First, another BIG props to Barra for starting and coordinating this tour. Second, BIG props to Emil from Lime Ears.
It's a rare privilege indeed to audition finely crafted conduits to deliver hi-fidelity to our ears. In this tour, only three models represented the Lime Ears product line, but at the end of my audition, I came away with Lime Ears house sound. It is very well represented and consistent from the two driver LE2 to the three-driver LE3 SW and its flagship five-driver Aether.

All three are musical and engaging. And while you experience the LE2 warm sound, the dynamics, impact, and extensions are offered in greater magnitude as you experience going up the Lime Ears sonic ladder. What's consistent is the warm, slightly forward and engaging mids. I found the LE3 SW with the bass boost off the most balanced out of the three. However, it was a pleasant surprise to flip up the bass boost when listening to "Nothing But A G' Thing" and other bass heavy tracks that are scarce in my music collection. The boost is well implemented and never bleeds in the mids. But, in all truth, bass-heads need not apply here. When it comes to sub-bass impact, dynamic transducers are king. Same applies to the Aether flagship. When comparing the LE3 SW to the Aether, the former takes everything and increases them in spades, especially with detail retrieval and sound stage depth.
With the Aether, I couldn't help notice from my fallible-prone audible memory some similarities with the Westone ES5 that I use to have. Both warm, slightly thick, dynamic, and enough impact with the Aether's bass switch on - translates to lost in music. I found nothing overly done or overlapping that could take away any musicality or toe-tapping enchantments. The Aether's extension high to ring some sparkle, but never allows sibilence to come into play.
In short, all three models equally represents the Lime Ears "house" sound. The LE2 is a great ciem for vocal and mid lovers. The LE3 SW hit my sweet spot with its tonal balance and with the added benefit of spicing up things with the well implemented bass boost switch. For top tier dynamics , the Aether rightfully takes the flagship cake.
Well that's it - keep the change.
