If you're into portable audio, the Headroom Show is a good place to be - headphones, portable music players and pocket-sized headphone amps/DACs are all on display and ready to be auditioned. Those using headphone-based home systems are also catered for with options, to suit a wide range of budgets, hooked up to headphone amps ranging from the perfectly affordable to ultra high-end.
Here are a few of our favourite highlights from the show...
Chord Hugo 2 DAC
The Chord Hugo 2 headphone amp/DAC was officially launched at CES in January and has to be one of the most eagerly anticipated hi-fi sequels of 2017. It's the successor to the five-star, Award-winning Hugo, with differences including a brand-new button layout and trimmed-down chassis.
The Hugo 2 has four digital inputs, including optical, coaxial and USB, plus Bluetooth. Various high-res audio formats are supported, including DSD512. Review samples are imminent, so be sure to stay tuned to What Hi-Fi? for our findings...
Cyrus soundKey DAC
The Headroom Show was the first time we'd seen Cyrus' new micro-DAC in the wild. The British hi-fi manufacturer actually turned to Kickstarter to help fund the soundKey and managed to rustle up nearly £80,000 in backing.
The soundKey is designed to be a portable DAC for use with smartphones, hence the support for a wide range of audio formats including MP3, AAC and FLAC. High-resolution audio is also on the menu, with the DAC able to natively support 24-bit/96kHz files.
It's available in four different finishes (black is the only one not in the photo) and will cost £99 when it officially goes on sale in a couple of months.
Even H2 Bluetooth headphones
Even showcased a range of headphones it dubbed "glasses for your ears". Key to each of the headphones, including the upcoming H2 Bluetooth model pictured above, is the built-in calibration software which takes readings for each of the wearer's ears based on responses to various test-tones. The accompanying app then creates a unique 'earprint' which you can store and see online.
The H2s cost $299 and claim 20 hours of battery life from a 52min charge. Controls for playback are built into one of the enclosures, each of which uses a 40mm driver.
Focal Utopia headphones
Focal might be better known for its high-end speakers, but the company also has a line of high-end headphones. The flagship is the £3250 Utopia.
They're the first to sport fully open-backed, full-range drivers with Beryllium 'M'-shaped domes - a design derived from the company's high-end Utopia loudspeakers.
We've just finished our review of this very pair of headphones, so keep your eyes peeled as we reveal all in the coming weeks.
Goldmund THA 2 headphone amp/DAC
There was no shortage of headphone amps on display at the show, but Goldmund's THA 2 offers something slightly different. Besides a wide-band amplifier, digital volume control, high-res audio support and a selection of digital inputs, the THA 2 also features its own binaural processing.
Flicking a switch on the front of the £9500 unit engages a built-in algorithm which Goldmund claims promotes a more balanced and clearer sound.
Grado GS2000e headphones
Headroom saw Grado's latest over-ear headphones, the GS2000es, make an appearance. These £1600 open-backed cans combine two different wood types (maple and mahogany) to make the enclosures for the purpose-built 50mm drivers.
Grado claims the maple "allows the energy of the sound to be transmitted," while mahogany "allows it to open up and reveal the harmonic structure and space that the artist intended."

Those who want a real taste of the high-end could head straight to HiFiMan, with its impressive-looking Shangri-La system on display. Consisting of electrostatic headphones and dedicated tube amplifier, this tag-team costs a cool €50,000.
The amp includes four custom-made 300b tubes while the headphones use HiFiMan's Ultra-Thin Driver nanotechnology, which claims "lightning-fast response with virtually zero distortion."
Pioneer XDP-30R portable music player
A brand new launch, exclusive for Headroom, was the Pioneer XDP-30R. It's a portable high-res audio player that, at £350, comes in under Pioneer's current XDP-100R.
The touchscreen-equipped player boasts a 15-hour battery life, expandable memory and hi-res audio support including DSD and 32-bit/192kHz files. There's also an MQA update scheduled for shortly after the player goes on sale on May.
Sennheiser Orpheus HE 1
It's not every day you get to experience a £54,000 headphone-based hi-fi system, but Sennheiser's Orpheus HE 1 sat proudly on display at the show. And a lucky few were able to have a quick listen.
The HE 1 combines electrostatic over-ear headphones with a valve-driven, hybrid headphone amp, all presented in a case of solid marble. Left and right channels use four DACs and four valves each, with the amp also offering a mix of analogue and digital inputs.
