The Synchros E10 has the typical JBL sound signature – well represented mids and highs with an over-load on bass. In terms of performance, it’s got what you would need – clarity, tonal accuracy and decent soundstage. Although, if you compare the E10 to a reference monitor level IEM you’ll find that the lower midrange is a little more enhanced than usual giving them a slightly warm sound signature. Overall, the Synchros is worth a look but maybe not your money.

In terms of features, it hits the right spots as well with its flat, tangle free cable and a see-through box that doubles as a carry case. But how does it hold up against the competition? Let's take the similarly named and priced SoundMagic E10M as a reference. Compared to it, the Synchros E10 falls slightly behind in terms of pure aural performance. The SoundMagic is a superior albeit more delicate headphone and hence there is a trade off. At the same time the Synchros doesn’t come with spare ear tips which was a bit of a downer.
Overall though, The JBL Synchros E10 makes for an almost perfect substitute, hence we'd suggest you try it out before you buy it.
