OneOdio’s £49.99 headphones combine an enormous battery with wireless listening, app-controlled audio and direct connections for phones, computers and professional music equipment
OneOdio's new Fusion A70 Gen 2 headphones are trying to cover an impressive number of bases for their launch price of just £49.99. They can be used wirelessly with a phone, plugged into a laptop using a standard 3.5mm connection, or connected directly to DJ and studio equipment through a full-sized 6.35mm input.
Add in a 72-hour battery life, LDAC audio and Bluetooth 6.0, and they begin to look almost suspiciously well equipped for the money.
They’re an updated version of OneOdio's popular A70 headphones, with app support, improved connectivity and a more secure locking connection for the 3.5mm socket.
The result is a versatile pair of headphones that makes a lot of sense for home listening, gaming and casual music production. Perhaps not something an audiophile will wake up in a cold sweat over, but affordable tech is always something to be celebrated.
What I liked about the OneOdio Fusion A70 Gen 2
The best thing about the A70 Gen 2 is its flexibility. Most affordable Bluetooth headphones give you a wireless connection and perhaps a 3.5mm socket for emergencies. OneOdio provides both 3.5mm and 6.35mm connections, so you can plug directly into a phone, computer, amplifier, keyboard, mixing desk or turntable setup without digging around for an adapter.
The headphones will also continue working through a cable when the battery is flat. There’s a music-sharing function, too, which allows another pair of headphones to be connected to the spare socket.
Bluetooth 6.0 supports multipoint pairing, letting the A70 Gen 2 remain connected to two devices. That’s useful if you regularly swap between a laptop and phone, although the handover isn't always instantaneous.
The battery life is another major strength. It'll vary depending on how hard you're pushing them, but they should comfortably get through several days of heavy listening.
The sound they produce is entertaining rather than clinical. The 40mm drivers produce a warm, punchy presentation with plenty of weight in the bass, while the midrange remains clear enough for vocals, podcasts and films.
Treble has been kept relatively relaxed, which helps prevent the A70 Gen 2 from becoming tiring during longer sessions.
The OneOdio app helps to further finesse the sound production. It includes presets and a graphic equaliser, so you can reduce the bass, bring the vocals forward or brighten the top end. Those settings only apply while listening over Bluetooth, rather than through the analogue cable.
At around 242g, they’re relatively light, with memory-foam ear cushions, a padded headband and a relaxed clamping force. The cups rotate through 90 degrees for single-ear monitoring and fold inwards when you want to put them in the supplied pouch.
What I didn’t like about the OneOdio Fusion A70 Gen 2
There’s no active noise cancellation or transparency mode, which I guess is fair enough at this price.
The predominantly plastic construction also gives the game away. They don’t appear alarmingly flimsy, and the headband has internal reinforcement, but you’re not getting the reassuring solidity of a more expensive pair.
Those soft synthetic-leather pads can become warm, too. This is common with closed-back headphones, but it’s worth considering if you plan to wear them throughout a working day.
The supplied three-metre coiled cable is useful beside a mixing desk, amplifier or keyboard, but cumbersome for portable listening. A shorter 3.5mm-to-3.5mm lead in the box would have made the package more convenient.
Overall verdict: should you buy the OneOdio A70 Gen 2?
The OneOdio Fusion A70 Gen 2 headphones aren’t going to trouble a premium pair from Sony, Bose or Sennheiser. They lack active noise cancellation, the microphone is fairly basic and the plastic construction reflects the low price.
But £49.99 buys you an unusually capable set of headphones, and they absolutely punch above their weight.
The enormous battery, LDAC support, app-based equaliser and dual wired connections make them far more adaptable than most budget alternatives.
They’re particularly easy to recommend for someone who wants one affordable pair of headphones for music, gaming, a keyboard, an amplifier and occasional DJ work.
