From the manufacturer

W Series

The 'W' Series is specifically designed for optimized personal listening, because Westone believes that music lovers should hear what the artist and producer intended when they listen to an artist's recording. Each W Series earphone contains from one to eight drivers, depending on the model, for the absolute best sensory listening experience imaginable. The patented ear tips use an ergonomic design incorporating lessons learned on fit and design gathered over the last five decades of manufacturing millions of products for the human ear. Along with providing extreme comfort, the ear tips isolate ambient noise to provide the utmost clarity.

Choose From W10, W20, W30 or W40

Using a unique single balanced armature driver, the W10 is a universal-fit in-ear monitor that is tuned specifically for listening to mastered, recorded music. It is a great first-level option and a perfect upgrade to unlock the potential of your music device. The W10 uses the same advanced technology found in Westone's iconic ES Series and delivers extraordinary detail.

A true dual-driver in-ear monitor tuned for listening to mastered, recorded music, the W20 is the world's smallest dual driver design. A separate bass and high frequency balanced armature drivers enhance your listening experience with incredible detail and dynamics.

With a triple driver design, the W30 uses separate bass, mid-range and high frequency balanced armature drivers in conjunction with an advanced 3-way crossover for a truly awesome personal listening experience. Based on the W3, the world's first universal-fit 3-way, 3-driver earpiece, the W30 has been redesigned to provide extraordinary quality sound and exceptional comfort from our silicone or foam ear tips.

The Westone W40 Quad-Driver in-ear headphone will take your listening experience to an entirely new level. Four balanced armature drivers and a 3-way crossover network deliver breathtaking clarity and realism. Westone's ear tip technology provides superior ergonomics and comfort. Westone's 50+ years of experience with in-ear applications has yielded a low-profile, lightweight, universal earpiece which delivers maximum comfort and in-ear coupling for dynamic transfer of sound. Westone's balanced armature drivers are significantly more compact and efficient than traditional dynamic drivers. By combining multiple balanced armature drivers with sophisticated crossover networks, Westone earphones provide enhanced sonic detail and a frequency range that extends well beyond typical in-ear solutions.

All W-Series Earphones Include:

  • Five sizes of patented star silicone ear tips
  • Five sizes of premium True-Fit comfort foam ear tips
  • MFi cable and Westone 3.5 mm braided replacement cable
  • Mini-monitor vault
  • Cleaning tool
  • 2-year warranty
  • Replacement Android cable is available separately

Today, Westone has expanded its in-ear product line to provide unparalleled sound quality for all on-stage musicians, as well as for casual listeners who want a high-fidelity sound experience.

Westone Story

Established in 1959 as a custom-fit earpiece manufacturer, Westone has become known worldwide as 'The In-Ear Experts.' From its roots of working with hearing health professionals to produce custom-fit products for hearing aids and protection, Westone has expanded into offering consumer audio products and is the world's premier designer of high performance in-ear musicians' monitors and earphones.

Westone became a master of audio technology as the result of requests from popular rock musicians in the early 1990s. They wanted the ability to hear specific instruments or vocals while on stage yet reduce overall stage volume to protect their hearing. As a solution, Westone created the first balanced armature driver in-ear monitor that became the standard for professional musicians.

    Product Description

    The Quad-Driver Westone W40 in-ear headphone will take your listening experience to an entirely new level. Four balanced armature drivers and a three-way crossover network deliver breathtaking clarity and realism. Westone’s True-Fit technology provides superior ergonomics and comfort. Westone's 50+ years of experience with in-ear applications has yielded a low-profile, lightweight, universal earpiece which delivers maximum comfort and in-ear coupling for dynamic transfer of sound. A replaceable cable connection includes the braided EPIC cable and round MFi cable with 3-button Apple Control System and mic function, including volume +/- , tracking +/- , phone answer, and Siri activation. Westone's balanced armature drivers are significantly more compact and efficient than traditional dynamic drivers. By combining multiple balanced armature drivers with sophisticated crossover networks, Westone earphones provide enhanced sonic detail and a frequency range that extends well beyond typical in-ear solutions. Exchangeable black, blue and red color faceplates are included with secure attachment. Each set of W40 earphones comes with an EPIC replaceable cable and MFi G2 cable, premium comfort tips, mini-monitor vault, cleaning tool, and 2-year warranty. The Mini Monitor Vault is constructed of a high-impact polymer and is the perfect size for travel and storage. It features a protective foam interior and weather resistant design. The Westone W40s are ideal for classic and hard rock, heavy metal, alternative, classical, vocal, jazz, and acoustic music, delivering stunning audio in a quad-driver design. Make sure you try all the eartips provided to find the correct fit and comfort for you. If the eartip is too small and doesn’t create a complete seal inside your ear canal you will lose low end frequencies. Choose the largest tip that is still comfortable for you. You may even need a different size tip for each ear. Make sure the right earpiece is worn on the right ear and the left earpiece on the left ear. The earpieces are marked, and when worn the cable should point to your front and wrap around to the back of your ear.

