Have questions about your Direct Sound headphones?
Let’s see if we can help.

 

People are talking about us – and they’re also asking us a lot of questions. Here are some of the questions we get most often. Of course, if there’s something not covered here, feel free to contact us.

 

What is the difference between the EX-29 and EX-25?

The EX-29 has a Noise Reduction Rating of 29 dB and weighs 11.5 ounces. The EX-25 is more compact, has an NRR of 25 dB and weighs 2 ounces less. While both models feature TruSound™ Tonal Accuracy, the EX-29s use ultra-fidelity speakers with a sensitivity of 114 dB at 1,000 Hz. EX-25s feature a sensitivity of 107 dB at 1,000 Hz.

What Is NRR?

NRR or Noise Reduction Rating is a standard rating for how much a given product reduces external sound. The problem when specifying noise reduction amounts is that it varies with frequency – treble is generally reduced much more than bass. For example, the EX-29 attenuates 36.7 dB at 8,000 Hz and 25.2 dB at 500 Hz. NRR is used to give a standard single number as a convenient way to compare apples to apples.

Other manufacturers often specify their noise reduction figures by using only a single high frequency to make their product look better. We could just as easily claim our EX-29s attenuate by 36.7 dB and we wouldn’t be telling a fib, but we don’t believe in misleading our customers. Rest assured the EX-29 and EX-25 offer the industry’s best isolation across all frequencies.

Do Direct Sound headphones require batteries?

No. All of our headphones use environmentally responsible passive isolation to naturally isolate unwanted sound.

Do the headphones need to be tight to block sound?

No. The design of Extreme Isolation headphones lends itself to natural isolation. Want to hear it for yourself? Visit a local dealer and hold the headphones in your hands while music is playing loudly. Gently touch the cup together – and you won’t hear a thing.

Do the headphones block out all sound?

No. The headphones are designed so that you can still “feel” the sound pressure of your instrument.

Does the headband stretch?

Yes. The newly designed IncrediFlex™ headband is incredibly flexible, durable and can be stretched to fit your exact requirement.

How can you tell the right ear from the left?

The right channel speaker cover is solid red so that you can easily identify the right channel in dim light or when in a hurry. No need to frustrate yourself looking for a tiny R or L.

Remember – Red is Right.

How do I use the adapter?

The EX-29, EX-25 and ONE42 headphones include a screw-on ¼" (6.3 mm) adaptor. This can loosen with regular use and cause static, so please be sure it is screwed on tightly.

Are the headphones difficult to repair?

No. The headphones are amazingly simple to repair in seconds with no tools or soldering required. Replacement parts are always available. If you are still not comfortable repairing the headphones, simply return the product to us. All you have to do is pay for the parts and we’ll fix them for free.

Are they safe to use anywhere?

No. These provide such a high degree of sound isolation, you should never wear them when you need to be fully aware of your surroundings, particularly when driving, biking or using any type of machinery.

What is the warranty?

We offer a one-year warranty for EX-29, EX-25, HP-25 and ONE42 models. The e.a.r.Pods and Serenity II have a three-year warranty. We will repair or replace any item found to have a manufacturing defect. Just return the product to us with proof of purchase, or take it back to the store you bought it.

Do you ship worldwide?

Yes. We usually ship via United States Postal Service (USPS). If you have another shipping preference, just let us know.
