Grado GW100 Review

When I first opened the box containing the Grado Labs GW100 headphones, one word came to mind: “Cheap”. The cans didn’t look or feel like the classy Grado RS1i and RS1e, which I once owned, or the GS1000e that are still beloved and possessed. But after connecting to Google Pixel 2 XL (and later the 3 XL), via Bluetooth, I exclaimed: “Priceless”. The first offering in the company’s “Wireless Series” rises to an audiophile class unmatched by most competing cans; I prefer the GW100 to the GS1000e, which cost four times more to buy. Four words best describe the experience listening to music of any genre: Natural. ImmersiveBalanced. Authentic.

The GW100 are unique among wireless headphones by design: They are open-back like Grado’s wired models, but they are unlike all other major manufacturers’ wireless cans, which typically cover the ears and/or impose oppressively confining noise cancellation. I understand that commuters on noisy trains or travelers on rumbling airplanes might want NC, but the feature creates a cone of silence that is very unnatural. By comparison, the GW100’s open-air design allows music to expand, while—I must concede—letting in background noise going on about you. 

Quality Where It Matters
For my testing, I streamed 1411 kbps FLAC (Free Lossless Audio Codec) from Tidal. I would describe the aural quality connected to the Pixel 2 XL as bright and punchy. Later, in Android Pie Developer Options, I manually switched from System Default to aptX audio and the change drew out the highs and lows, and balance between them, while increasing detail and ever-so-slightly the timbre. Whether bug or by design, Android 9 returns to default settings when the headphones disconnect, requiring manual change when reconnecting. It’s a nuisance task worth the trouble.

Instruments obscured by other headphones are revealed by these cans, which exceptionally expose detail, such as vocal nuances or tap of drum cymbals. Spectacular soundstage, bright highs, and warm mids are defining acoustic characteristics. Open-back headphones typically give the most realistic soundstage. I would describe the aural quality as airy, although the GW100 are more contained than the aforementioned other Grados. That quality makes them the better choice for modern genres like dance, pop, punk, rap, or rock. Bass also is more pronounced but nowhere oppressive. Buyers wanting thumping lows should look to Beats or Sony, instead.

The GW100 also are more balanced than the other Grados, and that’s an achievement of significance compared to other wireless headphones that use over-ear designs or noise cancellation to create a sense of isolation. The GW100 give a more contained, yet generously spacious, sound even while letting in ambient noise. BTW, these cans give classy soundstage while warning of danger when used for work or play (gasp, on bicycle or scooter rides), because you can hear what’s going on around you.

Low impedance means the GW100 produce plenty of volume from portable devices like laptops and smartphones, without need of a digital amplifier. But to reiterate, sound source matters. CD audio or lossless digital streamed from a supporting aptX device improves soundstage and detail. That said, the overall tonal quality still pleases, but with punchier and bassier characteristics, without aptX.

Some specs:

  • Style: Open-back
  • Impedance: 32 ohm
  • Bluetooth: 4.2 with aptX
  • Transducer: Dynamic, open air
  • Frequency response: 20-20,000 Hz
  • Battery: 320 mAH (rated 15 hours at 50-percent volume)

Feel and Functions
To be fair, my initial “cheap” reaction is unfair to Grado. My past experience with wooden enclosures from the company’s RS and GS series raised expectations. That said, the GW100 are made of plastic and metal that doesn’t look, or feel, anywhere as classy as the sound. Controls, on the left earpiece enclosure, are plasticky to the eyes and to the fingers. The earpads appear unimpressive, although they are super comfy such that the cans can be worn for hours without earlobe discomfort. By contrast, wooden Grados sound fabulous but quickly feel uncomfortable to wear. The lower-cost, wireless model makes no such unpleasant demands of your sensitive cartilage.

