A classic evolved: Sennheiser's HD650 rolled out six years after its predecessor, the HD600, and went on to earn its own cult status.  The new millenium saw a rise in genres of electronic music and Sennheiser scored in its response with this warmer, bassier cousin to the HD600. This became one of the most important models in Head-Fi ever to have been released, justifying its place in the headphone history books. [See Product Desc.

We've seen lots of faces turn blue, pink, purple, green from trying to detach a cable from IEMs with MMCX connection. Corners of shirts were pulled, fingers getting dented from pure brute force. Nails broken- but agony's over when the colour of genius is yellow, yellow like these little helpful clips so you retain your composure during an extreme cable test launch event, or when you're braids shopping. Why do we spend time writing about a wee clip like this? We don't know, but we hope you enjoyed reading about it. #wesodrama

Cayin Audio were R2R pioneers in a smart music player, but the advent of the R2R RU6 USB-C DAC/amp dongle establishes them as masters of the fully-discrete resistor DAC topology in portable audio. Entering 2022, this is all it takes to achieve the buttery, natural and resolving sound, plus imaging depth, R2R is known for. Building a discrete R2R DAC in N6II/R01 had already been no mean feat. Yet to have gone one further, and implemented a 4.4mm DAC dongle for Android, iPads and laptops is a most ambitious step for R2R. It's worth it to Headfonics who cite RU6's "analog" approach, and the innovation extending to its volume control is lauded by Headfonia. [See Product Desc. For More] It gets harder every time it gets smaller, so RU6 marks Cayin as masters showcasing how they can make it work. Descended from R01, RU6's boasts a chain of 96 0.1% precision, temperature stable, resistors. That imparts a fidelity to mobile audio not yet experienced. Over 200 mW of balanced power gets most earphones and headphones loud, on the move. ecoustics say RU6 "is not only very unique but also one of the best of its kind". Everyday Listening rates "RU6’s wide stage and analogue-like note presentation granting it one of the sweetest and most euphonic sounds I’ve encountered". After thorough comparisons with other options, Twister6 qualifies RU6 as capable of replacing entry-level music players. Prime Audio Reviews confirms it differentiates itself from other DAC/amps, and it's Ear Fidelity's Best Portable DAC of 2021. Your music will be decoded up and down RU6's 24-bit ladder of individual resistors, crammed into its thumb-sized chassis over two separate six-layer PCBs. The actual R2R ladder DAC is kept apart from signal processing to lower noise. We pay attention when Cayin implement RU6 ala typical R2R – with a NOS (non-oversampling) mode. That's double the feat because the precision demanded goes up. Amidst minimal digital filtering, R2R's analog-like goodness gets delivered unmolested to your ears. Lovers of reference sound need not fret, however, with RU6's ability to switch from NOS to oversampling mode for the cleanest possible result. That scrubs any last distortion and artifacts beyond the audible human hearing range, leaving you to just enjoy your music, naturally, via one more Cayin innovation yet. That precision is backed up by a low-power, fully analog, volume control solution. A series resistor operates with shunts as voltage dividers in tandem with relays, to maintain near-perfect resolution of your music and a signal-to-noise ratio of over 110 dB. A totally novel volume solution has made this a feat for a USB-powered dongle DAC; let alone a R2R one.  Take all 30g of the RU6 built from CNC aluminium with you in your pocket, bundled with a USB-C cable as stock for all your mobile devices, with additional leather cases and Lightning-to-USB-C cable (not MFI-certified) sold separately.  Also check out the rest of Cayin's releases here, or view our other DAC/amps here.

