 NOTE: This listing allows you to purchase the AD01 set with the upgrade cable only. This means means that the original black cable will not be part of this set. The upgrade cable will improve the clarity and the tightness of the bass in comparison to the black cable. 


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

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.

    AD01 with upgrade cable

    Its still amazing, great V shaped sound with a bang for a buck auction. Thats my second I got in the past years, I bought the first in 2015. The only issue was that one it had a contact issue between the cable and the driver. Thats why I ned a second one and it was on a really great price.

    Hardy and Good Sound

    Not really an audiophile but i am a big fan of the design concept with the plug in wires. As most of my previous IEMs suffered from wire damages, this is a welcome concept.

    Sound isolation was decent. Very comfortable for long usage as well. I listen to rock and metal and some blues. I think it does well for these genres with bright and warm soundstage.

    Not very boomy like people make them out to be, but provide a fun sound signature, are very comfortable, isolate really, really well and they do have some bass.
    But not a bass head headphone.
