These in-ear earphones use the exact same drivers and earpiece as the Sennheiser CX300 series, the only difference between a pair of normal White CX300 and this product is that this has an asymmetric cable, which means that you have a shorter length cable for the left earphone and a much longer cable for the right earphone, which is supposed to go behind your head, along your neck. Hence they are advertised differently as "Sennheiser Eco Ear Canal Headphones"
I have finally received the pink sennheiser cx300 from mymemory as well, which I have compared the sound quality and I can confirm these sound exactly the same.
The earphone plugs into your audio device are the same, the pink CX300s
At under $20AUD delivered (using paypal rates), these earphones are ridiculously cheap for their audio quality.
Do note, that due to christmas stock being shipped around, these will take around 3 weeks (it usually takes 10 days for me, this time it took 3 weeks) to arrive on your doorstep, maybe a little longer.

If you want me to compare them to a product, I will say this:
I believe these $20 pair of sennheiser eco canal in-ears have much better clarity in terms of sound quality as compared to these Beats By Dr. Dre earphones (I've listened to my friend's pair), the Sennheisers have a slightly less smack-in-your-face punchy bass, and rather have a light warm roaring bass in them.
Now an audiophile may say that my comparison is just BS, since anything with Beats by Dr. Dre is just crap and marketting, which I do agree, but I'm comparing a very cheap pair of Sennheisers (less than $20) vs some piece of crap that retails for $229.95, and I am confident enough to say, that these completely blow the Beats By Dr. Dre out of the water.
Comparing to the MetroFi 220vs, I would personally prefer these over them, mainly because these have a warm roar in their bass, clarity-wise, they are very similar (I would prefer these, but that's up to you to decide).

You could have just said 'I have Sony earphones which broke recently and my Sennheiser earphone cable is too short. I appreciate the deal'.
