Crutchfield Customer Review (What's this?)

Surprisingly comfortable and easy to wear at home. Ear hooks keep them in place and actually more secure than other IEMs I've used. Inline Cipher control is light enough not to pull on them. Cable is long enough. Sound quality is different from other IEMs and headphones. Amazing detail, clarity and soundstage. You will hear detail you didn't know was on songs you listened to for years. But, doesn't change or color the music beyond that. The factory EQ settings are very good, but I changed them slightly to get more high end sparkle and life. Some more background comes through on poor recordings, but overall it suits me better. So easy to make changes and compare to stock if on the iPad which shows both graphs. Using with iPod Touch 6h Gen mostly which only shows current settings. Volume is sufficient. Any louder wouldn't be safe for long term listening. Compared to IE800 and HD700/HD800, the isine20 is my choice now without any doubt. Not needing an amp makes it very convenient. Very good value too. All you need is an iPod Touch, iPhone or iPad. Also used with standard cable and Fiio E12 amp on iPod Nano7 and quite good. Cipher is best though. Don't dismiss these because they look funny - you will be amazed by the sound. Most IEMs sound good, but are prone to pulling out and needing constant adjustment. For me, the search is over, compared to currently available IEMs and headphones.

Pros: Fantastic sound with Cipher cable and App. More comfortable and wearable than it looks.

Cons: Open design not for noisy environments or flying. Won't work with iPod Nano.

Product Research


Overview: The Audeze iSINE is the world's first full-range in-ear planar magnetic headphone. The iSINE 20 comes with two 59" cables--one designed for use with Apple iPhone/iPad/iPod touch, and one universal cable. The headphones come with two pairs of ear hooks, two pairs of ear locks, an assortment of rubber ear tips, and a handy storage case.

Planar Magnetic Technology: The iSINE Series headphones are a miniaturized, in-ear version of Audeze's flagship LCD collection of planar magnetic over-ear headphones. The iSINE 20 features large (30mm) ultra-thin planar magnetic diaphragms with the patented Uniforce voice-coil technology and a single-sided Fluxor magnetic array for greater accuracy and clarity. The iSINE 20 has a longer Uniforce voice coil than the iSINE 10, providing greater coverage over the magnetic diaphragms, giving the driver better control, better bass and clarity, and improved imaging. Even at high volumes, the distortion (THD) is less that 0.1% overall.

CIPHER Cable: The iSINE 20 comes with the award-winning CIPHER Lightning cable, which is especially optimized for the iSINE series and for Apple mobile devices. The cable bypasses the iDevice's internal DAC/amplifier, and streams a 24-bit high resolution signal directly to the in-line module. The module is equipped with a high-quality in-line amplifier, a digital-to-analog converter, and DSP (digital signal processor), plus a 3-button remote and microphone. The CIPHER cable is compatible with iPhone 7, 7 Plus, 6, 6 Plus, 5s, 5c, 5, iPad Air 2, iPad Air, iPad mini 2/mini 3, iPad 4th generation, and iPod touch 5th/6th generation. A universal audio cable is also included for non-Apple devices.

Audeze App: With the accompanying Audeze app, you can take advantage of a 10-band EQ that lets you adjust the sound in real time. You can adjust the following bands by + or - 10dB: 32Hz, 64Hz, 125Hz, 250Hz, 500Hz, 1kHz, 2kHz, 4kHz, 8kHz, and 16kHz. You can save your favorite two EQ curves for later use, as they are stored in a non-volatile memory. The saved EQ curves can be used as you switch from one Apple device to another. The Audeze app requires iOS 8.1 or later, and is available for free download from the Apple iTunes App Store.

Fit: The iSINE 20 is designed to fit into the ear canal. It comes with three pairs (small, medium, large) of silicone ear tips to assure a correct fit. Two pairs (medium, large) of durable polymer Surefire EarLock retention rings comfortable lock the headphones into key points of your outer ear and keep them securely in your ear. There are also two pairs of ear hooks (black and translucent) that go behind the ear to hold the headphones in place. To keep the headphone cable in place, a clothing clip is included.

Why did you buy this?

Had a previous pair and loved them . Unfortunately someone else loved my computer and stole the along with my DAP, computer, IPAD and Kindle. I am replacing them because they are great. Actually bought the $2500 version and returned them as these sound awesome and are easier to drive. [ M  Aug 31, 2017 ]
They're the largest and open back earbuds available they'll be great for walking running and car rides, headphones are just too big for that, they're only really good for planes and maybe car rides. [ David  Aug 07, 2017 ]

1> Although the iSine20s are open back the noise is negligible as I also use mine in an office setting. 2>. The iSine20 doesn't include a microphone so I don't think you could conduct a Skype meeting with them on. 3> They aren't noise cancelling, you will hear external noise (which in my opinion is preferable when used in an office setting.
