Excellent sound at reasonable cost
on June 28, 2014
Update: Exactly one year and three days later, the cable broke down near the plug. For this reason, I take one star down for durability in an otherwise excellent earphone.
Best earphones I ever had. Excellent detail and definition. Good bass, but not too much; it might disappoint some bass-heads that love hip-hop and Beats by Dr. Dre but perfect for those who want a deep, natural bass. The sound is great right out of the box, but it gets significantly better with time. So if you find them a little harsh at first, it is normal; after the break-in period they get better.
Two caveats for Samsung Galaxy S4 owners. First, the volume buttons will not work, they are intended for iPhones, iPads, iPods, etc. The one important button, however, works fine. Second caveat, this earphones have a relatively low impedance. This is usually good, but for some reason the Samsung Galaxy S4 is incapable of delivering the high current needed at high volumes, especially if there is a lot of bass in the music. As other people reported, the S4 will "pop" and it sounds horrible when it happens.
Fortunately, in my case the remedy was very simple. I flashed my phone from Android 4.2 to 4.4 using the update provided by T-Mobile. This means I did not have to hack or "root" the phone, I just used what T-Mobile recommends and offers, and that fixed the problem. Anyway, this is more of an S4 issue than an Ultimate Ears issue.
Compared to other phones, these are relatively brilliant, much more than the Sony MDR-XD200 I also own. I expected the Ultimate Ears to give me more ear fatigue for being so brilliant, but it has not happened so far after long hours of listening. I can give these UE 600 the highest grade, especially at this price point.
