The Chord Electronics Mojo 2 & Sennheiser HD 660 S Headphones bundle is great for taking high-quality audio with you wherever you go.
The Chord Electronics Mojo 2 Portable DAC & Headphone Amplifier is the long-awaited sequel to the original Mojo that offers high-res audio on the go. Chord Electronics has taken the original design of the Mojo and enhanced it for the modern audiophile making it better than ever. Proprietary technology designed in the UK has gone into Mojo 2 to make it the most advanced portable DAC available on the market. Improved battery life and new USB-C connection options are just the beginning.
Mojo 2 features the world's first lossless DSP with advanced EQ controls, so the main contender for the best portable DAC and headphone amp just got better. A new control system makes operation intuitive for new adopters of Mojo, yet familiar for those who already gain the benefits of hi-res audio on the go with the original Mojo. Full compatibility is also supported with the Chord Poly that allows you to go wireless with your audio. Unrivalled performance, class-leading sound and peerless build quality make this a must-have for all audiophiles and music lovers.
The new HD 660 S lets you enjoy sophisticated audiophile sound in even more listening situations. The successor of the legendary HD 650 excels with the improved performance of its new transducer design. Thanks to its lower impedance, it delivers reference-class sound also when connected to hi-res mobile players, thus offering much greater versatility. The HD 660 S is an elegantly designed piece of high-quality engineering that indulges the demanding listener with aural precision and great wearing comfort.

"Mojo 2 takes DACs at this price point to a whole new level"
"Familiar in form but next-level everywhere else, the Mojo 2 is the The Godfather Part II of DAC sequels"
Designed in the UK by Chord Electronic's world-class engineers, the Mojo 2 is the most advanced portable DAC available today. The bestselling, original Mojo is highly coveted by audiophiles as it offered an opportunity to take your hi-res sound on the go so Mojo 2 has been built to impress. It features a world-first in the form of a lossless UHD DSP which has a 104-bit custom DSP core running at 705/768kHz which greatly improves the quality offered by the original model whilst also allowing for greater EQ of your audio, with 18 steps of adjustment per frequency band so you can shape your audio the way you want in unbelievable quality.
One of the biggest calls from fans of the original DAC was for an update with USB-C compatibility, well Chord Electronics has delivered. On top of the original connections offered with the optical, coaxial micro USB and headphone outputs, the Mojo 2 now features a USB-C connection but what does this mean for you? Well, now you have the opportunity to connect up to modern devices such as Apple Macbooks and Android smartphones dongle-free!
As technology moves on, more and more companies opt for wireless technology and with that, sound quality over wireless gets better making it a viable option for modern audiophiles. Chord Electronics has the perfect product for enhancing your experience with the option of taking Mojo 2 wireless. Being Poly compatible means those who already have the original Mojo with Poly and want to go for the improved performance can dive straight in and those who are new to Mojo can open their doors to hi-fi wireless with the perfect accessory.
Made for the demanding listener, the HD 660 S surpasses the exceptional performance of its predecessor, the legendary HD 650. With a crisp bass, excellent mid-frequency response, and a gentle, pleasantly natural treble, the HD 660 S has an expressiveness that immerses you in every emotion and nuance of music. Still, it always stays exceptionally accurate and transparent.
The HD 660 S features a new transducer design developed by Sennheiser. This results in improved control of the diaphragm movements thanks to a specially manufactured precision stainless steel fabric, which is adapted to the contour of the diaphragm. Extremely light aluminum voice coils ensure the highest impulse fidelity. The transducers are carefully selected and paired by hand to ensure consistently narrow (±1 dB) tolerances.
The HD 660 S has been created to enjoy music in supreme quality and from many different audio sources. Thanks to its low impedance it also offers reference-class fidelity with hi-res mobile players. Naturally, the HD 660 S reveals its full potential when it is connected to the balanced outputs of a dedicated headphone amplifier such as the HDV 820 or to the balanced output of a mobile digital audio player. Accordingly, it comes with a choice of cables for just about any occasion. All cables are made of highly conductive OFC copper, featuring very low handling noise and sturdy para-aramid reinforcement.
