Sennheiser and Audio Technica have two very similar monitor headphones on the market, but they each carry a few unique features that you should know about. Let’s take a look at both, and see which would be the best fit for you!

The Sennheiser HD 280 Pro monitor headphones have a lightweight design that features swiveling ear cups and are collapsible for easy transportation. These headphones are noise reducing to provide the best quality for your music needs. The ear cups are also made from leatherette material and padded for comfort during extended use.

These headphones come with an amplifier that has four separate EQ modes. This amplifier weighs only 0.7 ounces, making it an easy travel companion for the headphone set. This amplifier indicates the mode you are using via L.E.D. light, and comes with volume control and a hi-fidelity output. This amplifier also has a rechargeable battery that is lithium-ion, guaranteeing long-lasting power and durability.

The Sennheiser HD 280 Pro also comes with battery monitoring technology, so the L.E.D. light reflects your unit’s battery charge with 3 separate colors representing full, low, and charging statuses of the device. These headphones also come with an adjustable headband, which moves easily to help you achieve a comfortable fit.

These monitor headphones provide great variety for your music needs, by working easily with MP3 players, iPods, smartphones, tablets, and even computers. The amplifier allows you to increase the volume while working with these technologies if you so choose to. These headphones come with a closed-back design, for added music enjoyment and comfort. They also feature a 10-inch coiled cable, as well as replacement ear cushions.

These headphones incorporate technology to minimize sound bleed and use 40 mm drivers, as well as copper and aluminum coils, to enhance sound quality. These headphones include a collapsible design for easy portability.

The Audio Technica ATH M40X comes with waterproof ear buds as well, which boost bass for a more powerful sound, and feature clear middle to high notes.
