OneOdio A70 review

The only pair here that works without a cable: 72 hours of wireless playtime, two wired cables in the box including a 3.5-to-6.35 mm (1.38 in) lead, a locking jack and a built-in microphone for calls.

What it amounts to The one pair here that leaves the desk: 72 hours wireless, two wired cables, a locking jack and a microphone. It publishes no impedance and no frequency response, and Bluetooth is for listening rather than for monitoring.

Bluetooth and wired, with 72 hours of playtime and two cables in the box — 3.5 mm to 6.35 mm and 3.5 mm to 3.5 mm. 40 mm neodymium drivers behind an aluminum fascia. A jack lock on the aux plug. Audio sharing. A built-in microphone with noise reduction. Rotatable and foldable.

This is the only wireless pair on the shelf, and the 72 hours is the only battery figure on it. Both facts need the same qualification: wireless is not for monitoring. Bluetooth audio arrives tens of milliseconds late, and hearing your own playing that late is unusable — which is why the other nine pairs here are wired only, and why this one ships two cables rather than one.

Read the right way round, that makes it two products. On the desk it is a wired monitoring pair with the right adapter already fitted. Away from the desk it is a wireless pair that lasts three days.

The two cables are worth more than they look. Four of the ten listings here supply an adapter of some kind; this supplies a whole second lead, so an interface at 6.35 mm (0.25 in) and a laptop at 3.5 mm (0.14 in) are both covered without anything screwed on.

The jack lock is the detail nothing else here has. A monitoring cable gets pulled sideways every time someone leans towards a keyboard, and a friction-held plug loses one channel before it loses both — which sounds like a problem with the mix rather than with the cable. It is the only statement about a cable connection anywhere on this shelf.

What it does not publish is the same list as every American listing in this family: no impedance, no sensitivity, no frequency response. The two pairs here that publish those figures are both European, and one of their pages says plainly that 32 ohms is what tells you a laptop can drive them.

The product record gives 254 g (9 oz).

In its favor, and its limits

Strengths

  • The only pair on this shelf that works wirelessly, with the only published battery figure — 72 hours
  • Two cables in the box, so neither an interface nor a laptop needs an adapter
  • A locking jack, which addresses the way a monitoring cable actually fails

Compromises

  • A wireless connection adds latency, which is why no studio monitoring is done over Bluetooth
  • No impedance and no frequency response published
  • The aluminum fascia and the folding hinge are two more parts than a fixed plastic headband has

The questions players ask

Can I monitor over Bluetooth?

Not while recording. Wireless audio arrives late — tens of milliseconds — and hearing your own voice or your own playing that late is unusable. That is why every other pair on this shelf is wired only and why this one ships two cables. What the wireless mode is for is listening: playback, reference tracks, and the 72 hours on the train afterwards.

What does a jack lock actually prevent?

The plug working its way out of the socket. A monitoring cable is pulled sideways every time someone leans to a keyboard, and a 3.5 mm (0.14 in) plug held by friction alone drops one channel before it drops both — which sounds like a fault in the mix rather than a fault in the cable. This is the only listing on this shelf to address it, and the only one of the ten to mention the cable’s connection at all beyond its length.

Who should pick this one, among music instruments and gear

A pair that monitors on a cable at the desk and plays music on the train, where 72 hours means not thinking about charging.
