Wireless Hunt: Sennheiser HD1 Free

(Update: This is being posted post-humorously; I've already returned the HD1 Free IEMs as they were god awful. How do these things sell at 270 dollars!? I didn't even bother to take photos of these as they went back to quickly!)


The Pixel 3 is USB-C only. Goodbye headphone jack! Not exactly cool, my dudes, but it’s a sign of the times, I guess. I don’t really feel much like prematurely wearing out the USB-C port, and a good USB-C DAC on a dongle is something like 45 CAD normally, so I’m going to try retiring my Etymotics in favor of a Bluetooth option. I honestly don’t feel I’ll be able to tell the difference between LDAC or AptX and a wired connection at this point, so I may as well jump on a few. Can we find something as perfect as Etymotic’s offerings? Let’s find out.

First up! The Momentum HD1 Free. Fairly light weight Bluetooth neckbuds, mostly plastic construction. The cable is long and awkward, and the 6 hour battery life is mostly uninspiring for a 170 dollar (on sale!) pair of Bluetooth IEMs.

Initial impressions: I couldn’t get a fit with the stock tips. Even the large size didn’t fit my right canal properly. This is kind of expected as I’ve got big and weirdly shaped canals, so I normally gravitate toward a deeper fitting IEM. I threw on a pair of “medium” gel filled silicone Monster Super Tips and the fit was extremely good. The Super Tips in medium were a fair bit larger than the large from Sennheiser… Weird. Once fitted they were barely noticeable thanks to the weight of about 40 grams.
Sound quality wise… These are most likely getting returned. I’m streaming AptX from my Pixel 3 with high quality Google Play music source, and they’re muddy, sloppy, and veiled. They lack the clarity, speed, articulation, and intimacy of the Etymotics I’m used to, favoring a more inflated low end and recessed mids and highs. There’s also some weird sibilance on certain consonants, depending on the artist that’s likely to get fatiguing. Sound improves slightly with EQ, but it still kind of sounds like you’re smothering the music with a pillow. There are tracks they do well with, for instance Kygo’s “Here for You” comes across fantastically, and Ella’s voice is well articulated and smooth, but something like Fall Out Boy’s “The Phoenix” is an absolute mess with the midrange details a complete jumble – You can’t pick anything out.

There were very few cutouts with the Bluetooth connection, being 4.2. I expect a few as I believe the antenna is on the opposite side of where I keep my phone, and I got some barely noticeable drops, but overall solid connectivity.

In conclusion, these are great for some genres like electronic and hip hop, but not great for others like rock. I’ll likely give them a few more days but will be sending them back. I have a few more goodies on the way, so the hunt continues… Up next is the Sony WI-1000X which seem really promising with a dual driver setup (Single dynamic and single balanced armature, which I’m hoping will offer a more neutral, detailed sound), and a bunch of cool tech like ANC and a better battery life. I also snap-bought the Sennheiser Momentum True Wireless, which look like the first good pair of true wireless buds to me. Initial reviews seem to be positive, slightly v-shaped but not lacking in clarity. We’ll see what they’re like when they get here.
