Alpha & Delta AD01 is the result of a collaboration between Lend Me UR ears and a Chinese manufacturer. In English, the noun "alpha" is used as a synonym for "beginning", or "first" while the greek symbol for Delta is used to denote change. Thus, the name Alpha & Delta was coined to represent a new chapter in LMUE's history and the wish that this brand will chart a new direction for the company. 

Dual Driver Design for Excellent Sound Quality

In designing this IEM, we aimed to create a pair of earphones that has a strong punch bass while maintaining the overall clarity in the mids and the highs. To this end, a dual driver design is used for such purposes. 

Modular Design

AD01 also adopts a modular design. This means that that drivers and the wires can be easily replaceable if damaged or lost. The drivers and wires will be made available for sale separately.

Well designed connection pins    

For AD01 to use a modular design, the wires needs to be detachable. However, several existing solutions for the connector pins can lead to loose connection overtime. To this end, AD01 overcomes such build quality issues by adopting the 2mm dc plug connector pins which are extensively tested for reliability.
