AKG N700NC Wireless Headphones Review

These headphones have a high-end look, and a premium feel. The headband has a slightly odd shape with curved hinges which hold the ear cups, making the headphones wider. The cups are dense and have thick padding, but they only come in a silver finish and don’t offer any color variety to suit your preferred style.

The AKG N700NC are comfortable headphones thanks to the good padding on the cups and headband. They aren’t too tight and don’t put too much pressure on the head. However, they do feel heavier than similar over-ear headphones. The cups are fairly deep but aren't very large, which should suit most ears, but might squeeze bigger ears a bit.

The control scheme of the AKG N700NC is decent. You get access to common functionalities like play/call management, volumes buttons, talk-through modes, and the power/pairing slider. The buttons are decently easy to use and provide great feedback. You also get audio feedback for play/pause, max/min volume and track skipping, but not every time you change your volume, which is nice.

Like most over-ears, the AKG N700NC trap some heat under the ear cups and get warmer than typical in-ears. They create a decent seal around your ears, so there’s not much airflow and might make you sweat a bit more if you use them for sports. This shouldn’t be a problem for casual listening, especially if you take breaks here and there.

The AKG N700NC aren’t the most portable headphones since they are bulky over-ears. However, they do fold into a more portable format so that you can fit them in a bag or the included case. If you want to wear them around your neck while not using them, the cups also swivel to lay flat. For a more premium build, check out the Audio-Technica ATH-DSR9BT.

They come with a great hard case that should protect your headphones against scratches, water exposure, and impacts. The case feels fairly solid but does add a bit of bulk and make it harder to store the headphones away. On the upside, the inside of the case is molded with a plastic divider to fit the headphones, which could help protect them a bit more.

Update 05/06/2021: Some users have reported that their headphones have cracked near the swivel joints or hinges after a few months of use. Although we don't test for durability over time, your unit may be prone to breakage over time. That said, the scoring of this box hasn't changed.

The AKG N700NC have good build quality, and when handling them, you feel like holding premium headphones. They are made of thick plastic, and the headband is reinforced with a thin metal plate. The headphones feel heavier than average but are fairly flexible. The padding on the cups and headband feels comfortable, but the leather fabric might wear over time.

They are stable enough for light running but won’t be ideal for more intense workouts or sports because of their bulkier design, but they are fairly tight on the head. Since they are wireless, you don’t have to worry about a wire getting stuck on something and pulling the headphones off your head.

The AKG N700NC have great frequency response consistency. In the bass range, they seem to be using the ANC feature to check for seal and ensuring a proper bass delivery. Even people wearing glasses should get excellent bass results. In higher frequencies, they are also consistent across different re-seats below 10KHz.

The AKG N700NC have an excellent bass response. Their low-frequency extension (LFE) is at 10Hz, which is great. The entire range is flat and well-balanced, which results in a neutral bass with great low-bass for thump and rumble common to bass-heavy genres like EDM and hip-hop. Mid-bass, responsible for the body of bass guitars and the punch of kick instruments is also flat and within 1.5dB of our target, which is great. Overall, the bass range is excellent, punchy and deep.

The mid-range performance of the AKG N700NC is excellent. The response is throughout the range even and flat, and within 1.5dB of our target which is great. This results in accurate reproduction of vocals and lead instruments.

The treble performance is very good. It is rather uneven, but fairly flat across the whole range. However, it is over our neutral target curve by about 3dB, which could make the sound a bit too bright and sharp. This would be mostly noticeable on vocals, lead instruments, and cymbals. Overall, they sound good and still have a great treble range.

The AKG N700NC have excellent imaging. Their weighted group delay is 0.28, which is great. Also, according to the graph, their group delay is almost all below the audibility threshold. This results in tight a bass reproduction and a transparent treble. Additionally, the L/R drivers of our test unit were exceptionally matched in amplitude, frequency and phase response. This ensures an accurate placement and localization of objects (voices, instruments, footsteps) in the stereo image.

The soundstage performance is sub-par. The PRTF graph shows a good amount of ear activation and interaction, but it's not very accurate, and there's not a 10KHz notch present either. This and the closed-back design of these headphones results in a soundstage that is perceived to be located inside the listener's head.

The AKG N700NC have a decent noise isolation performance. The active noise cancelation achieves an average 10dB of isolation in the bass range, which is important for canceling out airplane and bus engine rumbles. However, they achieve 17dB and 34dB of isolation in the mid and treble ranges respectively which is good. This indicates good isolation performance for speech and sharp sounds such as S and Ts. If you're looking for an even better noise isolation performance, try the AKG N700NC M2 Wireless.

The leakage performance of the AKG N700NC is average. Most of their leakage is in the mid-range, between 400Hz and 5KHz, which is fairly broad. So, although the overall level of their leakage is not very loud, people around you will be able to hear your music if you blast it, even in moderately noisy places like a bus. They should be fine to use around an average office at moderate volumes without disturbing colleagues.

The recording quality of the N700NC's microphone is mediocre. The LFE of 269Hz results in a recorded/transmitted speech that is relatively thin. The HFE (high-frequency extension) of 3KHz results a speech that is muffled and lacks detail. However, it should be noted that this a limitation of Bluetooth protocol which limits the HFE of all microphones to around 3.5KHz.

The integrated mic is mediocre at noise-handling. In our SpNR test, they achieved a speech-to-noise ratio of 12dB, indicating they are best suited for quiet environments and will struggle to separate speech from ambient noise in moderate and loud situations.

They have good battery life with about 18 hours of continuous playback with Bluetooth and ANC on and take about two and a half hours to charge fully. According to AKG’s specs sheet, you can use the ANC feature for up to 36 hours if you use the headphones wired. You can also use them passively with the provided 1/8” audio cable, even if the battery is dead, which is convenient. You can also activate the auto-off timer in the compatible app to save more power. Our test result is lower than the advertised number for battery life. We plan to re-test them and will update the review if the new number is significantly different.

The AKG N700NC are compatible with the AKG Headphone mobile app, which doesn’t offer a lot of customization. You get access to a simple parametric EQ, but no presets and you can’t control the level of noise canceling in the app, which is disappointing. You can switch between ambient mode and talk-through mode, but can’t fully disable ANC. You can also enable an auto-off timer to save battery life when you’re not using the headphones.

These headphones, unfortunately, do not have NFC for quicker and easier pairing, and they can't connect to multiple devices simultaneously which would have been convenient.

Update: 05/12/2018: We've updated the Bluetooth version from Bluetooth 5.0 to Bluetooth 4.2 as displayed in the AKG N700NC spec sheet.

Like most Bluetooth headphones, these headphones have too much latency to watch video content or gaming. They also above-average default latency for Bluetooth headphones and don’t support any low latency codec. However, they can be used passively with the 1/8” TRRS cable which will get rid of the latency issues.

You can use these headphones passively with the provided 1/8” TRRS audio cable, even if the battery is dead. You won’t be able to use the ANC feature if the battery is dead. The cable is compatible with consoles for audio and microphone support. However, track skipping backwards with the in-line button doesn’t seem to work on certain Android phones, but does on some.

The AKG N700NC do not have a base/dock. If you want a versatile headset with a base that you can also use wired, check out the SteelSeries Arctis 7.
