FiiO FT1 Pro Headphones

The FiiO FT1 Pro Open-Back Headphones represent the next step in FiiO’s FT series, delivering unparalleled sound quality with a combination of planar magnetic technology and open-back design. Tailored for audiophiles, these headphones merge cutting-edge engineering with elegant ergonomics, creating a listening experience that is both immersive and comfortable. Whether you're a casual listener or a seasoned enthusiast, the FT1 Pro promises a pristine and expansive soundstage. Featuring FiiO's second-generation planar driver technology, the FT1 Pro is designed to outperform in its price category, making it an excellent choice for critical listening and home audio setups. FiiO’s Revolutionary Planar Magnetic Driver The FT1 Pro is powered by a proprietary 95x86mm planar magnetic driver, designed entirely in-house by FiiO. Unlike off-the-shelf planar drivers, this innovative system integrates a 1μm ultra-thin diaphragm with a patented dual-coating of sapphire and aluminum. The result? Exceptional clarity, responsiveness, and a frequency range extending up to 40kHz. This unique construction enables the FT1 Pro to reproduce rich bass, transparent mids, and detailed highs with precision and depth. Despite its advanced driver system, the FT1 Pro maintains a lightweight build of just 374g, ensuring comfort even during long listening sessions. Sapphire-Aluminum Dual Coating for Enhanced Fidelity To achieve class-leading performance, FiiO has employed a patented dual-coating system on the planar diaphragm. The aluminum coating enhances conductivity, improving the dynamic response and reducing impedance, while the sapphire layer increases rigidity and treble accuracy. This thoughtful pairing of materials provides a balanced yet highly detailed sound signature, making every note and nuance in your music come alive. Listeners will appreciate the FT1 Pro’s ability to deliver a wide dynamic range, making it suitable for a variety of music genres, from classical and jazz to electronic and rock. Open-Back Design for an Expansive Soundstage The FT1 Pro’s open-back design ensures a natural and spacious listening experience. By allowing sound waves to travel freely through the metal grid earcup covers, the headphones reduce unwanted resonance and reflections, creating an authentic and immersive soundstage. This makes the FT1 Pro an excellent choice for critical listening in quieter environments, as it delivers an airy and open presentation that closed-back headphones cannot replicate. Perfect for at-home use, the FT1 Pro provides an expansive and detailed auditory experience that rivals headphones at higher price points. Ergonomic Comfort Meets Durability The adaptive 3-axis headband of the FT1 Pro adjusts seamlessly to different head sizes, ensuring a snug and secure fit. The lightweight steel rails enhance durability without adding unnecessary weight, while the lychee leather headband padding offers a soft and luxurious feel. The breathable fabric ear pads further enhance comfort, efficiently dissipating heat and providing a secure fit for long listening sessions. With its sophisticated design and precision engineering, the FT1 Pro strikes the perfect balance between comfort, durability, and style. Versatile Connectivity and Accessories The FT1 Pro includes two high-quality detachable cables to suit your audio setup: a 3.5mm single-ended cable and a 4.4mm balanced cable, both constructed from silver-plated oxygen-free copper for optimal signal transmission. A 3.5mm to 6.3mm adapter is also provided, making the headphones compatible with a wide range of devices, from portable audio players to desktop DAC/amps. A premium softshell storage case is included for convenient transport and protection, making the FT1 Pro an excellent choice for both home and on-the-go listening. Technical Specifications Feature Specification Driver Planar Magnetic Impedance 20Ω Sensitivity 112dB/Vrms (@1kHz) / 95dB/mW (@1kHz) Frequency Response 7Hz-40kHz Weight 374g (without cable) Cable Material Silver-plated oxygen-free copper Cable Length 150cm What’s Included: FiiO FT1 Pro Headphones 4.4mm Balanced Cable 3.5mm Single-Ended Cable 3.5mm to 6.3mm Adapter Storage Case Quick Start Guide 1-Year Warranty With its sophisticated planar technology, premium materials, and ergonomic design, the FiiO FT1 Pro is perfect for audiophiles who demand uncompromised sound quality and comfort.

