Get to know them!

Westone's W40s continue their line of audiophile-approved in-ear monitors, with a 4-driver/3-way design that delivers studio-quality neutral frequency response across an extended range. Dual low-frequency drivers join the discrete high- and mid-frequency drivers, bringing the low-end range all the way down to 10Hz for deep bass you can feel. To ensure you get a comfortable, personalized fit, W40s ship with a complete Fit Kit for both their Star silicone and True-fit foam tips. And in addition to their high-performance EPIC cable, you also get an MFi cable, which includes an in-line 3-button remote and microphone for your iOS or Android device.

True-fit universal design for comfort and isolation

Short of their Custom-fit personally molded earpieces, Westone's True-fit technology delivers the best acoustic seal and comfort Sweetwater has found in an in-ear monitor. Drawing on over 50 years of experience crafting earpieces for highly technical and medical applications, no one knows ear ergonomics like Westone. Coupled with their excellent eartips, the W40's low-profile and lightweight earpieces are so comfortable, you'll hardly feel them, yet they can easily block out up to 25dB of external sound.

Balanced-armature drivers offer comfort and detail

Unlike traditional earphones, which use moving-coil speakers, Westone's W40 features their innovative balanced-armature drivers. These remarkably compact and incredibly efficient transducers take up far less space than typical drivers, without losing the slightest bit of sonic detail. What's more, when it comes to multi-driver earphones such as the W40, the small size of these transducers allows the earpieces to seal well and sit comfortably in your ears while providing superior isolation.

Replaceable EPIC cable extends earphone life

If you've ever owned a pair of high-end earphones that were rendered useless because of a damaged cable, then you know how frustrating that can be. Westone completely eliminates that issue with their removable EPIC (Earphone Precision Interface Cable) cable, which is easy to replace by hand. And you'll probably never need to replace your EPIC cable, thanks to the durable braided outer layer and aramid fiber reinforcement protecting its flexible, ultra-low-resistance tinsel wire.

Bonus MFi cable with a 3-button remote/mic

Once you mix or perform with your Westone in-ear monitors, you won't want to go back to your regular earbuds. Swap out the EPIC cable with this bonus 52" MFi cable, which includes a 3-button remote and microphone. The universal TRRS connector ensures that it's compatible with iOS and Android devices.

Complete accessory package included

Find the perfect fit, with a full set of eartips. This included fit kit comes with every size of both True-fit foam tips and Star silicone tips. You can customize the look of your earpieces with three interchangeable faceplates. Pro tip: use two different colors to make it super easy to tell the left and right sides apart. A Wax Loop lets you keep your in-ears clean, and you can protect them in the included Mini Monitor Vault.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown.
