If you want open-back reference listening with a stated focus on accurate bass response, choose Harman AKG Pro Audio; if you need a more forceful low end for studio work, choose AKG Pro Audio K712. For hiking, though, neither is a practical pick: both are wired, over-ear, open-back headphones rather than portable earbuds.
That distinction matters more than the small differences between them. The K701 emphasizes detailed, balanced listening, while the K712 is described as having stronger low-end performance. Neither offers noise control or a wireless connection suited to trails, so shoppers searching for the best earphones for hiking should look beyond this pair.
• Harman AKG Pro Audio K701 strength: open-back sound and a Varimotion diaphragm designed for accurate bass and detailed highs. Trade-off: fixed, 3-meter cable and no noise control.
• AKG Pro Audio K712 strength: open-back presentation with a stated 3 dB improvement in low-end performance. Trade-off: also wired and without noise control.
• K701 fit: listeners who prioritize reference-style detail and a stated frequency range of 10 Hz to 39.8 kHz.
• K712 fit: studio listeners who want a more pronounced low end while keeping an open, spacious presentation.
• For hiking: neither is a strong match; in-ear earbuds for hiking are a more appropriate category than either over-ear, wired design.
The K701 is an open-back, over-ear headphone built around detailed listening. Its Varimotion two-layer diaphragm is intended to support sparkling highs and accurate bass response, while the design lists a frequency range of 10 Hz to 39.8 kHz. The padded leather headband and shaped 3D-form ear pads point toward long listening sessions at a desk, where comfort and sound detail matter more than portability.
I’d consider it for someone who listens in a quiet room, works with audio, or wants to hear a spacious presentation at home. Its 62-ohm impedance and 105 dB SPL/V sensitivity are useful context for matching it with a listening setup, but they do not make it a wireless or trail-ready product. The cable is fixed and 3 meters long, which can be convenient near a desk and awkward when moving around.

The K701 is a poor fit for a hiker who wants compact, untethered audio. It has no noise control, and its open-back design does not create the enclosed listening environment many people want outdoors. The headphones are also not described as water-resistant or designed for exercise, so I wouldn’t infer that they are suitable for those conditions.
The K712 is another open-back, over-ear wired headphone, but its main point of difference is a stated 3 dB improvement in low-end performance. AKG positions it for precise listening, mixing, and mastering, with a spacious, airy sound presentation. It shares the K701’s 62-ohm impedance and dynamic-driver type, while its stated frequency range is 20 Hz to 20,000 Hz.
I’d steer a listener toward the K712 if they want the open-back format but prefer a more prominent low end for studio or focused home listening. Its over-ear design is intended for comfort during extended work sessions. Those details make it a considered option for a desk or studio, not a general-purpose travel headset.
The trade-offs are familiar: it is wired, open-back, and has no noise control. The product information lists Bluetooth 4.1, but the connectivity technology is also identified as wired and the specified connection is an XLR jack. I would not treat that Bluetooth field as evidence of a usable wireless listening mode. For a hike, the K712 still lacks the defining convenience of a compact, genuinely wireless earbud.
• Best for a stated focus on accurate bass response and sparkling highs → Harman AKG Pro Audio K701. Its diaphragm design is specifically described in those terms.
• Best for more pronounced low-end performance → AKG Pro Audio K712. Its low-end performance is stated to improve by 3 dB.
• Best fit for a quiet home listening space → either. Both are open-back, over-ear designs; choose based on whether you prefer the K701’s detail-focused description or the K712’s stronger low end.
• Best for a fixed desk setup with a long cable → Harman AKG Pro Audio K701. Its cable is specified as 3 meters, though it is not detachable.
• Best for mixing and mastering as described by the manufacturer → AKG Pro Audio K712. It is explicitly positioned for those studio tasks.
• Best for hiking → neither. Both are over-ear and wired, and neither has noise control.
• Best multipoint wireless headset for hiking → neither. These product details do not establish multipoint connectivity, and the K701 is wired.
• Best match for shoppers seeking in-ear earbuds for hiking → neither. Both models are over-ear headphones, not in-ear earbuds.
The category mismatch is important. An open-back headphone lets its design prioritize a spacious presentation, but that does not translate into a sheltered, portable listening setup. A cable can snag or limit movement on a trail, while an over-ear format is less compact than earbuds. Those are practical conclusions from the stated designs, not claims about how either model performs in outdoor conditions.
For indoor listening, the choice is much closer. Both use a 62-ohm specification and dynamic drivers, and both have open-back construction. The K701’s listed frequency range extends lower and higher on paper, but that specification alone does not tell the whole story of what a listener will prefer. The K712 instead makes a more direct case for itself through its stated low-end improvement and studio focus.
Comfort is another reason to keep the intended setting in view. The K701 lists shaped 3D-form ear pads and a padded genuine-leather headband. The K712 is described as an over-ear design intended for long work sessions. These are useful design cues for stationary listening, but they do not establish how either will feel on every person or during a hike.
If your real goal is outdoor listening, search for a product designed around that use: an in-ear or compact wireless form, with connectivity and durability details that suit the conditions you expect. Neither of these AKG models can be fairly called the best earphones for hiking based on the available specifications. They are better understood as two wired studio-style headphones with different tonal priorities.
I’d choose the AKG Pro Audio K712 for indoor use because its stated 3 dB low-end improvement gives it a clear point of difference for studio listening. I’d choose the K701 instead if accurate bass response and its stated wider frequency range matter more to me. For hiking, I recommend neither; I’d look for purpose-built earbuds instead.
Neither is a good hiking match based on the listed design. Both are over-ear, open-back headphones, and the K701 has a fixed 3-meter cable; neither lists noise control.
What is the main sound difference between the K701 and K712 Pro?
The K701’s product details emphasize accurate bass response and sparkling highs from its diaphragm design. The K712 is described as having a 3 dB improvement in low-end performance, making that the clearest stated distinction.
The K701 is listed as wired. The K712 product details include a Bluetooth 4.1 field, but also specify wired connectivity and an XLR jack; they do not establish multipoint wireless use.
“Value” depends on what you need from the headphones. Check the current price on Amazon, then weigh the K701’s stated detail-focused design against the K712’s stronger low-end performance and studio positioning.
