Most people assume that using earbuds is just a matter of slipping them in and tapping play on your preferred music app. There's often little care for the fit of the hardware or the quality of the sound. To those people, I would say you are missing out.

No matter what earbuds you use, selecting the right tips can make a big difference. This is especially true when you're working with mid-to-high-end devices, where the right earbud tips can make a huge difference. That's certainly the case with theBeyerdynamic Free Byrd earbuds .

If you're unfamiliar with the concept of "Beyerdynamic sound", you should know that Beyerdynamic is a company dedicated to creating a unique sound for its headphones, speakers, and earbuds. The company focuses on "diffuse field" target response, which refers to a specific frequency response to replicate the sound of flat-measuring speakers in a lively room.

So, why is the feature important? Some speaker and headphone manufacturers go out of their way to artificially boost sound in different ways. Consider Beats headphones, which artificially inflate the bass response to make them sound more dynamic. What then happens, however, is the headphones produce sound that isn't true to the original source.

The goal with headphones and earbuds should be to generate sound that is as close to the original as possible out of the device. Then, if the user so chooses, they can adjust the EQ to fit their tastes. Starting from the "diffuse field" target is a brilliant launching point -- and Beyerdynamic does it better than most.

So, when I received the Free Byrd earbuds, I had high hopes. I'd used Beyerdynamic over-the-ear headphones and knew what to expect from the company. The sound the company delivers is so rich it's almost like gooey caramel for the ears. However, the Free Byrd earbuds really hit home the idea of how important the correct ear tips are to enjoying the best possible sound from a high-end product.

My experience

Even though I'm quite familiar with the importance of earbud tip sizes, when I made my selection and inserted the Free Byrd, I was very disappointed with the sound. I knew, right away, that this was not the "Beyerdynamic sound" I was expecting.

However, I immediately switched out the medium silicon tips for the medium foam tips. With the foam tips, you have to squish them -- I prefer to use the rolling method -- before inserting the earbuds. The foam then expands to create a tighter seal. 

Once I had the right tips, the sound blossomed to become the buttery smoothness Beyerdynamic is famous for. Rush's 'Tom Sawyer' was incredibly vibrant and alive, Barenaked Ladies 'One Week' bounced in ways I'd not heard before, Led Zeppelin's 'Kashmir' was more exciting than I'd ever heard it, Len Cariou singing 'My Friends' fromSweeney Todd was absolutely haunting, and 'Before Yesterday' by Band-Maid was electric.

's buying advice

It's important to understand that the tip selection will make or break these earbuds, as is the case with all headphones with removable cushioning. Not only will it bring the sound to life, but it'll also stop the earbuds from falling out. There are no 'wings' or other bits to keep these earbuds in your ears. So, selecting a pair of tips that create a perfect seal is crucial to your enjoyment of these buds. Keep that concern in mind when deciding on the purchase and when you're finally diving into the music with the Beyerdynamic Free Byrd earbuds.
