Equipped with a hybrid driver configuration and crafted from quality materials, this model promises rich detail and dynamic acoustic performance.

First Impressions & Design
Right out of the box, the Winter Ultra impressed me with its sleek, dark aesthetic. BQEYZ has always been good at combining visual appeal with comfort, and this model is no exception. It sits comfortably in the ear, making it suitable for long listening sessions.




What really caught my attention, though, was the sound. The dark timbre and the fade-out sensation of the soundstage toward the lower registers reminded me of the previously reviewed BQEYZ Wind. In drum’n bass, there’s a slightly crispy texture layered over bold, weighty bass — it’s less heard and more felt. Remarkably, even when paired with the AP80Pro-X (a DAP known for its leaner low end), switching from low to high gain made the sound more engaging without compromising technicalities. This speaks volumes about the BC drivers’ low-end capabilities.
Sound Performance
Bass
The bass performance of the Winter Ultra is where it truly shines. Thanks to the bone conduction drivers, low frequencies are powerful and tactile. In tracks like The Qemists – Warrior Sound, the thunderous drums feel like they’re rumbling through your bones. Few IEMs manage to deliver this kind of physicality. Despite the AP80Pro-X generally being shy on bass, the Winter Ultra extracts warmth and detail from it with surprising ease — a testament to the hybrid setup’s synergy.
Midrange
The mids are smooth and slightly rounded. Guitar distortion in rock tracks isn’t aggressive or piercing — instead, it comes through in a more mellow, listenable way. This makes long listening sessions less fatiguing. That said, for those chasing a studio-monitor-like neutrality, this won’t replace the likes of the Simgot EW200, which offers more reference-grade mids at a lower price. Winter Ultra isn’t about analytical precision; it’s about musicality and immersion.
Treble
The treble region is laid-back, aligning with the overall fun-focused tuning. There’s no piercing sharpness, making it safe for treble-sensitive listeners. However, the relaxed approach comes at the cost of resolution. You might miss some micro-details in complex tracks — but again, that’s not the goal of this IEM.

User Experience & General Impressions
Winter Ultra is not for the detail-obsessed audiophile — it’s for the music lover who wants to groove, nod, and get lost in the rhythm. The low-end presence and warm tonality create an inviting soundscape. If you’ve enjoyed the BQEYZ Wind, chances are you’ll be equally — if not more — impressed by the Winter Ultra’s engaging and visceral presentation.
What truly surprised me is how even low-quality recordings — like Madonna or Shaka Ponk tracks streamed via Bluetooth from my iPhone 14 Pro Max to the AP80Pro-X — still managed to sound enjoyable. That says a lot. As someone who usually prefers technical accuracy, I found myself drawn into the fun, almost guilty pleasure of the Winter Ultra.

Pros and Cons
Pros
• Deep, tactile, and fun bass
• Non-fatiguing, warm tuning
• Comfortable and ergonomic design
• BC drivers deliver excellent low-end quality
Cons
• Not suitable for those seeking a neutral, reference sound
• Slight lack of resolution in the upper frequencies
• Falls short of highly analytical models in detail retrieval

Conclusion of BQEYZ x Angelears Winter Ultra Review
The BQEYZ x Angelears Winter Ultra is a joy machine — made not for clinical critical listening, but for pure musical enjoyment. Its fun-first tuning makes it incredibly easy to get into the groove, whether you’re into electronic, hip-hop, or rock. If you’re someone who prioritizes emotion and energy over precision and balance, the Winter Ultra will be a blast to listen to.
Even as someone who tends to lean toward neutral tunings and high technical performance, I found myself enjoying this IEM a lot more than I expected. If you’re after strong bass, a musical presentation, and an overall fun time with your music, Winter Ultra is absolutely worth checking out.