What a statement Bluetooth like Bathys Dune is. Through it Focal invites anyone, to listen anywhere. In clear and obvious style. Focal's trademark M-shaped aluminium-magnesium dynamic driver brings you flagship sound on the go. 5 ⭐ came from What Hi-Fi? because "the success of Focal's first effort" isn't surprising. Headfonics say Bathys "represents a serious upgrade on consumer headphone choices from the likes of Sony and Bose", something Digital Trends second.  Wired writes Bathys is Bluetooth "even staunch audio nerds can enjoy". Superb acoustics on the part of Focal's know-how are a given, and the warm, rich and detailed fidelity of Bathys breaks new ground for a portable headphone of its size – wired or unwired. However, what makes Bathys truly compelling is its range of noise cancelling, Bluetooth 5.1, Qualcomm® aptX™ Adaptive and app-controlled EQ. [See Product Desc. For More] Its name comes from the French word ‘bathyscaphe’, the first submarine exploration vehicle. And Bathys is the embodiment of calm, depth and absolute silence. It's already scooped up TechHive's Editors Choice award, and is ecoustics' favourite noise-cancelling headphone for 2022. Audioholics says Bathys "takes its place among the top sound quality-focused wireless headphones available", and gave it a Product of the Year award. Stuff slapped 5 ⭐ on this Bluetooth beast too. Audiophile-Heaven lauds Bathys. At the cutting edge of tech, but dressed up in finery as a finished product like only Focal can. Blurring the lines between lifestyle and audiophilia has become typical from France's masters of savoir faire. Bathys is proof that Focal has mastered that.  The Bathys design comes inherited from Focal’s open and closed-back audiophile headphones such as Clear MG and Radiance. The earcup grilles repeat Focal’s design language, highly aesthetic curves drawing attention to the company's prestigious logo symbolising style, luxury and belief in better. A white back-lit system beneath the logo may be activated if desired, for an understated, chic effect. Another standout feature of Bathys is its elegant and timeless black-silver colourway, for effortless sophistication. Indeed, this wireless Focal is something you want to be seen with, but also to hear. The comparisons to its bigger audiophile siblings visually are apt, but so are they sonically. Bathys promises a big chunk of Focal fidelity on the move, its M-shaped aluminium-magnesium drivers among the most audiophile-grade mounted in a wireless headphone before.  This driver's stiffness, light weight and damping not only promises you a warm, immersive and authoritative presentation of music in stock tuning. It's also fine ground for EQ to be implemented – and Bathys comes together with EQ pre-sets for listeners to select via the Focal & Naim control app for iOS and Android. Not only does Bathys sound excellent – it can be made yours truly, too, when you select your favourite sound signature.  aptX™ Adaptive ensures wireless transmission stability in most conditions.  Focal added a Silent mode of cancellation optimised for trips with high background noise but let's you switch to a Soft mode to aid concentration at work, while Transparency mode enables you to stay connected to your surroundings. And a USB-C cable gives you the listener the final ability to access Bathys' 24/192 DAC via a computer or phone, when seeking uncompromised fidelity. The sense of completeness in Bathys' package promises that form and function have truly met. Despite its humble entry into the world of Focal, Bathys is in fact one of Focal's proudest Head-Fi releases. And there is much more to explore from Focal for those seeking ever-greater levels of wired sound quality here, and you can also browse all of our Bluetooth headphones here.

The Best Naming Award goes to ZMF Headphones in 2020! Every ZMF owner with Zepp gets the Pilot Pad, and sometimes they get it for other headphones too, but there were some that did not fit. Well, not anymore. Read what ZMF Headphones had to say about it:  "We designed the Co-Pilot to make your headphones feel weightless and it’s true! When the Co-Pilot is attached, your headphones feel like they're floating! Compared to the original Pilot Pad, the Co-Pilot offers more surface area, larger foam pads, and two-sided Velcro attachment with a thinner, sleeker profile. This design will work with headphone bands that range from 1.95in (48mm) wide and 0.1in (2.5mm) thick to 1in (25.4mm) wide and 0.5in (12.2mm) thick. The total area allotted for headband attachment is 2in (50.8mm). The Co-Pilot was designed to work with most headphones, but it’s not guaranteed to work for every headphone. If you’re one the fence, the Co-Pilot is the safer choice regarding fit." ===All pad sales are final. No returns, refunds, or exchanges for hygiene reasons.

