At first, Qian 39 does not sound as good as Qian 25. After playing a few songs,  I found out that Qian 39 style is warm sound. Its features is the warm human voice , delicate and melodious. Like waking up in the lazy afternoon. Soft and beautiful.
Midrange is superb.  Treble is o.k. Bass is loose and flexible but depth in the low frequencies not so much when compared to Qian 25.

I have the  qian 39 High Quality Headphones Earbud  which is a more treble orientated bud in the same price range. For the price, I found it to represent excellent value for money, possessing a high level of detail retrieval  and a good soundstage. On the other hand they lacked bass; but this was acknowledged in the seller's product description - so that was fine.

I've been giving these buds a good long listen and I concur with most of this review. One very big advantage of the qian39 is that it is a bit smaller and for me it's a perfect fit. Not to mention that I can lie on my side wearing these without causing any discomfort.
 
The qian39 is giving my zen2 a huge run for the money...the zen is a bit more detailed and has a slight edge in soundstage. This really makes me wonder how good the zen would sound if it could actually fit perfectly in my ears. Sigh...
 
But my hats off to the qian39, excellent detail and performance on the full frequency range for an embarrassingly low price.

So i got my qian 39 in the mail today........ I dont think i have ever been so impressed by an earbud.  I have the ve monks, tp musics, au glamour, ty 650 and rose masya.  And these little qian 39s are just really impressive.  I wont say they beat the ty 650s or beat the rose masyas but lets just say they give them a real run for their money.  They are like a ty650 with bass boost and I would say ever so slightly warmer sound signature with a wider sound stage.  Compared to the masya the masya wins in airiness but in all honesty the masya sounds more digital while the qian 39 more organic. 

Now the qian 39 earbuds are bass buds the most bass i have heard from an earbud thus far but they are no slouch in the other frequencies. But i would not recommend them to anyone looking for  flat response.  These are like a bass heads wet dream in earbud form.  I would not boost the bass on these they have plenty more than other buds boosted.

So what about detail retrieval? I would say they are very close to the same level as the ty650 but behind the masya in detail retrieval.    
 
If you dont have these i would highly recommend you pick up a pair they are supper cheap and they are just very good.  I would never recommend the ve monks over these ever.  If i were to give these a price in comparison to the rose masya and ty 650 i would give them a value of around $80 dollars.  Why because they perform so closely to the ty650 but have more bass.

PM price Qianyun Qian 39 + Vido (Window) Ear Buds + postage to kuching if still available