There’s also an HDMI (eARC) connection for a high-quality link up with your TV, and a dedicated output on each of the two speakers for the addition of one or two KEF subwoofers.

Combining all KEF’s key technologies, LS60 Wireless delivers superlative acoustic performance. Single source. Coherent sound At the heart of LS60 Wireless sits the Single Apparent Source technology adapted from our flagship Blade loudspeaker. It aims to achieve the acoustic ideal of a point source, where low, mid and high frequencies radiate from one point. It is what makes LS60 Wireless incredibly coherent, with more precise and clear sound across the whole bandwidth. Sit anywhere, hear every detail Uni-Q technology is the building block of KEF signature sound. Designed to perform at its best in LS60 Wireless, the remarkable 12th generation Uni-Q driver array acts as a single point source enlarges the ‘sweet spot’ and disperses sound more evenly, allowing everyone sitting at different spots in the room to experience the same natural, detailed sound. Absorb 99% of the unwanted sound The LS60 Wireless benefits from our latest acoustic innovation: Metamaterial Absorption Technology (MAT™). MAT™ is a highly complex maze-like structure that absorbs 99% of the unwanted sound from the rear of the driver, eliminating the resulting distortion and providing purer, more natural sound. Maximises bass, minimises space LS60 Wireless features the revolutionary Uni-Core technology that redefines size versus performance. Two pairs of Uni-Core bass drivers are mounted back-to-back in a force-cancelling arrangement, so cabinet vibration is practically eliminated. Together with P-Flex driver surround and Smart Distortion Control Technology, the bass is balanced, detailed, deep and powerful. Perfectly controlled Music Integrity Engine is the brain behind LS60 Wireless. It is precisely tuned to allow the Single Apparent Source configuration and the Uni-Core drivers to work in perfect harmony, elevating the performance of each. Its low-frequency phase correction feature delivers pinpoint timing exactly as if you were listening to the original sound. Audiophile-grade power The LS60 Wireless also has power in abundance, with a highly optimized mixture of bespoke Class AB and Class D amplification delivering a combined 1400 Watts of audiophile-grade power, with amplifiers dedicated to high, medium and low frequencies within each speaker. High-Fidelity sound LS60 Wireless aims to bring high-fidelity sound to more people in their homes. With the combination of all our key technologies, LS60 Wireless delivers high-fidelity sound up to 24bit/384kHz. Impossibly slim LS60 Wireless defies the limits of audio performance with its iconic slim structure. The extremely slim profile is only possible with all the advanced technologies contained within. LS60 Wireless is truly a speaker system that looks as good as it sounds. Attention to every detail Every aspect of LS60 Wireless has been considered for acoustic benefits and from a design perspective. Designed for performance As a high-performance all-in-one speaker system, every aspect of the LS60 Wireless design is a case of form following function. The well-considered design of the back panel and plinth incorporates a cooling mechanism for sufficient air circulation, allowing LS60 Wireless to perform at its best without overheating. Finished to perfection The sleek speaker cabinets are finished in three matte finishes: Titanium Grey, Mineral White and Royal Blue, all of which feature tone-matched drive units.

DMS Project Omega Headphones

The DMS Project Omega Headphones are a heartfelt tribute to the world of audio. Built from the ground up from DMS over the last couple of years, this is a project that he has poured his heart and soul into. Crafted with a keen focus on durability and sound quality, these headphones feature a unique hollow cup structure made via nylon sintering for lightweight comfort and a meticulously selected driver for consistent, natural low-end elevation. Emphasizing function over form, the design may not appeal to everyone, but it's a deliberate choice to prioritize auditory experience over aesthetics. The DMS Project Omega is a limited-run headphone with production running for just a year. After that, the design will be open-sourced to the community. This isn't a collaboration product. This is a product built from the ground up through passion, blood sweat and tears from DMS. DMS isn't just looking for profit but is hoping that over the year he gains a deeper understanding of the industry and in turn, enhances his knowledge as a reviewer.
