The JBL Synchros E10 unboxing results in 3 pair of eartips and a nice carrying case. Everything comes inside the typical JBL packaging, which is fairly small but nicely designed.

Bass & Sub Bass

The JBL Synchros E10 bass has strong mid-bass and deep sub-bass. Expect a style that will fulfill bassy listener’s needs but not as powerful as to become a basshead earphone. Their bass will never fall short while listening any type of music genre.

Applying an EQ, there is a very noticeable extra amount of depth and punch.

Putting the JBL Synchros E10 through out our extreme bass tests, they managed to take up to 45% of a Fiio amplifier maximum power (Fiio E12 Mont Blanc, not A nor DIY edition) resulting in a crazy empowering of bass with mild basshead impact but not even near the Sony MDR-EX650, Beats urBeats, Sony MDR-EX800st / Sony MDR7550, Pioneer SE-CX8.

Mids & Vocals

The JBL Synchros E10 mids have warm mids with noticeable mid-bass bleed that add some congestion to their lower mids. Male vocals sound somewhat alive but get affected by mid-bass bleed making them a bit distant. Higher mids are not forward not too rolled-off and tend to a laid-back tuning and non-harsh sound.

With an EQ male vocals are given much more importance and sound clearer but higher mids can risk to become harshy.

Highs & Treble

The JBL Synchros E10 highs have sufficient brightness for normal listeners but expect a clearly dark tint – regarding detail, they resolve little to none.

This rolled-off style grants them a non-fatiguing sound with only some sporadic sibilance.

An EQ gives an important addition of brightness and some detail.
