Con Requires a headphone amp for optimal sound
Plugging these directly to your computer or phone will most likely result in audio that is lacking in volume or may sound too thin. To get the best listening experience, you will need to run these with a capable headphone amp.
Con Bass and recessed highs can make the sound come off as muddy for some
The bass is quite powerful that it can creep up to the lower mids. Combined with the rolled off highs, this can result in a sound that may be muddy or quite less-detailed for some. If you like lot of treble or sparkle in your music then there are other in-ear headphones that have better reproduction of the highs.
