What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

Introducing DRUM by TUNAI Creative, the High-Resolution Bass Enhanced Audiophile Earphone. DRUM is engineered to deliver well-rounded sound throughout the audio spectrum, including clear, high-end, rich mid-range, and powerful bass. It gets you as close to perfect sound as our environment permits. DRUM by TUNAI is all about the sound quality, and the sound experience you’ve been waiting for.

 

 

 

High-Resolution Audio 

DRUM is designed to meet the latest high-quality audio standards established by Japan Audio Society (JAS). It’s also the great combination of performance, features and value.

Large Diameter Drivers  

The rich sound common to many instruments and vocals can be found on the low end of the sound spectrum, but in order to maintain a balance, most in-ear headphone designs use a small-to-medium driver. DRUM has been modified to a larger 13mm dynamic driver for richer, more powerful bass and wider soundstage.


Ultra-Thin PET Diaphragm

 With DRUM, you get an ultra-thin speaker diaphragm constructed from 8 μm aerospace quality PET, facilitating lightning-fast response times in the speakers and extend frequency range to 40,000Hz. It provides performance exceeding the requirements of digital audio sources.

Oxygen-Free Copper Wire 

Ultra-pure, oxygen-free copper (OFC) increases electrical conductivity and promotes a much more stable sound platform, perfect for mellow bass notes and distortion-free high notes and authentic sound accuracy.

Frequency Response

 Harmonic Distortion

  • Harmonic distortion (THD) less than 0.5% across most frequency.
  • Max harmonic distortion less than 1.4% at 5kHz

*Note 1: Lower distortion means the components in a loudspeaker, amplifier or microphone or other equipment produce a more accurate reproduction of an audio recording 

 *Note 2: Distortion below 1% is considered at low distortion Distortion below 0.5% is considered very low distortion

Specifications

  • Driver Unit: 13mm dynamic 
  • Diaphragm: 8um aerospace grade PET 
  • Frequency Response (Hz): 10 – 40,000Hz 
  • Sensitivities (dB/mW): 105 dB/mW 
  • Impedence: 32Ω (1kHz) 
  • Cord material: OFC, Oxygen free copper
  • Cord Type: Y type, round cord 
  • Cord length: 110 cm /43 in
  • Plug: Four-conductor gold-plated L-shaped stereo mini jack 
  • Wearing style: Inner ear 
  • Color options: Shadow Black, Sterling Silver, Shine Orange, Meadow Green and Turkish Blue

Who's TUNAI?

Since 2014, our team at TUNAI Creative has amassed talents from technology leaders in Taiwan and Germany in an effort to put together an organization that is as innovative as it is effective. We have won praise for our efforts throughout Taiwan, South Korea, the United States, and Europe, where our products have been recognized for quality and utility. To date, we have put out two items: FIREFLY, which is a world’s tiniest Bluetooth music receiver that makes it easy for you to upgrade your car and home audio, and CLIP, which is a Bluetooth headphone amplifier that upgrades any wired headset into a wireless headset. In 2017, CLIP won the Taipei International Computer Show Innovative Product Design Award. (Computex d&I Award) TUNAI FIREFLY and CLIP have been noted for the quality of sound that they facilitate, and as a result, we have been asked to develop a set of matching headphones. Having developed and researched extensively in this area, we are ready to move forward on our next project, an in-ear headphone that we are calling DRUM.
