Etymotic Research HF5 Reviews

Detailed sound and imaging. These isolate noise very well.

Crutchfield Customer Review (What's this?)

I was reluctant on buying these seeing as there were no reviews and being unfamiliar with Etymotic. Well, don't let that deter you from purchasing these. These bring out a lot of detail and are great with imaging compared to the Klipsch earbuds I have been using. The Klipsch have more bass, but they lack the detail, imaging, and noise isolating that these have. Happy with these. Definitely a brand I'll keep on my list from now on.

Pros: Like I said, more details in the music. These are very comfortable earbuds for walking outside. Noise isolation is little too good. Gotta be careful wearing these outside, as you can barely hear anything around you.

Cons: These are not good for taking in and out of your ears every few minutes. Once set in your ears you want to keep them in there. They go deep in the ear canal.

Product Research


Overview: The Etymotic Research hf5 in-ear headphones offer excellent sound quality and noise isolation. The headphones come with a variety of ear tips for superb noise isolation, a clothing clip, wax filters, and a zippered storage pouch.

Balanced-Armature Drivers: The hf5 earphones use high-performance, precision matched ACCU-Driver balanced-armature drivers to achieve a high 105 dB SPL sensitivity, and an 85% response accuracy from 20 Hz to 15 kHz.

Noise Isolation: The hf5s have a closed-back design and noise-isolating ear tips to achieve a 98% reduction (35dB to 42dB) in ambient noise. The 3-flange silicone ear tips work with most sizes of ear canals to ensure a comfortable fit and a proper seal. The foam ear tips are heat-sensitive and will expand inside your ear canals to perfectly form to the contours of your ear to block out ambient noise. The earphones also come with an option for custom-fit earpieces.

Cable: The hf5 earphones have an attached 48" cable with an angled 3.5mm plug. There is no in-line remote or microphone on this model. (The Etymotic hf3 is identical to the hf5, but adds a microphone and 3-button remote for controlling music and phone calls.)

ACCU-Filter: The Etymotic earphones are equipped with special ACCU-Filter wax filter to smooth the frequency response and prevent earwax from entering the earphones. The filters are placed at the end of the ear bud nozzle, and should be changed when they become clogged with ear wax. A filter removal tool is included in the package.
