Features of the Sennheiser IE 300 Headphones

1. Price

The Sennheiser IE 300 undoubtedly is one of the costlier headphones in the market. Priced at around Rs.30K or $300 approx, it is costlier than some of the best-selling headphones in the market and is clearly not targeted towards the average public.

The hefty price of the Sennheiser IE 300 makes it clear that the company did not launch these headphones with the intention of competing with its contemporaries. The price point, in fact, put these headphones in a very weird place, where it cannot be compared to other wired headphones meant for a more affordable budget, nor can it be compared to the high level and top-notch headphones that musicians and professionals in the music and entertainment industry use.

The only justification of the price point of these pair of headphones can be that the makers intended it to be a product that bridged the gap that exists between an audiophile-grade sound quality and headphones that are more affordable but compromise on quality. Even though the Sennheiser IE 300 is very expensively priced, the sound quality and overall performance of the headphones are sure to give the users value for their money.

Sennheiser did not come up with different color variants of the IE 300. The only variant available of the Sennheiser IE 300 is in the color black, which undoubtedly, has managed to remain one of the most loved and most popular colour in the gadgets market.

The units themselves, have a very unique design, as they seem to have gold and blue specks on them, which is noticeable only from close proximity. The wire is dark greyish in color, and has been coated with a material very similar to Kevlar, which ensures that the wire is extremely durable and can tolerate a lot of bending without much wear and tear.

The cable terminates at a 3.5mm right-angle TRS jack, which is compatible with most devices and is very easy to use. The headphones themselves do not have an in-built microphone or in-line volume or transport controls, which comes as a big letdown. The earbuds are detachable, and they can be attached to the included cable using the gold-plated Fidelity+ MMCX connectors. These connectors allow the buds to swivel 360 degrees comfortably, and the connectors also allow the user to change the cable that is included with the headphones, with any cable of the user’s choice, provided it is an MMCX compatible cable. 

The box that these headphones come in, comes equipped with three pairs of silicon tips, along with three pairs of memory foam tips. A cleaning tool is also included in the bag to ensure that you can properly clean the earbuds and keep them free from wax buildup. A softshell case is also included in the bag, and this shell case is meant to help you carry your earbuds safely and tangle-free when not using them, and it comes equipped with some cable and accessory organization straps inside it.
