Perfect for monitoring

The Sennheiser HD-300 Pro over-ear headphones are incontrovertible proof that headphones can offer effective passive external noise isolation – up to 32dB in this case – and still be incredibly comfortable to wear. It's this combination that makes the Sennheiser HD-300 Pro such an excellent device for all kinds of monitoring purposes, although of course they are also a solid choice for many more typical playback functions. What is more, they are made of hard-wearing synthetic materials that will ensure years of outstanding service, while still being so compact that they can be folded up small enough to fit into a pocket.

Optimum audio reproduction

The Sennheiser HD-300 Pro are professional monitoring headphones with a closed-back design and dynamic transducers that produce a sound which could be described as having a warm bass range and rather more restrained trebles. This latter feature is advantageous – and presumably deliberate – considering their primary intended use: Even at higher monitoring volumes, potentially disruptive elements, such as intrusive sibilants, are kept to an absolute minimum. However, audio reproduction optimised for monitoring at high volumes may be less than ideal for making critical decisions when it comes to mixing and mastering. As such, the HD-300s are not high-end all-rounders, but instead dedicated monitoring specialists with impressive external noise attenuation.

Secure, comfortable fit

There is no question that the Sennheiser HD-300 Pro make excellent monitoring headphones for musicians, given the effective passive external noise isolation and optimal playback characteristics. Another relevant aspect with the HD-300s is how well they combine extremely high levels of comfort with a secure fit – great for long recording sessions. The extremely soft, synthetic leather ear and head pads guarantee that they can be worn comfortably for extended periods. Nevertheless, the headphones' fit is never in doubt, even when they are only worn over one ear, as DJs often prefer, for example.

About Sennheiser

In June 1945, Prof. Fritz Sennheiser founded the Wennebostel Laboratory, which initially produced measuring equipment. Commissioned by Siemens in 1945, the young company developed the MD-1 microphone, which was launched in 1946. After the development of further microphones, the company was renamed Sennheiser Electronic in 1958. Two years later, Sennheiser introduced the MD 421 dynamic microphone, which is still in production today and still held in high esteem by many sound engineers. Further groundbreaking developments, such as the HD 414 headphones and the classic MD 441 microphone, hugely enhanced the company's international reputation, eventually making Sennheiser one of the leading manufacturers of microphone and headphone systems in the world.

Ideal in noisy surroundings

The Sennheiser HD-300 Pro headphones are ideal for use in particularly noisy environments thanks to their outstanding external noise attenuation. Equally at home on the sound stage, in the recording room, or in the broadcast booth, the HD-300s ensure that artists can concentrate fully on their own performance as a singer, speaker, DJ, or instrumentalist without being distracted by extraneous noise. Apart from the endless professional applications, however, these Sennheiser headphones are also suitable for simply enjoying music on the go: The comparatively low impedance of 64 ohms means that satisfactory playback levels are easy to achieve even with consumer-grade mobile devices.

great monitoring headphones for studio and in the field, shame about the cable.

LutherD 06.02.2022

I'm a sound artist and field recordist, and I use these headphones both in my studio and in the field.

The sound is what you expect and love from Sennheiser headphones: clear, neutral and full of detail. On top of this, these cans have a lot of isolation, minimising bleed from outside so you can focus on the sound you want to listen to, even at lower volumes (and hence save your ears). Especially in the field this isolation is very welcome. It also makes them good tracking headphones.

The over ear design makes them very comfortable to wear, even for longer periods of time (hours in a row).

My one gripe with these headphones is the cable. They have a little bit of coil to minimise contact noises, and for the rest it's just a normal cable of adequate lenght. However, I found that this design doesn't allow me the flexibility of a fully coiled cable, and when used in the field, the cable (and the small bit of velcro you can use to wrap up the cable) quickly gets in the way of many of your movements. And it doesn't really diminish the contact noises that much. It's for this reason that lately I've left this headphone at home, and choose to use my HD280 instead. It has a very similar sound and practically just as much isolation, but the coiled cable of the HD280 makes it just a lot easier to use (short connection for most of the time, but can stretch to quite a distance when needed). While the cable of the 300-pro is replaceable, unfortunately Sennheiser does not make a fully coiled cable for this headphone.

I spend many hours searching for the right headphones for me.

JODK 05.09.2019

Having been very inexperienced in music production I felt I needed to do a ton of research before deciding what was right for me. I eventually ended up on these headphones having watched several reviews and reading a few articles. I have never looked back, these headphones are absolutely perfect for me, the quality of these headphones is amazing for the price, Sennheiser focus on their "neutral" sound, and I am very impressed with the results. I use these in tandem with my Scarlett 2i2 when at my computer, however I also use them with Spotify when out and about.

These headphones are absolutely amazing and I would recommend anyone who's not an expert in music production, they are my pride and joy and I am so glad I bought them.

Pros:
Very Neutral and clear
Filters out loud noise and prevents headaches
Extremely comfortable
Replaceable cord

Neutrals:
The headphones are able to bend in many ways that make it more compact, however they feel like they may come loose after a while of use.

Cons:
While there are probably some cons, there were none I could think of that would prevent a purchase.

If mixing, use bad headphones too.

Sennheiser sound, but thight fit

HookS 07.01.2020

I bought the Sennheiser HD-300 pro for daily use in my studio. The sound is classic Sennheiser, clear and defined. If you like the sound of the HD-25 you will definitely like these quality headphones.
I like the thight fit of these cans, but I have noticed that it is not to everyones liking. So if you like your headphones to sit loose, these are not for you.
Overall I like the Sennheiser HD-300 pro and would recommend them to everyone looking for a close-backed pair of headphones.