An utterly modern device, GO blu reflects iFi Audio's understanding of new-age listeners. This Bluetooth 5.1, LDAC and aptX HD receiver is also a balanced 4.4mm amplifier, giving you all the power you need with a battery life of up to 10 hours. And, it's as small as your AirTag. How iFi stuffed in its balanced circuit, Qualcomm QCC 5100 Bluetooth receiver and outboard Cirrus Logic CS43131 DAC chip is a closely guarded secret they won't be telling anyone in a hurry. [See Product Desc. For More] Convenience aside, GO blu is a genuinely audiophile design with boutique parts and an attention to circuit detail – including direct coupling – that belies its use cases and form factor. Headfonia puts this iFi through its paces, and it won this race. Just like What Hi-Fi? awarded GO blu 5 ⭐ and an Applause Award followed from StereoNET. Headfonics love "it's appropriately named a pocket rocket because that’s what it is". MOONSTAR Reviews echoes that praise. That's proven in iFi's USB-C socket that doubles as charging input and wired DAC input, if you'd like the ultimate in pocket fidelity. Enjoy it to its maximum via the 4.4mm cable supplied with Audio-Technica's MSR7b – or at home with any one of iBasso Audio's SR2 or Focals via a CB17 cord.

HiBy Music's new Android 12 R4 discrete Class A music player is just such an example, being whatever you want it to be – a pocket rocket compact travel companion or beginner DAP.  We've seen this before: just HiBy pushing the boundaries of what's capable at the very top, but also at the bottom. Built on four low-power consumption ESS Technology DACs and two dedicated word clocks, pocket rockets like R4 – at this price – were what Head-Fi used to dream about. Able to decode streams off Spotify, Hi-Res Lossless Apple Music, Tidal and whatever you could download from HiBy's open Android Google Play Store, R4 is an affordable audiophile's dream. It goes right onto Headfonia's Recommended Buys list and into Audiophile-Heaven's Hall of Fame. It punches above its weight to Headfonics. "R4 punches well above its weight, while elevating music playback and user experience beyond anything else I’ve personally used in this price range" says The Headphone List. That fidelity flows on to be translated into difficult, committed audiophile IEM loads too. Eschewing the de rigueur op-amps that you've gotten blaissé about – the ones that other manufacturers fit even into their mid-tier players – HiBy asks you to choose R4's superior discrete Class A output stage instead. [See Product Desc. For More] For an entry-level player, working with high open-loop performance before feedback is applied is no mean feat ... not to mention being able to handle considerable current and provide actual power into low-impedance IEMs. Distortion always remains low when you're listening, helped by its amplifier's Class A operation. 16 output transistors are fully biased to achieve their most linear open-loop operation, ensuring an accurate reproduction of your music without the excessive use of negative feedback.  This means that the increasingly low impedances of modern IEMs will be dealt with adequately. R4's output devices are truly capable of handling current and outputting up to 525 milliwatts of power – it's not a player that will lose composure dealing with loads from Empire Ears and Vision Ears. Picking this HiBy up quickly on the go does not mean sacrificing fidelity. Using op-amps would have been too easy, and HiBy firmly stick by their discrete amplification guns even at R4's price of entry. It's a level of detail that's paid off in natural, accurate sound, reproducing the detail its quad of ESS ES9018C2M DACs are capable of. The attention paid to R4's digital decode extends beyond its DACs, its FPGA and dual crystal oscillators – it's in HiBy's desire to split its quad array of chips into two pairs. One pair decodes PCM, and the other DSD. By recognising the completely different requirements in decoding each format, R4 keeps impressing us below the surface. Specially configuring a pair of its DACs, and their ensuing analog low-pass filters (LPF), means HiBy are in a much better position to bypass DSD's problems and decode the format purely. R4's DSD decode path benefits greatly from its LPF's stronger rejection of ultrasonic noise, in particular preventing single-rate DSD64's noise problems from contaminating the subsequent signal path. HiBy might have gone in all in on the consumer market with R4, but that never stopped these innovators from respecting their audiophile roots. It then backs up that distortion and noise performance with all the luxuries that a modern music lover counts on. Android 12 and Google Play Store's apps run smoothly thanks to a Snapdragon 665 CPU, for up to 11 hours on a single charge. Seasoned audiophiles needing a compact and rugged travel companion will not find themselves missing their reference DAPs very much at all, given how high R4 gets you up the tree in performance. Similarly, newcomers will be treated to the full audio experience very quickly – and in painless financial manner. If you've graduated from R4, be sure to check out HiBy's other marvels here too, or view all our other music players here.
