## Features

- 【𝗗𝘂𝗮𝗹 𝗠𝗮𝗴𝗻𝗲𝘁𝗶𝗰 𝗖𝗶𝗿𝗰𝘂𝗶𝘁 & 𝗗𝘂𝗮𝗹 𝗖𝗮𝘃𝗶𝘁𝘆】KBEAR KS1 high resolution IEM in ear monitors are built around a 10mm PET diaphragm dynamic driver with dual magnetic circuit and dual cavity design: the independent back cavity compresses air instantly to boost power, while double magnetic flux over 1T lifts the electro-acoustic conversion rate and transient response for surging, detailed sound.
- 【𝗘𝘅𝗽𝗲𝗿𝘁 𝗧𝘂𝗻𝗶𝗻𝗴, 𝗕𝗮𝗹𝗮𝗻𝗰𝗲𝗱 𝗦𝗼𝘂𝗻𝗱】Tuned by an acoustic engineer with 20 years of experience, these wired earbuds deliver elastic, powerful low frequencies, warm and dense vocals and rich layering. 16 Ohm impedance with 109dB sensitivity makes this gaming earphone easy to drive by phone, tablet or laptop, no amplifier needed, and the balanced tuning suits vocal, rock and ACG for long daily listening.
- 【𝟰𝗴 𝗟𝗶𝗴𝗵𝘁𝘄𝗲𝗶𝗴𝗵𝘁, 𝗘𝗿𝗴𝗼𝗻𝗼𝗺𝗶𝗰 𝗙𝗶𝘁】The ergonomic in-ear headphone shell is shaped from massive ear canal data, weighing only 4g per side. The soft angle of the nozzle and front cavity fits the ear canal securely for long fatigue-free listening, with excellent passive noise isolation that keeps your music clean. Balanced pressure relief of front and rear cavities keeps the sound natural and flexible.
- 【𝗜𝗺𝗽𝗿𝗼𝘃𝗲𝗱 𝟮𝗽𝗶𝗻 𝗗𝗲𝘁𝗮𝗰𝗵𝗮𝗯𝗹𝗲 𝗖𝗮𝗯𝗹𝗲】A limit slot on the improved 2PIN 0.78 connector protects the pins from breaking and extends product life. The 4-core 4N pure copper cable boosts permeability for more textured bass and clearer vocals, so you can upgrade or replace the cable as you like. The standard 3.5mm plug fits phones, laptops, players and DACs right out of the box, plug and play.
- 【𝗘𝘅𝗰𝗹𝘂𝘀𝗶𝘃𝗲 𝗖𝗮𝘃𝗶𝘁𝘆 & 𝗨𝗩 𝗙𝗶𝗻𝗶𝘀𝗵】The fully enclosed high density PC cavity is molded at high temperature to suppress diffuse sound reflection inside the shell. Skin-friendly, simple and stylish with a UV varnish surface that shines like new, protected by the KBEAR exclusive molding appearance patent. Aluminum alloy sound guide mouth avoids resonance. Ideal IEM for stage, studio, sport and daily music, available in black,transparent and white.

## Questions & Answers

**Q: How long is the cord to these.?**
A: From earbuds down, about 3 1/2 feet. I'm 6'7", and when I wear them hidden down the back of my shirt they end up just below the waist like into my back pocket.

**Q: Can anyone tell me how much "bleed" there is from these? I want to keep my listening private too.**
A: Noone can hear the content of what your listening to. Also you dont hear outside noise. They are great

**Q: How do i contact this company with my order**
A: Links on the order page I think.

**Q: What kind of adapter should I get for these to this to work in my metronome that uses a 2.5mm jack? I'm confused by the "rings" on the various adapter**
A: I dont have my KBears in front of me but typically on the male (say in this case the end of the KBear cord ... what plugs into the device) you would see two rings ... i cant remember what order they typically are in but that is one ring for the left side and the other for the right side ... if these have 3 rings (or for anything that has the third ring) that third ring is related to the built in mic (for devices/headphones that have that feature), if i am not mistaken
