Next, we got the most important factor, sound quality. Now, before we go in further. There is no active noise-cancelling feature on any of these earbuds, only passive noise isolation the Jabra’s and Jaybird’s. The Powerbeats Pro however, do rely on the fit to let in external ambient surrounding sounds. For those who exercise on the street, this may be an advantage so that you can always stay aware of high-volume traffic. But in recent years, technology has caught up. The Jabra’s have HearThrough+ which lets in your environmental sounds through its microphones and it seems to work as naturally as it could be. You can even alter the amount to let in via the Jabra Connect+ App, available of download in the App & Play Store. For now, we will stay focus on the passive noise isolation and talk about overall app experience in the later part of this review. Now, the Jaybirds are disappointing, not for the fact that the noise isolation is bad but because they don’t have such feature to begin with. They seal the world out really well but for those who want to look out for themselves in traffic. They don’t have such a feature. As with all sports earbuds, there is definitely a bias on the bass response straight out of the box. Now, for bass heads looking to blow their eardrums with bass, the Jaybirds are the way to go. The bass is really deep, tight and punchy. It also resonates and lingers in the song. The mids are clear and the bass does not bleed into the mids. However, the mids are not as pronounced and forward as they should be. The highs are decent and did not really stand out or shine much in part due to the bass. But not to worry, the Jaybird’s sound signature is also customizable with the Jaybird App. Next, the Powerbeats Pro are also as bass heavy but they managed to maintain a significant amount of clarity in the rest of the frequency response. The Beats bass is deep and tight but it is fast and does not resonate as much. This is a good thing since the mids sound forward and loud, being careful not to take away from the surround and soundstage. The highs are bright and clear with vocals being in the forefront. Distinct left and right channel could be heard as well. However, with the Beats, you do lose the ability to tune your sound signature to your liking since there is a lack of a built-in equalizer in the Beats app. Going third party is always an option if you really want to. Lastly, we have the Elite Active 75t which does not have a sound quality as great as the Beats. In term of bass, it falls in the middle of the Jaybirds and the Beats. It resonates but it did not manage to keep its clarity and tend to bleed into the mids. Out-of-the-box, it can be really distracting especially when the bass resonates too much and becomes muddy and boomy. The highs sound decently bright and filled with plenty of details. The mids do sound very crisp but sound tuning is definitely needed to help the improve its clarity. You may do all of that in the Jabra Connect+ App as mentioned above. Moving on to the call quality, let’s look at the Jabra’s first because as always, Jabra did it again. They blew the rest out of the water with its superior call quality, leaving only your voice audible to the caller on the other hand. The Powerbeats Pro are second in line but they do let in a small amount of environmental noise but my voice is still always clear. Last in line is the Jaybird Vista with its muffled down voice capture that really isn’t worth using even if you need to answer a quick call.
