Natural-Sounding Headphone Setups — Pursuing a Lifelike Soundstage

What Is “Natural Sound”?

Natural sound means faithfully reproducing what was recorded without emphasizing any particular frequency range. It’s often called “flat,” but it’s not quite the same as measurement-flat. What matters is that it sounds natural when factoring in human hearing perception.

The ambience of a live venue, the reverb of a studio, the distance of a vocalist — a natural setup reproduces all of these as they are.

What Makes a Headphone Sound Natural

Open-Back Design

For a natural soundstage, open-back headphones have a clear advantage. Closed-back designs trap sound around the ear, intensifying the “inside-the-head” localization effect. Open-backs let air and sound escape, producing a soundstage closer to what you’d hear from speakers.

Moderate Impedance

High-impedance headphones tend to draw out the best from amplifiers while maintaining a low noise floor. Many natural-sounding headphones fall in the 250–600 Ω range.

Low Driver Distortion

Drivers with lightweight, rigid diaphragms offer excellent transient response, delivering natural attack and decay characteristics.

Recommended Headphones

Sennheiser HD600 ($300)

The quintessential natural-sounding headphone. Despite being over 25 years old, it’s still used as a reference. At 300 Ω, the amp’s character comes through directly. Midrange reproduction is particularly impressive — vocals and acoustic instruments sound strikingly lifelike.

Sennheiser HD650 ($350)

A sibling to the HD600, tuned slightly warmer. Bass has a touch more body, and long-session comfort exceeds the HD600. If you want “natural but with a hint of warmth,” the HD650 is the one.

beyerdynamic DT 1990 Pro ($300)

A semi-open monitor headphone. Treble extension is superb — cymbals and hi-hats are rendered with exceptional realism. Two sets of ear pads (Analytical and Balanced) let you fine-tune the tonal balance.

AKG K712 Pro ($250)

An open-back with a notably wide soundstage. Orchestral and live recordings reveal instrument placement with pinpoint accuracy. At 62 Ω, it’s relatively easy to drive.

Choosing a DAC

For natural setups, minimal coloration from the DAC is ideal.

RME ADI-2 DAC FS ($1,300)

Monitor-grade accuracy that extracts every detail from the source. The built-in parametric EQ allows fine-tuning for room acoustics or headphone characteristics. The crossfeed function reduces the in-head localization effect — a welcome feature for those pursuing natural sound.

Topping DX5 ($450)

The ES9068AS chip is close to flat with a subtle warmth. This slight touch of smoothness naturally softens digital edges, contributing to a perceptually natural presentation. The pairing with the HD600 is a tried-and-true classic.

Schiit Modi Multibit ($250)

The multibit architecture takes a fundamentally different approach from delta-sigma, producing a uniquely natural sonic texture. It has a strong reputation for reproducing instrument timbre and hall ambience.

Three Recommended Setups

Setup 1: Pure Natural (~$1,600)

• DAC: RME ADI-2 DAC FS ($1,300)
• Headphone: Sennheiser HD600 ($300)

A reference DAC paired with a reference headphone — the textbook combination. Zero coloration, where source quality determines everything. Ideal for classical, jazz, and acoustic music.

Setup 2: Warm Natural (~$800)

• DAC/Amp: Topping DX5 ($450)
• Headphone: Sennheiser HD650 ($350)

A setup with a subtle warmth within a neutral framework. Excels with vocal-driven tracks and R&B. Outstanding comfort for extended listening sessions.

Setup 3: Wide Stage (~$550)

• DAC: Schiit Modi Multibit ($250)
• Amp: Schiit Magni+ ($100)
• Headphone: AKG K712 Pro ($250)

The honest sound of the Schiit stack combined with the K712 Pro’s expansive soundstage — orchestral and live recordings unfold right before you.

Making Use of Crossfeed

Crossfeed improves the in-head localization that is a weakness of headphone listening. By mixing a small amount of the left signal into the right channel and vice versa, it recreates a soundstage closer to speaker listening. It’s available on the RME ADI-2 DAC FS and iFi products, among others. If you’re serious about natural sound, it’s a feature well worth trying.

Conclusion

For a natural-sounding headphone setup, the HD600 + Topping DX5 offers the best balance of value and performance. For the ultimate experience, go with the RME ADI-2 DAC FS + HD600. An open-back headphone paired with a low-coloration DAC is the shortest path to a truly natural music experience.
