Answers to the questions Shure SRH840, SRH940, SRH440 and SRH750DJ owners ask before buying a braided replacement cable with a 6.35mm adapter.

Which Shure models does this cable fit?

Will this cable work with my Shure SRH840 headphones?: Yes. The Brainwavz replacement cable is listed as compatible with Shure SRH840, SRH940, SRH440 and SRH750DJ headphones. It is a third-party compatible product made by Brainwavz, not a Shure original part.
Does the same cable fit the SRH940, SRH440 and SRH750DJ?: Yes. The same cable is listed for all four models: SRH840, SRH940, SRH440 and SRH750DJ. You do not need a different version for each headphone.
Is this a genuine Shure cable?: No. It is a third-party compatible replacement made by Brainwavz. That matters if you want an exact original part, but it does not change the listed headphone compatibility.

What connectors does the cable have?: The cable has a 3.5mm audio jack plug for media devices and a 2.5mm audio jack plug for the headphones. Both connectors are gold plated.
Can I plug it into a laptop, phone or tablet?: Yes. The 3.5mm end is designed for mobile phones, tablets, laptops and computers. You connect the 2.5mm end to the headphones.
Does it work with audio equipment that has a larger socket?: A 3.5mm to 6.35mm screw-on adapter is included. Use it when your audio equipment has a larger connection socket than the 3.5mm plug.
Do I need to buy the 6.35mm adapter separately?: No. The adapter is included with the cable, so you do not need a separate purchase for larger sockets.

How long is the cable?: It is 1.5 metres, which is also listed as 150cm or 4.9ft.
Is 1.5 metres long enough for desktop use?: It depends on where your audio source sits. Measure the distance from your headphone jack to your laptop, interface or phone before ordering. The supplied information gives the cable length but does not recommend a maximum distance or setup.
What does the braided construction mean in practice?: The cable has an extra strong woven construction designed for durability and to withstand wear and tear. It is also described as tangle-free for hassle-free use and a longer lifespan. These are manufacturer descriptions, not independently tested results.
Will this cable change how my headphones sound?: The supplied information describes the gold-plated connectors as being for crystal-clear sound, but it does not demonstrate an audible improvement over another cable. Treat that as a manufacturer claim rather than a guaranteed change in sound.
