The Pacific Ears (Ambient) Pentephon Monitor delivers a lush, articulate and balanced sound

The Pacific Ears (Ambient) Pentephon In-Ear Monitor delivers hard-hitting bass, smooth balanced mid and high-frequency response. Featuring our exclusive Sound Stage Imaging (SSI) technology, the Pacific Ears (Ambient) Pentephon delivers a lush, articulate and balanced sound with incredible depth and clarity. The heavy bass will be desirable for bass players, drummers, or those producing or mixing dance music and for audiophiles. This together with a precision tuned vent and filter to help cancel the occlusion effect and stay in touch with your performance environment.

If you are looking for an in-ear monitor with great bass dynamics and full spectrum sound quality, the Pacific Ears (Ambient) Pentephon is the one for you.

The Ambient Series. Custom fit vented IEMs with a professional specification just got a whole lot better!

Our Ambient IEMs offer the specification many musicians have been dreaming of for years:

  • Reduction of the occlusion effect you get with a custom fit IEM.
  • The ability to hear your environment around you whether on stage, in the studio or even on the street.
  • Stay in communication with your fellow musicians and hear off-mic cues on stage
  • Not feel isolated or removed from your performance environment.
  • Ear canal ventilation for reducing fatigue and providing greater comfort for longer.
  • Above all – a vented IEM that maintains 100% of the high-fidelity sound quality and low frequency response.
  • The Pacific Ears (Ambient) Pentephon In-ear monitors are packed with technology

We have introduced our patent-pending IRIS and exclusive SSI technology across our entire IEM line-up.

IRIS – Intelligent Resonance in Silicone is a patent-pending technology we have created to maximize the potential of miniature balanced armature speakers. IRIS construction methods allow for very precise acoustic tuning to deliver our unique sound signature. IRIS brings an added dimension to music in a way that mimics the warm, lush and open sound that valve amplifiers provide.
SSI – Sound Stage Imaging is a tuning technique achieved by using our own purpose-designed manifold technology. Implemented into our custom and universal in-earphones, SSI positions the audio into a wider array than other earphones, bringing a superbly defined and very detailed response to further enhance your listening experience, positioning all the instruments as if you were sitting in front of the stage listening to the live performance.

The Ambient Pacific Ears (Ambient) Pentephon IEM is the newest custom in-ear monitor. This 5 drivers IEM delivers deep hard-hitting bass, smooth balanced mids and crisp detailed sounds.

Pacific Ears (Ambient) Pentephon Monitors are fitted with the highest quality cables

The cable fitted to your monitors is of the highest quality. Manufactured to our own specification, each cable contains 80 strands of 100% oxygen-free copper, with each strand plated in pure silver. Aramid fibers (Kevlar) are woven into the twists to provide exceptional pulling strength and breaking strain. The sheathing on the cable is treated to dismiss harmful UV rays and will not discolor or oxidize like many other inferior cables. The design of the audio cable provides the best connectivity between your audio source and the earphones. When the cable is fitted in the lab it has optimum contact to the cable socket, therefore we strongly recommend that you don’t disconnect the cable unless it requires replacing.

The the Ambient Pentephon Monitors combine the latest technology

Combining the latest technologies and the new detachable cable system, the Pacific Ears (Ambient) Pentephon IEM delivers a huge sound, with great separation, wide soundstage and loads of headroom. If only the best will do then the Ambient Pentephon is perfect for you.

Ambient J-Penta Care and Maintenance

We make our in-ear monitors with pride and like all things worth having, they are worth looking after. Just follow these simple rules and you should receive many years of trouble-free service.

  • Check the sound ducts after each use and use the wire pick supplied to remove any ear wax that has made its way into the tubing.
  • Never use the cables to remove the IEMs – this will eventually put strain on the connector and will damage the cable.
  • Ensure moisture from either humidity or sweat is removed straight after use.
