It's a little bright. Jaytiss Youtube Channel

CLEAR with LOTS of detail. Nice sub-bass rumble with no mid-bass bleed. Treble is super extended as well as high-mids. Female vocals sound lively and sings, but can be too much at high volume and overly thin. Great imaging and separation. Artificially boosted treble, too sharp. Jays Audio Youtube Channel
6.2
Reviewer Score
Great bass dynamics and well done mid-range. Treble extension is great but a hair too elevated.

Incredibly well tuned IEM that sounds very natural across all frequencies. Nothing inoffensive with good technical chops. Stage is not vast - but it is natural and has depth. Bass is full but it is very much on the pillowy side. Mids are natural sounding and clear. Vocals are lush. Instruments sound as they should - timbre is very, very natural - this dethrones Supernova as timbre king IMO. Imaging is pretty decent with decent separation. Decently detailed sounding. Incredibly pleasant to listen to and never fatiguing. Very smooth sound overall. Held back by markedly blunted transients and lack of dynamics that can sometimes make things sound softer than I like as far as attack/incisiveness goes. A great all-rounder. Previously Owned

A "plain water" type sound signature with a bass boost. Great tuning, neutral with bass boost, smooth, safe, and balanced. Could use more detail, incisiveness, and excitement.Gizaudio Axel original ranking

Bass layering, treble detail are excellent; midrange leans neutral and focuses on clarity over musicality It is not for people who seek addictive midrange or musical presentation

New unit is better tuned/balanced, smooth, good all-rounder, and sounds like adjusted diffusefield. Jays Audio Youtube Channel

Well-tuned and great techs at this price point. Lacks dynamics and the mids are a little lean. Otherwise a great all-rounder.

Very bouncy bass but midrange sounds sucked out and has some oddity. Original sounds more coherent even if less exciting/detailed. Precogvision Youtube Channel

The Hisenior Mega5-EST is a tribrid with a 5-driver array—1DD+2BA+2EST—using a four-way network and triple bores; published specs list ~25 Ω impedance and ~105 dB sensitivity, making it easy to drive from portable sources. Street pricing for the current universal “7th Anniversary” version sits around $549 USD. Source: driver/config & specs (Hisenior) and pricing (HiFiGo) .
Tonally it leans neutral with a sub-bass lift, with a relatively relaxed upper-mid/low-treble region that favors smoothness over bite; ESTs add air without excessive sharpness. Measurements and listening notes describe a calm take versus Harman with noticeable sub-bass emphasis, plus an 11–12 kHz sparkle that keeps things from sounding too soft. References: tuning commentary and FR behavior (Headphones.com) , “calm vs Harman” with sub-bass note (Boizoff) , and FR graph (Squiglink) .
Technicalities are solid but not class-leading for the price: staging and imaging are tidy, separation is clean, while micro-detail and incisiveness are more “easy-listening” than analytical. Reviewers highlight good layering and coherency yet note that resolution “edge definition” and excitement could be higher at this tier. Sources: technical impressions (Headphones.com) and general performance notes (Headfonia) .
