Beautiful styling matched to a beautiful sound the EarAcoustic Audio SPA Custom Tuning 

Discover the EarAcoustic Audio SPA Custom Tuning at Eden Audio – a premium single-dynamic-driver IEM designed for music lovers who want a detailed, natural and engaging listening experience.

The SPA Custom Tuning features an advanced 11.4mm dual-magnet, dual-cavity Tesla dynamic driver, combining a titanium dome with a double-sided deposited silicon-crystal surround. This sophisticated driver design is engineered to deliver excellent control, resolution and dynamic performance across a wide range of music.

Its carefully developed tuning aims to balance detail, musicality and long-term listening comfort. The presentation combines a controlled, extended bass response with natural and articulate vocals, clear midrange detail and an energetic but refined treble. An independent 2026 review praised the SPA Custom Tuning for its balance, transparency, detail retrieval, dynamics, separation and spacious imaging, describing it as an outstanding single-dynamic-driver IEM in its price category.

The dual-cavity acoustic design helps create a spacious, well-layered presentation, while the lightweight aviation-aluminium construction provides a premium feel and secure, semi-custom-style fit. The result is an IEM that is equally suited to relaxed home listening, portable hi-fi and critical music listening.

The SPA Custom Tuning is supplied with a high-quality 4.4mm balanced + 3.5mm 2-in-1 Litz coaxial cable, incorporating silver-plated OFC, silver-plated single-crystal copper and gold-silver mixed-braid conductors. The 0.78mm detachable connection also allows the cable to be replaced or upgraded.

With 25Ω impedance, 111dB sensitivity and a claimed 5Hz–40kHz frequency response, the SPA Custom Tuning is easy to pair with a wide range of portable audio sources while offering the resolution and performance expected from a serious hi-fi in-ear monitor.

Whether you're listening to rock, pop, jazz, classical music or acoustic recordings, the EarAcoustic Audio SPA Custom Tuning delivers a detailed, dynamic and spacious presentation designed to let you get closer to your favourite music.