While the GW100 are distinctive for looking like no other wireless headphones, they don’t feel all that rugged. How well they hold up will be the test of time. By contrast, the Master & Dynamic MW60 sport an iconic design that is solid; long-lasting. They do cost three-hundred bucks more ($549 vs $249). But in the looks can be deceiving department, I greatly prefer the GW100’s spacious soundstage and authentic audio to the MW60’s more synthetic sound. Both have their place, and your tastes may differ from mine.

Functionality is barebones. The GW100 connect to one device at a time, offer no extra frills like adjustable equalizer, and rely on three buttons for power and volume. That said, there is something about the understated approach that keeps away distractions that can detract from what matters: The pure sound. Sure you could change the output by, say, using Android’s Audio Effects feature. But that defeats the reason for buying Grados: The distinctive, airy, authentic sound signature. Sometimes less is so much more.

Wireless range is adequate but nothing like the best-in-class distances achieved by the MW60. I generally keep my phone in the same room as the Grados. Battery life easily exceeds the promised 15 hours.

For $249, the GW100 are an exceptional value. The listening experience is pure delight. That characteristic matters much more than any of my design material misgivings—qualifying that the cans could be considerably more rugged than they appear or feel. Time will tell.

If you’re looking for superior sound, with luscious detail, in a wireless headphone—and don’t mind letting the world around you seep in—look no further than the Grado GW100. I ordered mine, direct from the company, on Oct. 12, 2018 and love them. My GS1000e and MW60 collect dust now.

Useful Jargon
Some important technical tips for headphone shopping:

  • Soundstage is how instruments are spatially placed in audio recordings. The GW100 present surprisingly superior soundstage, such that you often can visually place the instruments and singers, and even feel like you are in the room with them.
  • Open-back headphones let in the most background noise or leak sound to those people nearby. However, Grado claims leakage is as much as 60 percent less “compared to our wired headphones”—something my informal testing confirms. Open-backs also typically present the best soundstage of headphone styles. Think spacious, as in concert hall, rather than confined (such as inside a studio).
  • On-ear headphones are as named. They sit on the lobes rather than enclose them. Whether or not as comfortable as, or more than, over-ear is a matter of taste. Without active noise-cancellation, like open-back, the wearer will hear sounds in the room.
  • Over-ear headphones typically cover the ear, making a soft seal that improves the aural experience while blocking out most background noise. Many people find this style to be the most comfortable to wear, particularly for long periods of time.
  • Impedance is a value you need to worry about. We’ll skip the science and get to practical matters: If you’re buying cans to listen to portable devices, like smartphones or PCs, you want lower impedance; I find 32 ohm—what the GW100 deliver—to be just right. If impedance is too high, you won’t jack enough volume to your headphones without aid of an amplifier. For stereo systems you want higher impedance, upwards of 600 ohm.
  • Frequency response typically ranges from 20 to 20,000 Hz, with bass and treble at both ends, respectively. The extremes exceed normal human hearing range, but not necessarily perception: Below 20 Hz, the listener may more feel the bass than hear it. GW100 offer the typical, ample range.
  • Transducer creates the sound, and there are typically three types: Dynamic (most common); Orthodynamic; and Electrostatic. Think little speakers. See Headfonics’ explanation for more. GW100 are dynamic.
  • Active noise-cancellation uses microphones to capture and largely eliminate ambient, background noise. For the record, I recommend headphones without this feature, which interferes with overall audio quality.
  • aptX codec allows for wireless delivery of high-fidelity music via Bluetooth without imposing heavy compression. Google, HTC,  Huawei, LG, OnePlus, Samsung, and Sony are among the major brands broadly supporting aptX across their smartphone lineups. Notably missing: Apple. Full list of supported devices.


I shot the Featured Image and its two companions, using Leica Q by manually focusing in Macro mode. Vitals for the first two, aperture manually set: f/2.8, ISO 100, 1/160 sec, 28mm; Dec. 27, 2018, 3 p.m. PST. The third is the same but 1/200 sec.
