If you want wireless listening and long battery life for running, choose OneOdio A70; if you need a foldable wired pair for studio gear and single-ear monitoring, choose OneOdio A71. Neither is described as waterproof, so neither is a sound choice for someone specifically seeking IPX7 waterproof earphones for running.
OneOdio A70 vs OneOdio A71 at a Glance
• OneOdio A70 strength: Bluetooth 5.2 and up to 72 hours of wireless playback; trade-off: no listed water-resistance rating.
• OneOdio A71 strength: foldable design, swiveling earcups, and wired 3.5mm and 6.35mm connections; trade-off: it is a wired-only model.
• A70 fit: choose it for wireless listening, long stretches between charges, and the option to connect to studio equipment.
• A71 fit: choose it for a studio, instrument, or computer setup where a coiled cable and single-ear monitoring are useful.
The A70 is the more practical pick if you want wireless over-ear headphones for everyday listening. Bluetooth 5.2 lets you pair them with a compatible device without keeping a cable attached, and the stated wireless playback time is up to 72 hours. That combination suits long listening stretches at home or on the go, especially if frequent charging is something you would rather avoid. The listed Bluetooth range is 10 meters, which can give you some room to move away from a paired device.
For running, the A70 has one clear advantage over the A71: wireless listening means there is no audio cable running from the headphones to your phone or player. That is a convenience, not a claim that these are sport-specific headphones. They are over-ear headphones, and the product information gives no water-resistance rating. If your priority is a dedicated, sweat- or rain-ready option, do not mistake wireless capability for waterproofing.
The A70 also supports wired listening through a 3.5mm connection and has 3.5mm and 6.35mm jacks for connecting to audio equipment. Its 40mm dynamic drivers, 32-ohm impedance, and listed 20Hz–20kHz frequency range provide useful context for a general listening and studio-oriented design, but they do not establish how it will sound to every listener. The supplied audio-sharing arrangement lets another pair of headphones connect so two or more people can listen together.

The A71 is the simpler choice for a listening setup built around cables. It is wired rather than Bluetooth, with 3.5mm and 6.35mm connections for use with sources such as computers, amplifiers, keyboards, and guitars. Its included coiled cord extends from 6.6 to 9.8 feet, giving you extra reach around a desk or studio space while keeping the headphones connected to the source. The cable’s two plug sizes also reduce the need to find a separate adapter for compatible equipment.
Its 90-degree swiveling earcups support single-ear monitoring, which can be handy when you want to keep one ear free during a recording or mixing session. The A71 is also described as foldable, with the earcups folding inward for easier storage or transport. Those details make it a more specialized fit for someone moving between a home studio, a computer, and instruments than for someone who mainly wants cable-free listening.
Comfort details include padded ear cushions and an adjustable, stretchable headband. A shared audio port allows another pair of headphones to connect for shared listening, and the product information also describes a cable lock intended to help keep the connection secure. Its 40mm dynamic drivers, 32-ohm impedance, and 20Hz–20kHz frequency range are specified, but those numbers alone cannot promise a particular sound preference or studio result.
Who should skip it: Skip the A71 if you need Bluetooth for movement or running, or if you want a wireless pair without a cable connected to your device.

My Verdict
Before choosing, think about how you will connect the headphones most often. The A70 is the more flexible option if you want Bluetooth for daily listening and the possibility of a wired connection for compatible equipment. The A71 is made for a cable-first setup, with 3.5mm and 6.35mm plugs and a coiled cord that can extend up to 9.8 feet. If you regularly move between devices with different audio jacks, those connections may matter more than wireless features.
Also consider how much the fit and handling details match your routine. The A71’s folding earcups and 90-degree swivel support storage and single-ear monitoring. The A70 instead emphasizes wireless playback and audio sharing. Both are over-ear designs, but the product details do not provide a waterproof rating for either. That distinction matters for a shopper searching for the best foldable headphone for running: folding is useful for carrying, but it does not establish that a headphone is suitable for sweat or rain.
If you are comparing the A70 with IPX7 waterproof earphones for running, treat that as a different category of decision. The provided details for the A70 and A71 do not state an IPX7 rating—or any water-resistance rating. For wireless headphones for running, the A70 has the more relevant connection style of these two, but the available specifications do not establish a secure athletic fit, sweat resistance, or weather protection. Check the current product details for the specific use you have in mind rather than inferring those qualities from Bluetooth support.
Finally, decide whether a microphone, cable-sharing option, or studio compatibility is part of your real routine. The A70’s information mentions call control and a microphone, as well as connecting additional headphones for shared listening. The A71 focuses more on wired sources and monitoring, including its swiveling earcups and shared audio port. Neither model needs to be the right fit for every use: choosing around your actual devices and listening habits is more useful than choosing by driver figures alone.
The A70 is the more practical of these two for running because it supports Bluetooth, so there is no audio cable connecting it to your device. Neither product’s listed details include a water-resistance rating, so the information does not establish that either is suitable for sweat or rain.
The A71 is listed as a wired headphone, with 3.5mm and 6.35mm connections. Bluetooth operation is not specified for this model, so choose it for a cable-based setup rather than wireless listening.
Both models include 3.5mm and 6.35mm connection options in their product details. The A71 is specifically described for sources such as amplifiers, computers, keyboards, and guitars; the A70 offers Bluetooth as well as wired connections.
Both describe a way to share listening with another pair of headphones. The A71 has a shared audio port, while the A70 describes a cable-based connection for additional headphones. Check which connection arrangement best fits the headphones you already own.
