I usually don't like things that aren't all rounders but this might be the exception. Bass is incredible - best in class - great texture, fantastic physicality. Treble response is great too - pretty resolving. There is a noticeable recession in the upper mids, giving these a fairly U/V shaped sound signature - violins, for example, lack a bit of brightness/bite that I would hope for. But unlike other V-shaped IEMs, the mids aren't offensive. Incredibly fun to listen to. Probably the best single DD available. EQ highly recommended. Previously Owned

Excelllent bass - simply excellent. Midrange could use some work, as could the generally average imaging chops. Precogvision Youtube Channel

Instrument separation is good, and is a nice darkness, but can be silbilant. Jaytiss Youtube Channel

Clean, neutral, and clear vocals. Reminds me of a cleaner Volume S or slightly better OG Oracle, but very expensive, maybe if you can find one around $1000 since it's more of a sidegrade to RSV, Mystic 8, and Arcanis vocal wise. If you want clean vocals Monarch MK2 does the same thing but for $700 less. Jays Audio Youtube Channel

The Elysian Apostle delivers a V-shaped signature with a powerful, sub-bass-focused low end that offers substantial rumble and physicality, though some listeners might find it occasionally overwhelming or lacking in tight control. Its dual electrostatic drivers provide crisp, extended treble with good air and minimal harshness, while the midrange remains clear and natural despite slight recession, particularly excelling with vocal clarity and emotional delivery.
Comfort is mixed due to the large nozzle diameter, which demands extensive tip-rolling for a secure fit, though the lightweight aluminum shells are ergonomic for extended wear once settled. The Pentaconn ear connectors offer stability but limit third-party cable options, and the included accessories like the Divinus Velvet tips are functional but basic for the price tier.
Positioned as an "Annihilator Junior", the Apostle captures much of Elysian’s energetic house sound at a lower cost, offering strong technical performance like wide staging and solid resolution. However, its bass dominance and fit quirks make it less versatile across genres, appealing mainly to those seeking a fun, dynamic listen rather than strict neutrality.
