ProStereo™ L5 Stereo Bluetooth Headset Cable, the Most Complete Wireless Audio Solution For Professional Headsets

4 May 2017

Since 2016, i.Tech has committed to expanding in the audio equipment sector. ProStereo™, a side-line series, has made a name for itself among high-definition headsets in the market. In the new year, the series will present itself in a brand new look, providing users with professional as well as diverse choices of mobile audio products.

As headsets with MMCX connector get more popular, ProStereo™ has developed the latest ProStereo™ L5 stereo Bluetooth headset cable for users to convert personal MMCX headset into a convenient Bluetooth headset to maximize flexibility of the device.

Sound Quality Comes First: Blending aptX™&, AAC Decoding and Silver-Plated 4N Oxygen-Free Copper Wire

Leveraging Qualcomm’s version 4.1 Bluetooth chip, ProStereo™ L5 has SBC, aptX™& and AAC codecs built into its device, which allows transmission of audio signals with almost no distortion, whether users listen to songs using Android~ phone or iPhone. ProStereo™ L5 delivers unmatched price-performance value, employing silver-plated 4N oxygen-free copper audio cable with the highest electrical conductivity that can fully bring out the inner potentials of the headset.

The native balanced audio jack not only eliminates the effect of outside interference on audio signals, but also reduces the mutual interference between the left and right sound channels caused by the ground wire, thereby greatly enhances separation and brings about an enhanced musical experience with every fine and delicate musical nuance.

IPX4 Splash-Proof Design

To enrich user experience, the ProStereo™ L5 adopts a splash-proof hardware design which can stand the rigorous IPX4 test. Rain, sweat, or even splashes of drinking water will not affect the headset’s operation.

Adjust Different Sound Effects Freely With Built-In EQ Equalizer

One characteristics of the ProStereo™ brand is that it provides different solutions for enjoying music. The simplistic design of ProStereo™ L5 should not be underestimated, for it has a built-in EQ equalizer with which users can tune to four sound play modes: “Normal”, “Bass”, “Jazz” and “Rock” by simply pressing the “Volume +” and the “MFB” buttons at the same time.

Clear And Smooth Voice Call Empowered By High-Standard MEMS Microphone With Three-Button Wired Control

To be the most complete wireless solution, ProStereo™ L5 makes sure to take care of users’ need for voice call. It uses a high-standard MEMS microphone, making sound reception clearer and more outstanding. The product’s three-button wired control enables easy operation for music play, calls and voice-prompt functions. In addition, ProStereo™ L5’s built-in battery can support up to 5 hours of wireless music play and call, adding extra value to users’ own personal headset.
