I’m new to high end audio and I won’t lie, I’m definitely still learning about the segment. One of the things I look for most though are a company that gives me options and quality sound. Beyerdynamic is a company that has been around since the 20’s so they obviously know a little bit about what they’re doing but how do their iDX 120 iE in-ear headphones perform?

The first thing I’d like to point out is everything you get in the box when you receive them. It can be a bit overwhelming when first pulling everything out but don’t let that take away from the performance of the headphones themselves. In the box you get an adapter for VoIP, a splitter for two headphones, two extension cables and 7 silicon tips including 5 pairs of bowl shape tips, one double flange pair and one pair of triple flange along with a soft case to hold it all. Pretty impressive.

Now, you’ll notice that I said two extension cords and that may have you wondering why you’d ever need two and the reason is that the headphones themselves are only about 16 inches so you’ll have to use at least one of the extension cords. One of the extension cables is for Apple and one for non-Apple devices and they’re so indicated by coloring around the 3.5mm connector. At the top of the headphones near the earbuds themselves sit the volume buttons. They’re a little high for my liking and they might be a bit of an issue if you’re out exercising but otherwise, they’ll probably suffice without being ideal.

The cord for the Beyerdynamic iDX 120 iE is a flat cable to prevent tangling and it really does the job. I’ve been using this pair of in-ear headphones for a few weeks now and have yet to come into a situation where they’re tangled coming out of any of my pockets. Since the cable does come apart, you may run into a situation where you’re pulling them out to use them or while in use they come apart but the connection is pretty secure so this should be an infrequent issue if ever. And yes, you can use both extension cords at the same time for an extra long cord.

With so many tips, it’ll be hard not to find the right fit for you. The tips that come default on the iDX 120 iE were just a hair too big (a common problem I have) so I switched out to a slightly smaller pair of the silicon tips and it made a world of difference. Normally with decent headphones you may get one other pair of tips and with some high end headphones you may get two or three but Beyerdynamic really has gone above and beyond for their customers by including 7 tips free to make sure everyone has their perfect fit.

  • Transducer type: dynamic
  • Operating principle: closed
  • Frequency response: 12 – 23,000 Hz
  • Nominal impedance: 47 Ω
  • Nominal SPL: 107 dB (1 mW @ 500 Hz)
  • Sound coupling to the ear: in-ear
  • Cable length and type: 0.30 m / straight
  • Extension cable: 0.90 m
  • Connector: mini stereo jack plug flat cable (3.5 mm)

The Beyerdynamic iDX 120 iE provide a really satisfying, balanced sound. You’re not going to be blown away by the bass here because there doesn’t seem to be an effort to artificially inflate it. This has obviously become more of a trend in recent years with the rise of headphones like Beats by Dre but the Beyerdynamic iDX 120 iE are more of an evenly balanced in-ear headphone focussing more on sound clarity in uppers, mids AND lows rather than blowing out the lows and trying to fix the mids and uppers.

Listening to songs like Take Ü There by Jack Ü (Zeds Dead remix, of course) provides a really powerful kick in the lows while the highs are crystal clear without peaking too highly for that ear piercing effect. Master of Puppets kicks your ass on every beat while making James Hetfield never sound better. Transistor by 311 is an absolute joy to listen to. When your sound is as clear as the iDX 120 iE delivers, you hear absolutely everything in the music and it takes over your senses.

You can pick up the Beyerdynamic iDX 120 iE in-ear headphones for about $110 on Amazon with Prime shipping.
