Lime Ears Model X 4BA CIEM

Lime Ears' second in line flagship utilizing not one but two most popular signatures, which can be easily changed with a flip of switch: choose either the “perfect neutral” or the “warm and musical” depending on how you feel today!

Acoustical design where one of the bores is tuned carefully in terms of length, diameter and volume. It provides numerous resonant effects that help even the frequency and impulse response of the transducers used in this design. PAR (Passive Acoustic Resonator) technology

Utilizing VariBore technology – Acoustical design utilizing sound bores of different diameter for each frequency band. Use of 2mm bore for high frequencies in combination with internal acoustical damping results in open sound and smooth highs. Vented double low-end driver delivers a juicy and powerful bass accompanied by extremely crispy highs produced by HF driver, with lush, distinctive mids placed perfectly in-between. With the switch positioned up, the sound becomes slightly warm and v-shaped. When you flip the switch down, your Model X turns into mid-to-high focused earphones which, thanks to vented construction, maintain the punch and clarity in the lowest end of the band.

Switch changes level of low frequencies (approx. 6dB<800Hz). You can also use it to make changes depending on:

1. The listening level - to make use of the Fletcher-Munson law (for lower listening levels, bass can be boosted to make it better audible)

2. The level and quality of bass in the recording (if the bass is well recorded, it can increase its strength. On the other hand, if the material is not properly mixed and lows are becoming boomy and get out of control, they can be trimmed down)

3. The external noise levels (if you are using your monitors in a noisy environment: airplane, subway, etc., where the low-end noise masks the lows, you might want to switch them up).
