Langsdom D3/D3C

2 × ø6mm Dynamic Drivers

$10~$15
4.0/5.0

This one is special and very unlike any other Langsdom product on the market. Why it's so different? Well, let's begin with the fact that the brand is never mentioned anywhere on this product, including the package and the earphones themselves. This model isn't even listed on the brand's official website. It's quite likely that it was intended to be an OEM product, rather than an in-house one. Got these the moment they appeared on AliExpress, and they were very quick to disappear from the store and for a while were only obtainable from the brand's official Tmall store.

Compared to other earphones in the dual-micro-driver sub-category of in-ears, the D3 easily beat earphones like VJJB V1 and VJJB N1 thanks to D3's superior level of clarity, vividness and accuracy. However, compared to champions like the Somic V4, it really depends on your personal taste. While both have a moderate bass response, the V4 is a great all-rounder with a neutral (and natural) sound, while the D3 opt for a brighter and shinier sound, but with relatively recessed mids.

Overall, I truly recommend trying out these earphones if you ever get the chance. These, along with Somic V4, bring the dual-micro-driver category to a new level.

NOTE: For this review, I got the D3C model. While D3 has a single-button inline remote, D3C has a triple-button one.

Pros

  • An exceptional sound quality on the mids and especially the highs. Very suitable for vocal-oriented music styles.
  • Extremely comfortable to wear, with the appropriate ear tips.
  • Although simple, the build quality is excellent and the weight is kept to a minimum.

Cons

  • The bass doesn't go very far into the sub-bass, which makes these not the best for electronic music.
  • Although the mids sound great, they are a bit recessed compared to the treble, which gives the sound signature a V-shaped character.
  • The cable can potentially get stiff in cold temperatures.

Comfort & Fit

Very comfortable earphones. Their shape offers a firm hold and seal even with the included generic tips. I have to mention that while I usually use medium-sized ear tips, I had to use the larger ones with the included cone-shaped tips to get a proper seal.

Lows / Bass

Like many other dual-micro-driver earphones, these aren't shy of mid-bass as well, maybe even exaggerate it sometimes. The sub-bass, however, is a lot to be desired if electronic music is your thing. It's typically shallow and struggling to reproduce deep sub-bass without presenting some minor rattle. With that being said, every earphones model has its strengths, and also weaknesses.

Mids / Vocals

The mids are somewhere between VJJB V1 and Somic V4 in terms of quality - not artificial like on V1, but also not natural like on V4. The lower-mids are a bit recessed, while the upper-mids are emphasized, which is more noticeable in rock and metal music, where vocals appear to be significantly behind the electric guitars. That being said, I quite enjoyed the mids on these quality-wise and find them to be far more impressive than many dynamic-driver-based earphones in my collection.

Highs / Treble

The highs were the most surprising aspect of these earphones. When I looked at the frequency response measurement, I was sure that I'm going to experience veiled and muffled sound. That's totally not the case. Strangly, the treble is shiny and quite detailed. The closest comparison is, again, the Somic V4, and while the V4 maintains a moderate and natural treble, the D3 go for the brighter and sharper treble, which actually sounds quite impressive.
