Customer Review Summary
Introduction to Avantone Planar the II Red
The Avantone Planar the II Red is a planar magnetic headphone model released in October 2023. With an open-back over-ear design, it targets users seeking high-fidelity audio reproduction combined with comfort and durability. Priced at £381, this model is equipped with notable features such as a 21-micron PET diaphragm and a wide frequency range from 30 Hz to 30,000 Hz. It also includes a detachable cable system and comes with an adapter and carrying bag, appealing to audiophiles and professionals alike.
Design and Build Quality
The Avantone Planar the II Red’s construction emphasises robust materials, incorporating aluminium and steel components complemented by soft velvet ear pads. The headphones weigh 510 grams, which is significant but well managed by a wide headband that distributes pressure evenly, ensuring comfort during prolonged listening sessions.
The open circumaural design facilitates airflow and reduces ear fatigue, characteristics valuable for long-term wear. An added practical feature is the ability to connect the cable on either side, enhancing user convenience. The system impedance is rated at 32 Ohms with a high sensitivity of 104 dB/mW, making the headphones compatible with various audio sources, including those with modest power outputs. The inclusion of a replaceable cable and interchangeable ear pads further underscores Avantone’s focus on longevity and user customisation.
Sound Quality and Performance
The most significant aspect of the Avantone Planar the II Red lies in its audio reproduction. The planar magnetic transducer, sized at 70 x 95 mm, delivers an extensive frequency response that covers deep bass and crystal-clear trebles. The headphones exhibit an excellent dynamic range with a maximum sound pressure level exceeding 130 dB, which contributes to the accurate and detailed presentation of sound.
Users report a very natural, uncoloured sound signature with excellent instrument separation and precise localisation, although with a notably narrow soundstage typical of planar magnetic designs. The sonic character avoids harsh sibilance and loudness spikes. This tonal balance makes the headphones particularly suitable for critical listening such as mixing and mastering, where neutrality and clarity are paramount.
Strengths in Audio Detailing
- Detailed and extended frequency response, notably strong in the bass and ultra-low frequencies
- Excellent impulse response providing clarity in transient-heavy passages
- Sound remains musical and engaging rather than clinical, maintaining listener enjoyment
- High sensitivity aids in driving the headphones effectively without requiring specialist amplification, though enhanced amplification improves the experience
Potential Limitations
- Some users note a congested midrange, described as slightly forward, which affects the timbral balance for certain tastes
- Soundstage lacks depth and width compared to some open-back dynamic headphones or studio monitors
- Sub-bass reproduction may not satisfy users seeking a highly textured or powerful low-end experience
- Minor build quality inconsistencies reported in some units requiring adjustment or exchange
Comfort and Practical Use
The Planar the II Red headphone design excels in long listening sessions due to the generous padding and adjustable headband firmness. Although weighty, the distribution moderates fatigue. The open-back construction offers a spacious feel but requires a quiet environment to fully appreciate the details without external noise intrusion.
The provision of a 1.5-meter cable with a 3.5 mm stereo jack, plus a 6.3 mm adapter, suits a range of audio equipment. The cable’s robust shielding reduces microphonic noise, a welcomed feature in a planar headphone that can otherwise be sensitive to cable handling.
Conclusion
The Avantone Planar the II Red delivers compelling technical specifications and impressive sound fidelity characteristic of planar magnetic headphones. Its strength lies in detailed and natural sound reproduction that remains engaging across various music genres. The build quality and comfort support extended use, although potential buyers need to be aware of a somewhat congested midrange and limited soundstage. This product suits those prioritising analytical listening balanced with musicality, particularly in controlled environments with quality source equipment.
Avantone’s Planar the II Red is a solid contender at its price point, worth consideration by audio professionals and discerning enthusiasts willing to invest in a nuanced and robust open-back headphone.
