About the Audeze LCDi3 in-ear headphones

The world's first wireless planar magnetic earbuds

Audeze's LCDi3 headphones are their first set of in-ear monitors (IEMs) that can play music wirelessly from your phone. That's a big deal to those of us who are spoiled by the convenience of Bluetooth — but love Audeze's spacious, detailed sound. They've shrunk their cutting-edge planar magnetic drivers into a compact in-ear design and created a Bluetooth adapter cable powerful enough to drive them.

The world's first wireless planar magnetic earbuds

Audeze's LCDi3 headphones are their first set of in-ear monitors (IEMs) that can play music wirelessly from your phone. That's a big deal to those of us who are spoiled by the convenience of Bluetooth — but love Audeze's spacious, detailed sound. They've shrunk their cutting-edge planar magnetic drivers into a compact in-ear design and created a Bluetooth adapter cable powerful enough to drive them.

This wireless adapter connects the left and right ear pieces and sits behind your head during use. It includes Bluetooth 5.0 — the strongest, most-reliable Bluetooth yet. It also features aptX HD® technology for improved sound quality with devices that support this advanced wireless audio codec. 

Two cable options for multiple uses 

Along with the wireless Bluetooth adapter, Audeze includes a wired option terminated with a traditional 3.5mm miniplug. This works well for connecting to a phone that still has a minijack, but also a portable high-res player or portable headphone amp/DAC

Listening impressions: I heard crystal clear, wide-open sound

I auditioned the LCDi3s with the Bluetooth adapter first. The idea that I could listen to Audeze IEMs wirelessly was too exciting to pass up. Connection to my Samsung Galaxy phone was quick and the in-line remote/mic had raised buttons that were easy to find behind me.

The remote is on one side of the cable and a module housing the Bluetooth and audio circuitry is on the other. These modules were a little bulkier than the ones you find on more traditional wireless headphones, but the weight was distributed in a way that I didn't really notice. Audeze includes some ear hooks that took me a few tries to master, but really help keep the earbuds in place. 

Listening with the Bluetooth adapter

As expected, the sound is transparent, and the highs have real sparkle. It was a neutral tuning that sounded clean, but not clinical. Bass was realistic and finely detailed, yet not overly emphasized.

"Keep on Growing" by Derek and the Dominoes really played to these headphones strength. This delightful jam session occupied every bit of the "outside-the-head" soundstage, with the bass line off to the left, keyboard to the right, vocals dead center, and the three lead guitars coming from all directions. And the percussion really lept out at me. On IEMs with a more condensed soundstage, the track can sound conjested — but through the spacious LCDi3s, it was pure fun. 

A separate headphone amp for added punch

When listening to certain hip-hop tracks wirelessly, I was a little underwhelmed by the low end. I'll admit, I auditioned these IEMs after testing some less sophisticated, bass-heavy 'phones. So maybe I was too accustomed to the artificial "boom." 

But then I connected these headphones to the powerful, portable iFi Audio hip-dac and fired up Quboz on my laptop. Listening to a CD-quality stream of "Hot Damn" by the Clipse, I definitely heard some extra bass knock for the classic Neptunes production. And when I pressed the hip-dac's "Xbass" button, it lifted the sub-bass significantly without distorting or overbearing the rest of the track. 

Planar-magnetic drivers: the basics

So how do planar magnetic headphones usually work? A large yet ultra-thin diaphragm is suspended within a magnetic field. It is covered with a flexible circuit. When the circuit receives an audio signal, the diaphragm moves back and forth to create sound. It starts and stops rapidly for clean and accurate sound across a wide frequency range.

How did Audeze fit that technology into an earbud?

The diaphragms used in the LCDi3 are a fraction of the size used in most planar magnetic 'phones. Still, you can probably tell from the pictures that these headphones are bigger than most in-ear models. You stick the earbuds in your ears while the planar drivers actually sit outside.

To make up for the loss in diaphragm size, Audeze uses their super-powerful Fluxor magnets to provide quicker movement. These magnets are nearly double the power of a traditional magnet, making the LCDi3 drivers incredibly efficient.

Product Research


Overview: The Audeze LCDi3 in-ear headphones feature the same design as the award-winning LCDi4, but with the lower impedance of the iSINE series. The LCDi3's Planar Magnetic transducers give you audiophile sound from any device, including your smartphone, tablet, or portable digital music player. The headphones come with a standard cable with a 3.5mm plug, and Audeze's CIPHER Bluetooth module for wireless listening. Also included are four pairs of ear hooks and a pair of ear fins for a secure fit, an assortment of silicone rubber ear tips, and a handy travel case.

The LCDi3 features large 30mm (1-3/16") transducers with ultra-thin Uniforce diaphragms and a Fluxor magnet array with N50 neodymium magnets. Each unit is hand-assembled at Audeze's facility in California, and the drivers are matched to within +/- 1dB of each other. The headphones deliver a wide, accurate soundstage and superior transient response.

CIPHER Bluetooth Module: For wireless listening, Audeze includes the CIPHER Bluetooth module. The module features Bluetooth 5.0 support with aptX and aptX HD, and Audeze's proprietary DSP to optimize the sound for wireless listening. With the LCDi3s connected to the CIPHER Bluetooth module, you'll enjoy high-quality 24-bit wireless audio from your favorite device. The CIPHER Bluetooth module's 3-button remote works with iOS and Android devices. Functions include power, Bluetooth pairing, play/pause, next/previous track, volume up/down, answer/end call, reject call, switch calls, and voice assistant. The CIPHER Bluetooth Module has a rechargeable battery with a USB charging cable.

Cable: The LCDi3 includes a 58" auxiliary cable is included with a straight 3.5mm plug, but no remote/microphone.

Fit: The LCDi3 is designed to fit into the ear canal. It comes with three pairs (small, medium, large) of silicone ear tips, and three pairs of Groovy Spiral Eartips made of silicone. The package includes four pairs of ear hooks that curve inward along the back of the ear to ensure a secure fit.

Customer Q&A

2 questions already asked

How loud is the sound leakage from the open-back design? would it bother someone in a plane seat next to me? How about 3 ft away in the living room?
[ Kelly  Jul 05, 2022 ]
1 answer
There is no way we will be able to gauge what will bother folks or not, Kelly. We can say that since these are an open back design there will be some sound leakage, of course. Whether or not you are running these on a small headphone amp, or with the Bluetooth adapter will affect that as well. Usually the leakage is not too bad, most likely only becoming problematic in very close quarters and quiet environments. I'd say it is worth it for the spacious sound field these Audeze LCDi3 deliver, that's for sure!

Hello, does this include the iPhone FireWire cable as well?
[ Kencarlson  Sep 16, 2021 ]
2 answers
Ken, my understanding is that the FireWire from Apple is actually a computer based system and has never been used with iPhones in the past. However the connector that Apple uses with the iPhone is called the Lightning Connector. This is included with this headphone. You will get three main cables with this purchase, the first is a standard headphone jack cable(classic tried and true), the second is a Bluetooth cable (this sits behind your neck with two cylinders that allow for the Bluetooth battery and equipment necessary to connect to Bluetooth devices, Last but certainly not least and my overall preferred way to use these earbuds is with the Lightning cable attached directly to my phone. The lightning cable Audeze created for this set of earbuds is purpose built to drive them from an iPhone or other lightning device and contains an in cable DAC/Amp that sends power from the phone over to the earbud drivers. I find this option to be the best audio quality possible from these earbuds and I highly recommend it.

No it doesn't.
