riseuplightSendy Aiva. Great headphone, comes with 4.4mm cable. Honestly, though, I think most of the time you should just buy the cable that is built for your amp. These adaptors are made to break with their poor design.
micahjrose"These adaptors are made to break with their poor design."
That's a bad blanket statement. These ones in particular are very well built. They are almost solid metal and are made to last.
That being said yes generally you'd want to use whatever fits naturally but sometimes that isn't possible. Either the headphones don't allow you to change to cable, cables are too expensive, or it's just more convenient to get something with a right angle vs going in straight. Whatever the case may be there certainly is a market for these things and these are one of the better ones.
legaceezThe circumstance you are describing is rare: you already have a 4.4mm cable and you don't have a 4.4mm source. If you have a 4.4mm cable, this can be reterminated for a fraction of the cost of a new cable.
The other adapters from ddHifi are great. This one is made to break because of the problem of leverage and frailty of 2.5mm connectors. The collar exacerbates the frailty. A robust 2.5mm (no collar) male jack with a short length of wire connected to a 4.4mm female connector is a far better design. Four inches of copper are unlikely to change the sound.
Just because there is a market for a bad product doesn't make it good. People like all kinds of stupid things.
micahjroseThat's an inherit problem with 2.5mm connectors so it would be unfair to fault DD for that. Also note the drop was originally for both a 2.5mm and a 3.5mm adapter and if your amp/device only accepts a 2.5mm well then what choice do you have?
Just because you don't have or see a specific need for something doesn't make it a bad product. No matter how niche something is, it's valid if there is a use for it.
legaceezI'm not saying people can't want this, but retermination of a cable won't cost much more and is a better solution than this 4.4mm to 2.5mm adapter, albeit potentially slower (though Drop is not known for speedy delivery).
As I've said before 2.5mm is frail, so having the plug body not press directly against the source is bad design. The collar prevents the adapter from having the broadest possible base. I'll say one more time: the need for 4.4mm to 2.5mm is rare, and if you have this need, this is not the best solution. Best solution is reterminate your cable, 2nd best is an adapter that is not of the direct connect variety (that is, wire between male and female connectors). If ddHifi wants to make a 4.4mm to 2.5mm adapter, they should ditch the collar on the 2.5mm plug and give a broader base. I also have it on good authority from a cable manufacturer that right angle connections break more, because they rotate and leverage breaks the connector.
