Have you just spent all morning getting ready for work and getting every single detail of your hair looking just perfect? Do you want to fire up some tunes on the commute in to work, but don’t want your time preening to go to waste by throwing a pair of over the ear headphones on? Sennheiser has a couple of options for in-ear headphones that sound, feel and perform just as great as a traditional set of headphones.
Introducing the IE 600 and IE 900 headphones. We’ll start off with chatting about the IE 600’s and then make our way up the mountain to the IE 900’s.
The IE600 Wired In-Ear Monitor Headphones are comprised of an Ultra-Resilient ZR01 amorphous metal housing and utilize two 7mm TrueResponse transducers. These transducers are assembled by Sennheiser and they are built for the long haul. The production of the amorphous metal housing is completed by both machine and manual steps in a plant in Germany. The result of the careful manufacturing is a pair of IE 600 headphones that will remain in near perfect condition year after year of use. The IE 600 headphones have a robust protection against corrosion and scuffs and dings from wear. These headphones are designed to keep delivering amazing sonic – and visual – joy for many, many years.
We’ve tried these out and not only do they sound incredible, but their comfort is off the charts. Included with the IE 600’s are two different styles of ear bud tips, both silicone and memory foam, and they are provided in three different styles to make a comfortable seal in the ear. The ear hooks themselves are flexible and have some adjustments to ensure long-lasting comfort. The IE600 is quite possibly the best audiophile in-ear headphones we’ve seen, and we have seen A LOT.
Included in the box with the IE 600’s are both a balanced and unbalanced para-aramid reinforced cable with a 4.4mm and 3.5mm connector, respectively. There is also a balanced para-aramid reinforced cable with a 4.4mm connector. Another nice touch by Sennheiser is a serial numbered carrying case and a presentation box with a signed customer certificate as well as user manuals.
Next, let’s look at the IE 900’s. The IE 900’s physical characteristics are that unlike the IE 600’s these are made of a precision-milled and anodized aluminum housing. A five-axis CNC machine precision cuts each housing individually out of a solid block of aluminum. Once the aluminum is anodized the housing of the IE900’s are super resistant to showing signs of wear and corrosion. On top of that, the drivers in every pair of IE 900’s sold are matched during the manufacturing process to eliminate variance, which provides a totally accurate soundstage.
A huge point of separation between the IE 600’s and the IE 900’s is that the IE 900’s utilize what is referred to as and Acoustic Back Volume. What is that, you’re asking? It’s a small chamber within a chamber that Sennheiser has tuned to separate the low frequency and the mid-range frequency. The back volume helps to achieve a clear and natural sound signature by controlling the direction of the overall volume as it flows through the transducer system. The result of this is a very consistent and disciplined bass and mid-range listening experience.
Comfortable? Comfortable. Included with the IE 900 headphones are silicone ear adapters as well as three different elastic ear adapter sets in three different sizes. The “what’s in the box” for the IE 900’s is almost exactly the same as the IE 600’s except for one BIG difference. There is a balanced 4.4mm (quarter-inch) cable included for a connection to a hi-fi system in the home. Why have the best headphones in your ears and not be able to utilize them in your home system? Yeah, Sennheiser thought of that too.
Pros: Carefully designed headphones priced for all audiences.
Cons: Wired headphones are looked down on in favor of Bluetooth.
