Design and features:The Elite 75t has an integrated microphone and volume, music player, and call connect/disconnect controls for paired Bluetooth devices. The right earpiece can be used alone for one ear monitoring of Bluetooth streamed audio and telephone communications, and the earphones have an auto pause feature that automatically stops audio playback when one earphone is taken out of ear and resumes when it is put back in place. This model supports Amazon Alexa, Google Assistant, and Apple Siri digital voice assistants when used with Bluetooth devices that have those features. It is claimed by the manufacturer to be dust and water resistant and comes with three pairs of ear pieces in various sizes, a USB charging cable, and a charging cradle/recharger battery/carrying case that the manufacture claims can be used to recharge the earphone batteries approximately 3 times between its own charges. The free Jabra Sound+ app for Apple and Android mobile devices can be used to provide earphone control customization, ambient sound monitoring adjustment, tone control preset and graphical EQ adjustment, earphones firmware updating, misplaced earphone tracking, and other features.
Sound quality: We found the Elite 75t delivers sound quality that falls in the good range - it reproduces music and voice reasonably well despite the obvious shortcomings in its sound. With the the Jabra Sound+ app equalizer set to flat and Music Presets set to Neutral (as received state of the earphone) the bass (as in bass drums, bass guitars, stand-up bass, etc.) goes deep, but has excessive impact and is very prominent and boomy. The midrange (voices, guitars, horns, etc.) is a somewhat thin, grainy, and etched, and a bit hazy and sibilant. The treble (cymbals, the upper range of violins, etc.) is extended, but somewhat prominent and smeared. The sound also has a good sense of liveliness and is somewhat open--sound-wise it almost seems like you don't have anything plugging up your ears, but it only does a so-so job of recovering room ambience (the sense of the acoustic space in which the audio program that's being listened to was recorded). Mixed character - warm bass with cool midrange and treble. The overall sound can best be summarized as very bassy with a somewhat tinny midrange and treble. The tone settings of the app do have a noticable effect on the sound of these earphones.
Comfort: As typical of in-ear models they produce a sense of pressure in the ear canal opening that might be uncomfortable for some. Users with small earbowls might find that the earphone body feels a bit bulky in their earbowl and that they stick out too far and feel like they may lever out of place and are mostly held in place by the section of the earphone that is inserted in the ear canal, but that they will generally stay in place during casual use. Users with medium and larger sized ear bowls will probably find that this model fits and stays in place even during vigorous head movement.