    Westone W40's
    I don't like the fact that Amazon groups the W series together like they do for review purposes. So let's be clear, I am writing about the W40's and my experience with them. I've had these for about six months at the time of this review. For reference, I primarily use these with the Fiio X7 music player and occasionally at work with a Samsung S7 Edge. I listen to both losses music files on SD cards and lossless streaming with Tidal. I will say right off the bat that there is a night and day difference between the two sources with the X7 being far better as a music player. But, that's all it does so I would expect that to be the case. The W40's are a little bit more difficult to drive from a power standpoint than say a 30 or 40 dollar pair of iem's from the local store. Don't get me wrong...They work just fine with your phone or tablet, but they seem to improve a lot when a good power source is thrown in the mix.Out of the box they come with a hard case and it's nice enough, but I find it a pain trying to stuff the cord in there to close it and don't really find myself using it. Also, two cables are provided and one includes inline phone controls and I believe a mic. I don't use that cable so I can't really speak to it. These come with a huge assortment of ear tips (silicone and foam) and remarkably not one worked for me. What did work for me was the triple flange tips that Shure makes for their products. The nozzles are the same so they are (for the most part) interchangeable. That said, expect that if this is your first time with Westone, Shure, or similar...you will find inserting these and getting used to having them in your ears a bit of a thing. It's different than others, but well worth it in the end because once you get used to it the seal is superior and they don't move or get in the way.Sound is very balanced I would say. There is a small bump in bass over what I would consider a flat response. They certainly are not beats by Dre with a ridiculously boosted bottom end. Without entering into the endless debate of burn in; I will say that my perception has been that they have gotten better with time. This has been most noticeable in the treble where I felt they were a bit muddy or veiled sounding out of the box. Today they sound remarkable and I'm very happy with the purchase. Treble and mids are now on point and they resolve detail very well. Bass is big but it's quite controlled. I expect this has something to do with having four discrete drivers. Regardless, they sound great and with a good source they sound even better.Quality has been really great, although I haven't had them for very long. I haven't had an issue of any kind and they get pretty roughed up at work as I am a mechanic by trade. I've never actually switched to or used the cable that has the phone controls inline so the connectors for the removable cables haven't been stress tested. The cable has been caught numerous times on equipment and pulled so hard it disconnected from the earpiece but it always popped back in and worked again as advertised.In conclusion I would say there is little (if anything) for me to complain about. I'd buy them again 10 out of 10 times. They sound great, seem to be pretty tough, and come with a lot of options. If music is important enough to you to justify this price tag, I would say buy them. If you can run them off a good dac and/or headphone amp...you will love them even more.

    Reviewed in Canada on April 3, 2016
    This is an awesome earphone and I was able to get such a nice deal that I can't almost believe it!

    Everything looks and sound premium (these retails in the 500.00-700.00 range). Package comes in a nice Westone box where the earphones site in a nice foam crate. The orange box contains multiple tips (foam and Westone latex high quality). I personally use and kept on the medium foam tips. Nice isolation and sound balance. I really like both cable but I also use the nice twisted one. Feels solid (even though it's not huge) and it does not tangle easily + stays put behind my ears.
    Comfort is great, excellent. I prefer it over the Shure SE215 and Westone 1, for example. The housings are slightly smaller than these and they are perfect for me. They stay in ear and keep in place.
    Earphones build feels solid overall. And they came with the red and blue plates, which is a very nice touch. Other plate (red, blue and black) are available with the appropriate tool if I want to modify the look. Nice solid classy touch to tthe iem.

    The sound? Wow. The precision. I like my stuff with a good bass and a lot of details. So far, Ostry KC06A were my go to earphones, but it seems they were beaten. W40 does not have a strong mid bass but everything is so well defined. Bass is well balanced and present. Just enough to like it, but way leaner than most low price earphones. Mids and vocals are totally awesome. Details and color are up there. High quality. HIghs are really, but really good. Well defined, no sibilance or harshness at all. It's my first step in the high end, I am totally satisfied. Soundstage and separation is very good also. Male or female voice can be heard in so much details! Whispers, breaths, you hear everything.

    I personally listened (and still listening) to a lot of headphones/earphones and I am not the one to say that I hear new things in my recordings all the time. Yes, most of the products have their signature and I have fun listening to my very long playlist with them. But these Westone W40 are really a new beast for me and yes, I am discovering new things in songs I have listened many times before with other earphones.

    They are that good.
