LG GX F310L - Full phone specifications
There is no LDAC support here but considering its finicky nature that’s probably not a huge loss. Most of the testing was done using the Tidal app that offers lossless 44.1kHz/16-bit audio on the OnePlus 6T, along with some locally stored 96kHz/24-bit lossless files. I also tested the wired mode with the provided cable. The CH700N lets you keep the headphones on when the cable is plugged in. This means you are using the internal audio processing of the headphones even when you use the cable, not to mention you can also keep using noise canceling.
You can, of course, turn them off to save some power but the sound quality is significantly worse with the audio processing off and you also lose out on some of the noise canceling. This mode is great to use on airplanes with the in-plane entertainment system or with sources that don’t have Bluetooth output. Unfortunately, and somewhat ironically, plugging in the cable introduces background noise.

There is consistent hissing as soon as you plug the cable in. It’s only audible when the cable is plugged in and the headphones are on and not present when you turn the headphones off. But as mentioned before, you are better off keeping the headphones on even when using with a cable so the presence of this background noise is rather annoying. It’s not very loud and only noticeable in quiet environments. In terms of latency, there is some latency here that is typical for wireless headphones.

When switching from wired headphones, you will notice a very minor delay when watching videos on the phone with these headphones but it’s very small and if you keep watching your brain adjusts itself after a few seconds to the point where you no longer notice it. I wouldn’t recommend these for gaming, however, as the latency can be disorienting in games even if it’s minor, and you never fully adjust to it. For music, obviously, there is no issue, whatsoever. Noise Cancellation The CH700N features active noise cancellation feature. However, it’s really not a strong feature of these headphones. The primary issue is with the design of the ear cups.
The ear cups use a relatively wide and shallow design. This makes the headphones comfortable to wear compared to other noise canceling headphones on the market but it makes the active noise canceling feature’s job harder. The ear pads are not particularly deep, which means they don’t seal your ears very well. There are small gaps left below your ears, which aren’t covered well by the shallow and thin padding on the ear cups.
It gets worse when you turn or tilt your head, which creates larger gaps that let outside sound in. To top it off, the active noise canceling feature itself isn’t particularly effective even under best-case scenarios. You get a fairly basic background noise suppression, which feels somewhat timid and underwhelming, even compared to rivals in this price range. When combined, it creates one of the least effective noise canceling effect I have tested.
It’s very dependent on your head shape and position, and slight shifts can cause a change in the background noise levels. Of course, any noise cancellation is better than no noise cancellation, and even at its worse, the CH700N are still a lot quieter than a standard pair of headphones and I’d pick these over standard headphones for a plane ride any day. However, considering noise cancellation is the big feature of these headphones, they don’t seem to be all that good at them. A small observation here; turning the noise canceling on or off is a somewhat lengthy process.
Turning it off incurs a 3.7 seconds pause while turning it back on takes 4.5 seconds. During this time you can’t hear your music playing in the background.
