NEW NEOMUSICIA Replacement Cable Compatible with Hifiman HE4XX, HE-400i (The Latest Version with Both 3.5mm Plug) Headphones 3.5mm / 6.35mm to Dual 3.5mm Jack Male Cord 1.2m/4ft

Had to replace my expensive supposedly heavy duty Periapt cables that broke down. So far i don't see any issue outside of the lenght which is a bit shorter than i expected. 1ft more would have been ideal but oh well. They sound great, the connectors aren't lose and the there is a stress relief spring on them.

One of the best upgrades we can do as audio enthusiasts, audiophiles, etc. is to simply upgrade the cable. That is the case here for me with my Drop Hifiman HE-400XX planers. The imaging from planar magnetic headphones is something everyone should experience at some point in their life. Its a very moving, moody, accurate sound leaning slightly on the warm side. Ive never heard miss reproduced like planar magnetics are capable of. I can literally drift off in to the music experiencing very little note and nuance the composer intended. Fascinating in a way that make them truly incomparable to anything close. Yes of course there are various grades of headphones with varying price points as well. The concept however, is the same. Planar magnetic drivers mix some of the operating principles between dynamic and electrostatic drivers. In a planar magnetic setup, the part that actually creates sound is an electrostatic-style thin, flexible material sandwiched between the outer layers of the mechanism. But like a dynamic driver, that diaphragm contains extremely thin wires with electrical current flowing through it, which regulates its back-and-forth vibration.On to the NEO MUSICA upgrade cable...its a real winner. The material is perfect, the leads are very well produced providing an even better sound than the stock cable. In order to notice this however, you will have to lived with the stock cable for a while so you can draw the comparison. Everything is just so much more "alive" is how I would put it. The details are not so that it does not work hi or low, it just works better. The sound is more engaging and coherent leading to a dramatic listen no matter what the content. In its simplest terms, hi-res audio tends to refer to music files that have a higher sampling frequency and/or bit depth than CD, which is specified at 16-bit/44.1kHz. Sampling frequency (or sample rate) refers to the number of times samples of the signal are taken per second during the analogue-to-digital conversion process. The more bits there are, the more accurately the signal can be measured in the first instance, so going 16bit to 24bit can deliver a noticeable leap in quality. Hi-res audio files usually use a sampling frequency of 96kHz or 192kHz at 24bit. You can also have 88.2kHz and 176.4kHz files too.I just love getting lost in the whole of it. My mind is peaceful. There is also a certain peacefulness in knowing you are not literally missing a beat! This cable provides sonic bliss for those looking to achieve that. For others, there may be no justification in a "better" cable. Like I mentioned earlier, to really appreciate the sonic qualities living with the stock cable for at lease 3 to 6 months is best. It is then that you can draw your own comparisons between the two. Enjoy!

1 unit sounded like god, 1 unit sounded potato. Possible unit variance? The one that sounded like god picked up background information really well. The background information was clear and nuanced. It makes the chain sound resolving (just cheapy phone -> cable -> 4XX). Cables alone have a large impact on the sound. Stock is made of mud for instance. Cables that have seen wear (these ones - I have 3 of these total) do also reduce quality, even if it doesn't obviously sound like it.

Great cable, significantly better than the stock hifiman cable that came with mt sundara headphones. Durable and lays flat and the connections seem solid. Excellent value.

So a bit of a story, but I have a pair of headphones by grado labs. While I absolutely love them, the cable on them is complete garbage and broke within 3 months. I opened them up, soldered in some connectors, and plugged these bad boys in. They were relatively easy to get working and the cable quality is leagues better than what came with my grados.
