Youtube Video Summary
STA Pro keeps the dual dynamic recipe but swaps to 10 mm + 6 mm composite diaphragms instead of the Pro Max's LCP and titanium-plated combo. Build is similarly solid—arguably flashier on the faceplate—yet the driver change shifts the character in ways that don't mirror the Max.
While the bass shelf remains, the Pro adds more upper mids and a touch more treble, pulling focus from the low end and dulling the TFZ-style, big-bass fun that made the Max engaging. The attempt to "poke in" extra presence for detail doesn't convert into true clarity; the balance turns brighter and less relaxed.
Technicalities trail the Max: less resolution, less perceived detail, and it doesn't volume scale the same way, coming across as a more affordable, less refined variant. For this line, the smarter buy remains the STA Pro Max with the LCP + titanium drivers; the base STA Pro simply doesn't reach the same level.

Reviewer Score
The EarAcoustic STA Pro Max is a dual-dynamic IEM using a 10 mm LCP diaphragm paired with a 6 mm titanium-plated dynamic driver (2DD). Retail listings also show basic specs of ~110 dB sensitivity, 30 Ω impedance and a stated 10–30 kHz range, placing it in the easy-to-drive, budget category; Linsoul currently lists the Max variant at ~$79.90. A broader product overview from HiFiGo confirms the STA series’ 2DD (10 mm+6 mm) architecture and differentiates models by diaphragm materials, with the Max positioned as the LCP/titanium option.
Community impressions characterize the STA Pro Max as a bassy, V-shaped tuning with a mid-bass-dominant profile and generally lush/smooth mids, trading ultimate neutrality for warmth and fun. These notes align with reports that it delivers thicker note weight rather than maximum treble air, which suits pop and hip-hop more than critical, mid-centric listening.
Technicalities are serviceable for the price: dynamics have some punch from the mid-bass lift, but detail retrieval and stage/imaging are average and can feel compact on busy mixes. On the upside, the 30 Ω/110 dB spec makes it straightforward to drive from a phone dongle, and the 2-pin connection eases cable rolling. Overall, at ~<$100 it offers a warm, bass-forward presentation that prioritizes musical weight over forensic resolution; value is solid, but it doesn’t challenge class leaders on technical performance.
