Alongside that, though, was one of the first outings of the soon-to-be-famous Orange hieroglyphs, with a charming accidentally reversed bass clef symbol to represent the low end, and the now-familiar clenched-fist symbol to indicate what future amps would simply call “punch”. Orange O Bones are lightweight and distribute their weight nicely. As a result, you barely feel them (apart from feeling those vibrating drivers). Bone conduction seemed like an odd direction for a company that prioritises audio quality to take, but Orange has done well with its debut effort. The O Bones make the same compromises as every rival that uses the tech, but manages to deliver a better all-round sound – and at a very reasonable price. Unless you’re a mobile gamer, you can enjoy a lag-free watching experience. That means on both Android and iOS, as well as Windows computers. Orange O Bones output decent bass, a harsh midrange, and a quiet treble. On the other hand, the sound feels very spacious.

The O Bones boast eight hours of battery life through 180MaH battery that will only require one to two hours of charging using the dedicated charging accessory, and are equipped with Bluetooth 5.0 featuring Siri and Google Assistant voice control functionality. The next rig was an Aguilar Tone Hammer 500 and matching SL 112 cabinet—a powerful and clear combination. The O Bass was again in beast mode, with robust-yet-slightly-barking tones. This bass likes moving some air, and I got a really nice old-school thump out of it by palm muting. When rolling off the tone, however, the O Bass got choked and a bit of a wet-blanket feeling came over the tone. I found that this bass wants to be played wide-open, very much like its Orange amp cousins. Orange O Bones have a stable Bluetooth connection with an above-average range (but some occasional stutters; more on that later). There’s also no audio lag when watching videos. Battery life is generally OK, averaging between six and seven hours with the volume cranked to about 80%. That falls short of Orange’s eight hour estimate, and can’t compete with the pricier Shokz OpenRun Pro and its near nine-hour runtime. Turn down the volume and it’ll last a little longer, but that also defeats the object of buying a pair in the first place. Sound quality: feel the vibeWe’d all seen pictures of the outside of the OR120 before this example arrived in the workshop. But perhaps the most interesting aspect of having one to investigate in the flesh was popping off the sleeve and seeing the creature’s guts. And what a perfectly clean, immaculately preserved example of an OR120 we had here, with the circuitry and build serving as an absolutely textbook example of how to construct an amp in 1974. The serial number dated this unit to 1974, barely five years after Orange was founded, and only two after the company began serious mass production with its first factory in Kent. The OR120 was a year-zero moment for Orange: a wholesale rejigging of the existing schematics, from which emerged a new tone that everybody would come to associate with the brand, with a design and sound that would influence the amp world, both Orange’s and other’s, ever since. And here was one of the beauties, right in front of us on the bench! BEGINNING OF A DESIGN EVOLUTION One of these occasionallys happened last week: an amp head showed up at Orange HQ wrapped in a home-sewn leather cover with an accompanying note from the original owner. The amp had been kept in storage for a while, the note explained, but now the owner was looking to give it to his son, a promising guitarist. Before he did that, though, he wanted to have the unit looked at by our expert technicians, and so here it was with us. Sure, there’s practically no sub-bass, but the upper region is decently punchy, especially on higher volumes.

Remembering to plug in isn’t always a given, though. There’s a red LED that flashes when you’re running low, but it’s impossible to see while you’re wearing the headphones – something we tend to do before actually turning them on. Shokz does it far better by audibly confirming how much charge you’ve got left every time you power them on. Orange Amplification is delighted to add the O Bones® wireless headphones to its range. Using state-of-the-art bone conduction technology, they transmit audio waves via facial bones to deliver clear, clean mid and high pitch frequencies as well as deep, rich bass tones. Rather than pushing buds into the ear canal as you do with true wireless earphones, the soft rubber cushions of the latest wireless head gear from Orange rest on the facial bones just in front of the listener's ears for audio delivery. The person on the other side of the line should still understand what you’re saying. However, try avoiding making long phone or video calls with the O Bones. bone conduction technology, they transmit audio waves via facial bones to deliver clear, clean mid and high pitch frequencies as well as deep, rich bass tones.

Lower frequencies are a known Achilles’ heel of bone conduction. However, at least with Orange O Bones, they seem to somewhat resolve the issue.

Bone conduction’s main purpose is to safely listen to music while jogging on the streets and not sonic fidelity. Orange Amplification is delighted to add the O Bones ® wireless headphones to its range. Using state-of-the-art bone conduction technology, they transmit audio waves via facial bones to deliver clear, clean mid and high pitch frequencies as well as deep, rich bass tones. The wireless Orange O Bones® offer great sound, and utilise 16mm speaker capsules to achieve a broad range of frequencies with surprisingly loud volume. Users not only hear the bass, they feel it, the mids are crystal clear and the highs are sharp and well defined. The ergo-dynamic design ensures a cosy, secure fit for comfortable listening whatever the activity. The O Bones® are also water resistant, making them perfect for running or cycling in the rain or even sweaty sessions in the gym or studio. Gear moves in and out of the Orange workshop pretty constantly, with fixes, mods and inspections to amps, pedals and prototypes all in a day’s work. Very occasionally, though, something gets sent in that makes us crowd around the workbench — something rare, old, or unusual, or just something we’ve only ever read about before.

The true test though is how well that sound performs when you need to be aware of your surroundings. I’d say the mix of audio and environmental sound feels more weighted towards the latter. I found in even moderately noisy environments like running outside in the wind or next to traffic, in a gym battling music from speakers or on the train or bus, that exterior sound really wins the battle against hearing your own audio. It’s supposed to be balanced, but that’s just not the case here. Like all bone conduction headphones, you’re going to have to accept some compromises in sound quality. That’s ultimately the nature of the open–ear headphones and bone conduction technology. The good news is that in general, things are getting better with bone conduction but in the case of the O Bones, it’s not raising the bar in terms of performance.

O Bones bone conduction headphones use Bluetooth 5.0, which is quite reliable. There are no random stutters when using the headphones close to your transmitting device.USB-C port is covered with a flimsy rubber cover that could pinch off at any moment. What Bluetooth Codecs Do They Use? What’s even more impressive is how stable these headphones are. The design uses ear hooks to keep them in place, and it’s very successful at doing so. Orange O Bones offer a secure fit that doesn’t budge, even during intense workouts. Even the indoor range is impressive, receiving the signal up to 60 feet (or 18.2 meters) in the distance. Orange Amplification is delighted to add the O Bones ® wireless headphones to its range. Using state-of-the-art bone conduction technology, they transmit audio waves via facial bones to deliver clear, clean mid and high pitch frequencies as well as deep, rich bass tones. Unfortunately, the valves had had become unmatched over the years, so that they were drawing differing amounts of current to one another — a simple function of old age — and the original Plessey capacitors, proudly stamped with “British Made”, needed replacing.
