a model that lists ANC.

They pair over standard Bluetooth, so they work with phones, tablets and laptops without a dongle. There is no wired-only mode advertised, so plan on charging them for listening.

Are they good for long commutes?

The earcups and headband use soft ergonomic padding, which is the main selling point for all-day wear. The bass-heavy tuning suits commutes, but without ANC you will hear more of the train or street than with pricier rivals.

How do they compare with JBL or Soundcore over-ears?

Those rivals typically add app EQ, longer rated battery life and sometimes ANC at the entry level. The Polaroid leans on comfort padding and a simple wireless setup instead of extra features.

What comes in the box?

The headphones themselves; a charging cable is standard for wireless models of this type. Check the box contents before buying if a carry case matters to you.
