Below are excerpts from the review:
“The ddHiFi Surface is a well-executed hybrid IEM that prioritises comfort, composure and day-to-day practicality. The 3D-printed shell fits securely and the aluminium faceplate gives a refined finish, while the recessed 0.78 mm 2-pin connectors and bundled BC120S cable round out a thoughtful package. Inside, the single dynamic driver and quad balanced armatures are tied together by a carefully refined crossover, resulting in a smooth, gently warm tuning that places vocals and acoustic timbre front and centre.
On the ear the presentation is clean, controlled and easy to live with. Bass is disciplined rather than dominant, the midrange carries natural presence and treble is crisp without stridency. Imaging is tidy with sensible stage dimensions, and the Surface scales with better sources without punishing everyday streams.
Listeners who want a heavy low end or a brighter, high-energy top may prefer alternatives, but for those seeking a balanced, fatigue-free listen with quality construction and useful accessories, the Surface stands out as a confident entry from ddHiFi in the IEM category.“
