Design and features:The Rewind Wireless Retro has an integrated microphone and music player and call connect/disconnect controls for paired Bluetooth devices. It also has three switchable EQ modes that change the tonal balance of the headphones, and supports Apple Siri and Google Assistant voice commands when Bluetooth paired to devices that have those capabilities. This model comes with two pairs of ear pads in various colors and a USB charging cable. The free JLab Audio app provides various signals that are intended to "burn-in" audio devices, but otherwise seems to be a shopping link to other JLab products.
Sound quality:We found the Rewind Wireless Retro delivers sound quality that falls in the Fair range, meaning that it has sonic shortcomings that leave a lot to be desired when listening to music but don't rule it out for dialog and communication. The overall sound can best be summarized as thin and nasal. In the Signature EQ mode the bass (as in bass drums, bass guitars, stand-up bass, etc.) is a bit subdued, has so-so impact, and doesn't go deep. The midrange (voices, guitars, horns, etc.) is thin, nasal, hazy and somewhat grainy. The treble (cymbals, the upper range of violins, etc.) is extended, but is prominent, smeared (sounds that should have a delicate shimmer sound blurred) and overbearing with some program material. While the sound has a good sense of liveliness and is somewhat open (sound-wise it almost seems like you don't have anything covering your ears) this model doesn't do a good job of recovering the room ambience of a recording (the sense of the acoustic space in which the audio program that's being listened to was recorded). The EQ settings do have a noticeable effect on the sound - compared to the Signature setting the Bass Boost setting increases the bass impact but makes it a bit prominent and boomy, while the Balanced setting makes the bass more subdued.
Comfort and Fit:We found that these headphones produce a sense of light pressure on the ears.
The earcups don't offer a lot of top-to-bottom and front-to-back swivel range and some may feel that the ear pads sit awkwardly on the ears (they may press harder on the bottom than the top and/or press more on the front than the back).
As typical of on-ear models the ear pads might feel hot after prolonged use.
Small
Users with smaller heads might find that the headphones feel unstable and shift forward a bit when they lean far forward.
