Wow! Those are so sensitive that you could probably blow on the cable and get sound from them....SimPhonio Dragon D3+ 15th Anniversary Version Earbud is available now
More three-dimensional sound field.
The D3+ 15th driver features a ground-breaking 14.2mm dual diaphragm driver, which is composed of two ultra-thin diaphragm materials, offering both excellent rigidity and excellent toughness.
The driver drive coil has been upgraded to 0.04mm copper-aluminum composite, which is about one-third lighter than the traditional enameled coil.
The magnet adopts custom imported N52NdFeB magnet. With a dynamic impedance of around 32Ω, the D3+ has excellent drive and can be easily driven by a mobile phone or a small USB tail.
Japan Furukawa single crystal copper wire base,8 shares, 640 ultra-fine wire cores.
2 types of adjustable sponge band of different densities are included,It can change different sound styles, and the playability is greatly increased.

Congrats on your new shiny!chaconne arrieved an hour ago and sticks in my ears rn, so couldnt get them on the photo. will write first impressions soon.
I am anxious to hear your impressions on these.
Exactly what @baskingshark said....
iBasso has a "trusted" one as well. The only reason I use the word trusted is because you can actually get these from a lot of Chinese sources, but you are taking a chance that they have wired them correctly, and not just re-labeled a standard adapter (because there are also 3.5mm balanced connections that can use these standard adapters). One has to be very careful when buying this type of adapter.
From an electrical standpoint you can look at it this way: The single ended (here forth known as SE) circuit has only 3 wires. You have the left hot wire, right hot wire, and ground. The ground is the important part here when trying to figure out if you can plug a differing setup into the amplifier/DAP/source. in an amplifier that has any SE connection (typically 3.5mm) the two grounds are tied together.
In a balanced connection you have 4 wires (as opposed to 3 in the SE); left hot wire, right hot wire, ground for left, and ground for right, and they are all separated in the amplifier circuit. An added benefit of having this setup is that you eliminate any crosstalk you might have in a SE connection. So in your amplifier circuit, if you go from balanced connection out to a SE cable or head gear, you are shorting out the ground wires. Since each transducer only has 2 wires, there is no dedicated ground (a positive and negative, and a true ground), and that means that the ground is considered "hot" as well (having electrical potential). So with this setup it would be like taking something like a "household" extension cord that only has 2 wires (not the commercial one that has an extra/true ground) and cutting off the outgoing end (leaving the wall plugin alone), stripping the wires, and touching the red and black together. Though it would be a lesser effect in a sound circuit, it is essentially the same thing that you are doing here.
Since the SE circuit in the amplifier is already set up to have the grounds shorted, it doesn't harm it, but in balanced they are wired internally to be separated and will cause harm to the amplifier if those circuits are shorted.
It is definitely possible that they have provided a properly wired adapter, and if this is the case, you are safe to use it in any 4.4mm socket. Having said that, I am only assuming this, and you might want to contact Temptec to make sure that they didn't do something crazy here. They might have wired the 4.4mm socket to have their grounds shorted like a SE circuit would be, and simply sent you a regular adapter. As much as I paid for my DAP, I would not want to simply "test" this by plugging it in to just any old socket.
You will know because it will stop working. There are some early warning signs sometimes; though I wouldn't count on that just to test things. It could fry it right away, or you could get away with it for a long time. One early warning sign is if one side of your headgear pops, or sound cuts out, or any weird thing like this.
This is one reason that I try to always get head gear that has a balanced connection, because I can come from the source with either SE or balanced just using an adapter, but if you buy head gear with SE, you are limited to a SE connection only from your source (unless you successfully manage to get one of those "special" adapters, and it it wired internally the correct way).
