I tested ddHiFi's new entry-level IEMs, and they're ridiculously good

(Image credit: Apoorva Bhardwaj / Android Central) The budget IEM category has countless choices, and it's the entry-level where things are particularly interesting. ddHiFi is a well-known Chinese outfit, and its latest collaboration with India's Headphone Zone has resulted in the Skyfall and Iris, two IEMs that target the same category.The Iris has a 10mm dynamic driver and costs ₹2,699 ($28), and the Skyfall has the same 10mm driver alongside a BA driver, and it comes in at ₹3,699 ($38). Both usually cost ₹300 ($3) more, but with Headphone Zone having a sale, now is the best time to get your hands on either if you're interested.

I'll get to the sound in a little but, but before that, I want to highlight the design. The Iris has a green hue that looks great, and the Skyfall has a bold blue design that makes it stand out.Both IEMs have a 3D-printed shell, and the design is definitely a plus point; you don't usually see this kind of build quality in in the entry-level. I like the see-through design as it does a great job highlighting the drivers and the connectors housed within the shell. This is even more evident on the Skyfall, as you can easily make out the dedicated BA driver.(Image credit: Apoorva Bhardwaj / Android Central)Either shell is on the larger side, but I didn't see any issues when it comes to usability. The sound nozzle on the Iris is a smidgen bigger than that of the Skyfall, but this didn't prove to be a problem.You get a decent selection of ear tips with the IEMs, and the Iris has a 3.5mm cable, with the Skyfall bundling a 4.4mm balanced cable. The default cable is good enough, and the braided cable has a nylon sheath that gives it a little better durability.(Image credit: Apoorva Bhardwaj / Android Central)Both IEMs sound great in their own right. They have detailed bass, a clean mid-range that allows vocals to shine, and good treble extension without coming across as bright. I like the Skyfall a little better in this area; the addition of a BA driver leads to better detail in the mid-range and a livelier overall sound, and in my testing, I preferred it to the Iris. You also get better much sub-bass energy, lending itself very well to mainstream music.Get the latest news from Android Central, your trusted companion in the world of AndroidThat isn't to say that the Iris is bad by any measure — it has standout vocal presentation, and if that's what you need, the Iris will be better-suited to your needs.

It costs a little bit more, but you're getting a more engaging sound, and a balanced cable. I also like the blue hue a little better, and I think it's a good all-rounder at just ₹3,699.
