Sora has debuted passive micro speakers that can be attached to the headphone jack. They exist in blue and pink color-Brando provided us with the pink edition that sells for 10$. You can find the speakers at their web site:

Brando ships its products in envelopes via regular mail. Austrian customs seem to leave them alone most of the time(see ther FM transmitter review for a photo of the envelope). The speakers themselves are contained in a small triangular blister:

Here you see a T3 and a TE2 next to the speakers:

The two speakers can supply you with stereo sound. Little bubbles at the bottom indicate which speaker is attached to which channel:

When separated, the speakers can be moved independently. The mechanics that keep the speakers together work well:

Little rotatable clips on the back allow you to attach the speakers to your cloths:

The xyz cm long 3.5′ headphone cable is soldered to the side of each speaker. The connection looks o.k., although I am not sure if it will live very long:

The sound quality is difficult to rate. When powered by an E2, they sound much better and also quite a bit louder than its integrated speaker. However, a T3’s internal speaker sounds much better and also is louder than the speakers on the headphone jack. A T5 is in the middle between the two, but the internal speaker still sounds a tiny bit better actually.

Overall, this is a funky accessoire! The mechanics are fine, and the speakers feel sturdily built. Their sound is better than the sound of a Tungsten E2s speaker-but it is not on par with good headphones, active speakers or the T3. If you own a TE2 or something similar and want to free yourself from your headphones, this is a good solution. But if you look for something loud, active speakers will suit you better!
