Alpha & Delta AD01 (Black)
- Calculated at Checkout
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.
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.

I first owned a GR07 bass. Although a little bit more bass would be nice, the sound signature was really good. However, the sibilance was too sharp to my liking and causes ear fatigue really fast. And I was too impatient to give it a few hundred hours of burn in time to tame it. Furthermore, I wasn't a fan of the over the ear style due to the cables they used. It was too springy and would go close to slipping over my right ear lobe. So I start looking for another set of iems after only having those for a week. The traditional under-the-ear form of wearing and the sleek looking drivers of this iem caught my attention and the description of the iems made me interested. I was concerned at first about the size of the drivers itself but after contacting lendmeurears about it, I found that its quite acceptable. It does not stick out of the ear that much and is comparable to most high end iems in terms of size. I waited for a few days for reviews of it to come out, just to confirm what I thought about this iem from its description. After reading it, I decided to just go for it and bought it. I bought the upgrade cables along with it as it was on offer and it has less cable memory than the stock wires. My first impression was not as good as I imagine it to be. It was still great, but I thought it would be greater. However, after a few days of burning in and warming my ears up to its sound signature, I was thoroughly impressed and very satisfied. It gives a good, strong bass that's not overpowering, together with great mids and highs. It's almost perfect to what I was searching for. If you would like to know more about its sound signature, there are reviews out there that gives a more in depth analysis of it, so I do suggest you check them out if you want to know more. I used the upgrade cables on mine as I like how it looks and it does give a slight noticeable difference in the bass, in the sense that it's tighter and more cleaner compared to stock cables. To some people however, there may not be an audible difference. But the upgrade cable is still great in the sense that it retains much less of cable memory, which is quite bad on the stock cables. I hate cable memory as it makes the wired iems look untidy when I wear it. Thankfully, the upgrade cables is straight and smooth all the way down to the splitter, where the two thinner cables joined up to form one thicker cable. That thicker wire does retain a little bit of cable memory thus its a bit wavy. But its still alright to me.
Overall, if you're looking for a good under-the-ear kind of iems that has a good strong bass without sacrificing the mids and highs, this is a really good consideration. I thoroughly enjoy my set and look forward to future upgrades it may bring.
