"Possibly the best single BA earphone out there."4.5 starson by xmessenger
Pros: Detail, balanced sound excellent fit and comfort.Blocks out noise without electronic help. Build quality.
Cons: Some have issues with cable and price is too much at full retail. The bass will not be enough for bassheads but is plenty for most.
Summary: The detail of these is very good, as is the imaging although they don't have the largest soundstage. They aren't cold or too analytical for a balanced armature. I've stepped on these without issue. The sound is plain impressive. Very even throughout the frequency range with nice detailed bass thats not at all boomy or loose. You really hear everything in the music. I've had the Shure SE110 which was OK but missing chunks of sound. The Klipsch S4 which were great but compared to these they have a dropped midrange and lack the detailed bass. My V Moda M80s are my regular phones but again lose to these in detail reproduction but they have more bass oomph, the trade off is the bass doesn't present the detail the X5 has. The X5 is a brilliant balanced and detailed yet not cold IEM that is overlooked because it #2 in the line. There are many who have numerous IEM and think these best Shure 535.
