This accessory may be the easiest way to listen to Hi-Fi audio from your phone
Campfire Audio's Relay accessory is a dinky new DAC/AMP that slides into your pocket without kicking up a fuss. Yet it still promises to deliver the kind of sound usually reserved for amps the size of bricks and the weight of top dollars.
From the outside, Relay is sleek, aluminium-clad, and unapologetically premium. Inside, it's packing an AKM 4493 SEQ DAC chip, which might not mean much to your average Spotify-on-a-smart-fridge user, but those who've flirted with the idea of Hi-Fi on the go will be excited. The chip adds a bit of analogue charm to your digital music – promising a hint of warmth and a smidge of character.
This thing can basically connect to any device. It has a USB-C connector and works with Windows, MacOS, iOS and Android. It even plays nice with gaming PCs, in case you want to take your gaming to the next level (pun fully intended).
There's a real sense that Campfire Audio has tried to make the Relay not just portable, but usable. You get both 3.5mm and 4.4mm outputs, high and low gain modes, six filter options, support for up to 32-bit/768kHz playback, PCM and DSD formats, and even media playback controls.
Campfire even included a bunch of thoughtful extras. You get a short USB-C cable that won't tangle, a microfibre cloth for the inevitable fingerprints, and a plush little bag to keep it all snug.
The Campfire Audio Relay DAC/AMP is available now directly from the brand, Amazon US, Amazon UK, and specialist audio retailers. It'll set you back £229/$229, which is pretty comparable for this kind of device.

I think this is the best charging cable ever – here's why
If you're anything like me, you've got more than two gadgets on you at all times – oftentimes a lot more. I've got a smartphone, smartwatch, and fitness tracker, which is the bare minimum. And there's nothing worse than having to carry around different adapters and chargers for various devices. But OnePlus has come up with a charging cable that I think is perfect. 2-in-1 chargers are nothing new, but they're a bit bulky – even the ones that fold. That's why OnePlus's solution is genius. It's just a charging cable, but it can juice up your smartwatch as well. Read more: Best wireless charger in 2025 including charging stands and pads OnePlus' new cable combines a USB-C plug for your phone, a unique OnePlus smartwatch connector, and a USB-A end to plug into your power brick of choice. Unfortunately, that POGO Pin connector for the watch means it's strictly a OnePlus-only party – you won't be able to use it with Galaxy or Apple Watches. But if you're in the OnePlus ecosystem, this cable is as close to perfect as you can get. Although, I do wish it was USB-C at both ends. When plugged in, your phone gets 80W of charging power on its own, or 67W if your smartwatch is also in on the action. The watch pulls a respectable 10W itself. This is much faster than most other 2-in-1 chargers, since they're wireless. Plus, the cable measures 1.2 metres, so you won't have to crouch next to an outlet to use it. The OnePlus 2-in-1 SUPERVOOC cable is available to order from the OnePlus store. It'll set you back $30/£25, which is on the pricey side for a cable, but not too shabby for a 2-in-1 charger. If you're a OnePlus phone and watch owner, it might just be the most useful travel gadget to throw in a bag.

Rode's Wireless Micro Camera Receiver is the best kind of upgrade
When Rode launched its mobile-friendly Wireless Micro at the end of 2024, it was really all-in on smartphone content creation. Ideal if your social clips and YouTube footage are filmed exclusively on a phone – but less so if you routinely swap between your handset and a more capable digital camera. The Aussie firm has now added the Wireless Micro Camera Receiver into the mix for a little extra inclusion – and the great news is that anyone who already owns a Wireless Micro can claim the new receiver for free. This handy clip-on, available in black and white colours and with USB-C or Lightning connectivity, has universal camera support – no no-one is left out, no matter what they shoot on. It can be paired with up to two Wireless Micro transmitters for dual channel recording, and has a familiar feature set including smart gain control and plug-in power detection to maximise battery life. It plays nicely with all of Rode's software, including the Rode Capture iOS video app, Rode Central, and Rode Reporter. You get a flexible 2.5mm microphone cable in the box, along with a USB-C charging cable (seeing as there's no room in the Wireless Micro's charging case for any extra kit). A 100m+ transmission range and 18 hours of recording time should mean it'll cope with the sort of situations critical to content creation. A full recharge should take around 2 hours. The Wireless Micro Camera Receiver will now come bundled with the Wireless Micro as standard if you buy one from the Rode website (and are based in Australia, Europe or the UK). New customers in the United States will have to register in order to claim theirs post-purchase. Existing Wireless Micro users will also have to head to register their product, and pay the shipping fee in order to bag a bonus Wireless Micro Camera Receiver.

This accessory may be the easiest way to listen to Hi-Fi audio from your phone
Got a killer pair of headphones, but nothing to plug them in to? Or maybe, you want to listen to Hi-Fi audio on your cans, but your device (such as a smartphone) can't output the audio. You'll need a DAC – they're usually quite fiddly, but not this one. Campfire Audio's Relay accessory is a dinky new DAC/AMP that slides into your pocket without kicking up a fuss. Yet it still promises to deliver the kind of sound usually reserved for amps the size of bricks and the weight of top dollars.
