Dali IO-8 Review

The IO-8 Wireless Noise Cancelling Headphones are a promising option that builds on the legacy of Dali’s previous models while integrating modern advancements to cater to the discerning listener. In this review, we’ll delve into the specifics of what the IO-8 brings to the table, exploring its aesthetics, performance, and overall value.

What You Get

• IO-8 Wireless Noise Cancelling Headphones
• 1.2m USB-C cable (for charging and USB audio)
• 1.2m 3.5 mm mini jack stereo cable
• Travel case

Look & Feel

On the whole, the IO-8’s main design takes after Dali’s older models. The IO-8 tries to freshen up the older build with more premium materials like better textile patterns, better earpads, and an overall lighter frame. Compared to the IO-12, the IO-8 is much smaller, with its ear cups not encompassing as much of your head. This could be a disadvantage for people with bigger ears, as the fit isn’t as snug. These are still very comfortable headphones in my experience, but their ergonomics might not be as universal.

Design & Functionality

The IO-8 uses a 50mm driver made with a custom paper diaphragm and wood fiber materials. This configuration aims for optimal dampening and a relaxed output, and it results in a good signal both with a wire and wirelessly. You won’t get a ton of features with the IO-8 like you do many modern consumer Bluetooth headphones, but it offers enough to enjoy on its own. All of its features are located on the headphones themselves through physical buttons You have an EQ button that simply switches between hi-fi sound and bass boost. There’s ANC on the IO-8 which is extremely strong, almost matching the dead quiet effect that Sony headphones give you.

Bluetooth

Connecting the IO-8 is super quick after putting the headphones in pairing mode. It’s a stable connection that uses aptX HD as its best streaming quality on Android.

Battery Life

With its 35-hour battery life, the IO-8 should sustain a few days of commuting back and forth before needing to charge them fully. There are tons of more inexpensive headphones that have a better battery life, but it should still be sufficient.

Soundstage

Like most hi-fi headphones, the IO-8 relies on the natural stereo field for its soundstage. While Bluetooth tends to constrict the imaging, the IO-8 spreads out with a clear separation between the left and right channels. There’s a sense of dynamic range with this soundstage, as instruments are able to communicate deeper layers than most Bluetooth headphones can. You won’t get an open headspace though, and the positioning of elements feels a little linear and not as distinctive as they could be. The immersiveness of the headphones is still strong though, with the soundstage and imaging encompassing a large portion of your head even if it’s an interior display.

Low End

Without the IO-8’s added bass mode, you still get a thick timbre that delivers a big punch. Activating the extra bass mode adds a lot of extra bloom to the mid-bass that one could consider quite boomy, especially with ANC turned on. I preferred to assess the bass in hi-fi mode where the bass feels more resolving and balanced. Using the IO-8 wired gives you even better bass clarity and detail, with better transients that offer more precision and impact. For listeners primarily using the IO-8 wirelessly though, the bass should still be fun and thumpy.

Mids

I don’t think the mids have the most impressive presentation with the IO-8. Some of the details are muddled in a pool of overwhelming resonance and it never feels like the sound signature highlights any significant texture from instruments. It lacks weight, with notes feeling like they’re being glazed over. The upper mids show a bit more presence and control, making vocals and some instruments more clear.

Highs

The highs are very reserved but more organized than most of the sound signature. While I don’t think there’s a significant sizzle to the timbre, you get a clear tick that helps pronounce the treble better than other areas. It helps accentuate high-frequency content even when the region starts to smooth out and drop off.

Summary

The IO-8 Wireless Noise Cancelling Headphones present an alluring option for audio enthusiasts looking to elevate their listening experience. With a unique combination of premium materials, and substantial noise cancellation, these headphones stand out in a competitive market. While the design may not accommodate all ear sizes perfectly, and the mid-range performance leaves room for improvement, the headphones still deliver a rich audio experience that will satisfy many users. If you’re seeking reliable headphones that marry quality sound with stylish aesthetics, the IO-8 might just be the perfect fit for you.
