Customer Review Summary
Introduction
The OLLO Audio X1 1.0 2024 is an open-back over-ear headphone model launched in January 2025, retailing at £475. Designed primarily for studio monitoring and mixing, the X1 1.0 aims to combine precise sound reproduction with a distinctive build quality. Featuring American walnut wood ear cups and a stainless steel headband, this dynamic headphone operates at an impedance of 32 Ohms and covers a frequency range from 5 Hz to 22 kHz with a maximum sound pressure level of 101 dB.
Design and Build Quality
The X1 1.0’s construction immediately stands out due to its use of premium materials. The ear cups crafted from American walnut wood provide contribute to acoustic properties by reducing unwanted resonances. The headband is built with stainless steel and overlaid with imitation leather, supporting durability.
Weighing 390 grams, the headphones present a solid yet comfortable weight for extended sessions. The ear pads combine imitation leather and velour, offering a balance between comfort and breathability. The over-ear cups are fixed rigidly to the metal bracket, which impacts the adjustment options, restricting flexibility in fit.
Included accessories are a detachable 2-metre two-sided cable terminating in a 3.5 mm stereo mini-jack, a 6.3 mm stereo jack adapter, a hard case for transport, and a registration card. The inclusion of an adapter and replaceable cable enhances longevity and compatibility with various professional audio equipment.
Sound Quality and Performance
Sonically, the X1 1.0 presents a highly neutral and detailed sound profile with a flat frequency response when used alongside the calibration plug-in USC II software. The headphones achieve clarity across the entire frequency spectrum, from deep lows starting at 5 Hz to highs extending up to 22 kHz, without introducing any harshness or sibilance.
The sound is characterised by an accurate spatial representation, enabling precise mixing decisions. Users have noted the absence of the sharp peak in the high frequencies that can affect other headphones in this price range, resulting in a more forgiving listening experience. The maximum SPL of 101 dB allows the headphones to deliver sufficient volume headroom for critical listening without distortion.
Calibration and Software Support
A distinctive feature of the X1 1.0 is the compatibility with the manufacturer’s calibration plug-in, which supports AU, VST3, and AAX formats on both PC and Mac. This individual calibration ensures the headphone output can be tailored precisely to the user’s ears. However, some users found the calibration steps cumbersome and noted minimal audible differences when applying the software adjustments, suggesting the headphones perform very close to neutral out of the box.
Comfort and Fit
Comfort is a polarising aspect for the OLLO Audio X1 1.0. The fixed position of the ear cups combined with a relatively rigid headband creates pressure on the wearer’s head after extended use, reported by some as becoming uncomfortable following one hour of continuous wear. The headband applies most of its force on the crown with no lateral support or adjustable tension, which may not suit all head shapes or sizes.
On the other hand, the soft velour ear pads are well lauded and provide satisfactory cushioning and breathability for long sessions. Some users with smaller head sizes or less sensitivity to headband pressure reported excellent comfort, appreciating the secure and stable fit during mixing and monitoring.
Durability and Handling
The craftsmanship is of a high standard, but there are warnings regarding the delicate nature of the drivers and connectors. The detachable mini jack input on the ear cups lacks a locking mechanism, warranting careful handling to avoid damaging the connection. The manufacturer issues detailed instructions to prevent applying excessive unilateral pressure on the ear cups, which could compromise the transducers.
The solid wood ear cups and metal headband contribute to robust structural integrity, while the replaceable cable design offers ease of maintenance. The supplied hard case facilitates safe transport, supporting the longevity of the headset.
Conclusion
The OLLO Audio X1 1.0 2024 is a precision tool for professional audio practitioners who prioritise sonic accuracy and build quality. Its natural, flat sound with excellent spatial imaging makes it well-suited for mixing and mastering in a studio environment. The wood and metal construction delivers a premium look and feel, although the headphone’s comfort level may require acclimatisation or be less suitable for those with sensitive heads.
At £475, the X1 1.0 competes favourably with established models, offering a distinctive alternative with an emphasis on honesty in sound reproduction. Potential buyers should take note of fit and comfort considerations prior to purchase. For users willing to handle the cautious maintenance it demands, this headphone delivers a detailed, fatigue-resistant listening experience that translates well from headphones to studio monitors.
