Excerpt: This product is similar to Er4-pt, except the bass is a little stronger, and the highs are more emphasized. I returned this product because the vocals are receded, compared to my other headphones (sony xba-4ip, bose qc 15). I just can't get over with that. After 1 week of trying, I returned the product. Other than the vocals, the sound quality is phenomenal.
Pros: Comfortable, Compact, Durable, Great Sound, Lightweight
Excerpt: Not only do these little earbuds sound great, they are so so comfortable to wear. They are super light, and I use them for hours straight. I also find their modest physical design very appealing. These are not show off electronics.I listen to a variety of music; rock, jazz & classical. Everything sounds beautiful depending on how the music was recorded. The sound is open, detailed and fast. They are so light that I have stopped using my full size AKG 701s entirely.
Pros: Comfortable, Compact, Good Bass, Great Sound, Lightweight, Stylish
Excerpt: Grado is a grand old name in the audio industry. I've been buying their products for decades. With the GR10, the company outdoes itself. The music is pure, balanced, silky and open, with performers sounding as if they're only a few feet away. Conventional wisdom has it that in-ear phones can never rival the large over-the-air "cans." Grado has now reversed that conventional wisdom. Great product.
Pros: Comfortable, Compact, Durable, Excellent Stereo Effect, Good Bass, Great Sound, Lightweight
Conclusion: The GR10 I purchased from Sonic Electronix is my favorite earphone, and I have owned many, including Shure SE535, Sony EX1000, Westone 2, 3, UM3X, 4, 4R and the Etymotic ER4P. The GR10 (a moving armature) is a rare find in the crowded iem world. It has amazing clarity and is still musical w/ quality bass and amazing treble and lush mids. I believe it is the single best iem I've heard. While it lacks the weight/timber that the W4 has, the GR10 has a stunning clarity.
Summary: Gear used for testing: iPod Video 80gb (5th gen, Rockbox) + Fiio E17
Test tracks: "Survival" by Muse, "Take the Power Back" by Rage Against the Machine, "Finally Free" by Dream Theater, "Hessian Peel" by Opeth, "Sacred Worlds" by Blind Guardian
Sound quality and signature: Not transparent. Presentation is upfront.
Pros: They've managed to capture the Grado headphone sound with these little babies.
Cons: Isolation. The tips are kind of small "than they should be," at least for some people.
Summary: I am lost for words for 2 reasons, 1st: These in ears behave much more like over ears headphones in all the good ways.
2nd: these deserve to be much more popular than they are, I am simply shocked that there is not much more renowned!
I currently own the Shure SE535's as well as Sennheiser IE8 and have used and owned many of the 500 and under earphones, such as Monster Turbine Copper Pro and Etimotics.
Pros: Lots of space, instrument separation, depth, huge sound stage, highs that are not piercing(does not hit the wall of comfortable listening, so small
Cons: None for me, life is way too short to grumble about the price. It is cheaper than competing brands!
Conclusion: I really like how Grado kept the small design like they used on the GR8. Very lightweight and compact so they can really be used for anything! I've used the GR8 a few times and was impressed, but I heard Grado was working on a new model so I held out and kept using my Skull Candys... well worth the wait. I read they used an improved armature driver and its got a much lower impedance. Overall great balance!!!! Incredibly smooth!!!
Excerpt: When I bought a pair of GR8s for my girlfriend's ipod as a birthday present and saw her eyes light up, I knew that Grado was onto something special with their line of japanese-made in-ear monitors (IEMs). The deep soundstage, the ability to detect on even 128kbps MP3s bass and high trebles without shrillness or dropout, and the definition of each instrument was incredible, and I figured could not be exceeded by Grado. I was wrong. The GR10s do just that.
Pros: Comfortable, Don't Color Recordings, Good Bass, Lightweight, Neutral yet VERY defined
Summary: I have owned several earbuds including Shure 435's. To me these are the last word. Warm, engaging and never fatiguing. The bass notes are there without any painful thudding, the mid tones are spot on and you can here every detail. They sound great with all my files straight off my iPod Classic but to get the best out of them I have a Graham Slee voyager amp and a lot of my music is apple lossless, and it sounds unreal.
Summary: Best pair of balanced headphones I've bought. Wonderful clarity and as most of the other reviewers have highlighted, a natural sounding bass. Best in ear headphones I own (especially compared to the shure 535s) However, would say that the headphones were expensive for what they are.
