First off, like to thank Sunny at Heir Audio for providing a review sample of the new 2.AI. As always, dealing with Heir Audio is very professional and a pleasure.
Packaging, Accessories and Build Quality
Like all the Heir Audio universal line, you get excellent packaging. You will get an otterbox-like hard case, earwax cleaner, detachable cable, the earpieces and good quality single and double flanges eartips of various sizes. The 2.Ai comes with a large range of tips, so you will find a great fit no matter what ears you have. These also come with memory wire near the IEM, so locking them into place around your ear is easy.
The cable is mostly tangle free, similar to Westone, it’s double twisted plastic. The 2.Ai comes with a red brushed aluminium face plate, which looks and feels great and really brings the feel of custom IEM’s.
Missing from the accessories, is a shirt clip. As an IEM, this should be standard, as placing this over the ear and down the back, it pulls when moving around. A shirt clip eliminates the pull, so it would have been nice to add that in.
Overall, the build quality is excellent and the added otterbox styled hard case is perfect to have for any musician or if you travel a lot.
As always, I did the usual burn in test and then started listening.
First thing that you will notice is that these bad boys have got a nice bottom end. So many balance armature IEM’s seem to lack the real lows that usually come from dynamic drivers. Listening to Coldplay – Magic, the intro has some real nice low bass notes, which these earphones handled with ease. Having only 2 BA’s this was a pleasant surprise. Treble is not harsh and is very smooth, making long listening perfect. I would say the overall sound is warm, rich and a little laid back. Sound-stage is better than average IEM in terms of both of width and depth, presented in a very spacious way, which is quite impressive regardless of the price.
I also tried these while playing Roland V Drums (TD 30 K) in a live performance environment. Having a full mix of drums and other instruments and vocals, the 2.Ai held its own. Sound-stage was expansive and the instruments came through nice. The cymbals were the stand out, as they were very crisp, cutting through nicely. Kick was also solid. The 2.Ai is really comfortable to wear, playing for a few hours, I almost forgot they were in my ears. Sound Isolation is also excellent. I did miss the shirt clip, but just taped the cable to my neck so I didn’t pull them out of my ears.
Heir Audio 2.Ai is a great IEM. Its comfortable, sound it balanced and expansive, with a rich and warm feel. If you are looking for a great looking earphone, with sound to match and a reasonable price, then this is the one for you.
