Shure SRH1840 Headphones

Design: Just the Basics

The Shure SRH1840 headphones have a minimalist design that still exudes quality and durability. They feature a slim metal frame that curves over the head, with thin padding underneath. The earcups are equipped with outward-facing metal grilles, which allow sound to enter and exit—this is typical for open-back headphones. Inside the earcups, there is plush padding that can be removed and replaced if it becomes worn. Additionally, the cable can also be replaced if necessary. These replaceable components ensure the headphones remain functional for a long time.

Despite the simple build and limited padding on the headband, the headphones are remarkably comfortable to wear for extended periods. This is largely due to their lightweight design, which makes them easy to wear for hours without discomfort. On warmer days, the earcups may become slightly warm, but this is normal and not a significant drawback.

It's important to note that these headphones are designed for studio use rather than portability. The earcups can adjust to fit different head sizes, but they do not fold, making them less convenient for travel. A sturdy hard case is included in the package, but it is quite large and may take up considerable space in a backpack. These headphones are intended for professional use in a studio or for audio enthusiasts who prefer to use them at home.

Internally, the headphones are equipped with 40mm neodymium drivers that can produce a frequency range from 10Hz to 30kHz. With an impedance of 65 ohms, they can be driven effectively by a phone or laptop without the need for a dedicated headphone amplifier. However, using a dedicated DAC (digital-to-analog converter) can enhance the audio experience compared to the built-in audio output of most devices.

The packaging includes a variety of useful accessories. Alongside the headphones and the hard case, users receive two detachable cables, a threaded 3.5mm to one-quarter-inch adapter, and an extra pair of earcups. This comprehensive set of accessories ensures that the headphones come with everything needed for a lifetime of listening.

Sound: A Flat, Natural Presentation

Open-back headphones are not suitable for everyone, especially those new to the concept. It’s important to understand that these headphones allow sound to escape and external noise to enter, making them best suited for quiet environments. The Shure SRH1840s are designed for a neutral, accurate listening experience, and they deliver exactly that.

They offer a wide soundstage that enhances the immersive quality of music, giving instruments more space and clarity. The bass response is deep and warm, while the highs are crisp and well-defined. For example, on "Silent Shout" by The Knife, the sub-bass content is reproduced with a strong, thumping presence. The bass is rich and doesn't overpower the other frequencies, allowing the percussion to remain clear and distinct.

On "Loyalty" by Kendrick Lamar, the bass line is challenging to reproduce, but the SRH1840s manage to capture most of the notes, delivering a subtle rumble that prevents a sense of emptiness. While the bass isn’t as responsive as some higher frequencies, this laid-back approach is not necessarily a negative aspect.

Listening to Bill Callahan’s "Drover" through these headphones highlights the natural and clear sound of the acoustic guitar, which benefits from the wider soundstage. The drums are crisp and the kick drum remains present without becoming distracting.

In orchestral tracks like the opening scene of John Adams’ The Gospel According to the Other Mary, the wide soundstage helps instruments stand out even when playing together. The brass sounds bright and the strings maintain a natural tone, avoiding the muddiness often found in closed-back or less expensive headphones.

For listeners who prioritize accuracy, the SRH1840’s natural sound is a positive trait. However, some audiophiles might find the sound too flat and lacking in color or excitement. Still, for critical listening and studio work, the SRH1840 offers a reliable and precise audio experience.
