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) .

E+- Tonally jarring or fatiguing. Frequency clashes (e.g., piercing treble, bloated bass) make extended listening unpleasant. Poor genre adaptation.
Average Technical Grade
E+- Noticeably blurred or congested. Struggles with basic instrument separation; details are lost in simple tracks. Feels "flat" and one-dimensional.
