BQEYZ Spring 2 Review

Specifications 

 

Piezo-electric + Dynamic + Balanced

Sure hybrid IEMs are fairly common now. You blend a Balanced unit with a dynamic one and manage to get the best of both worlds. But, BQEYZ decided to take it to the higher ground with the Spring 2.

In addition to the 13mm Dynamic and Balanced driver, BQEYZ decided to add a Pieze-electric one. Made of 9 layers of ceramics cylinders, this driver is supposed to deliver exquisite, high to ultra-high frequencies.

So here you have :

  • High frequencies: the 9-layers piezoelectric
  • Medium frequencies: a classic balanced armature driver
  • Low frequencies: one 13mm Bionic diaphragm dynamic unit

Obviously, with three different technologies fitted in one IEM, the crossover can be a nightmare and lead to catastrophic results. So BQEYZ mixed physical frequency division with a “coaxial dual-cavity patent dynamic ceramic horn”.

Pretty clever on paper, so I’m curious to hear how that will translate, in real-life performances.

Sensitivity / Hiss 

Impedance is low, sensitivity is high – whatever the settings – so yes, you can drive those IEM’s with nearly anything, but it will shine only when hooked on a good DAC or DAP

Obviously, take a balanced version, as far as possible.

Sound performance

My main sources were: iBasso DX160 / NuPrime Hi-mDAC / FiiO M3 Pro. Trusted sources from trusted brands that I used extensively for the past weeks.

As usual, files were played from either Qobuz / Spotify or my own music library. Some tracks will be highlighted, just so you can try them home too!

Overall signature

As always, what’s really matters at the end of the day remains the sound factor. 

And what the BQEYZ Spring 2 lacks in design, it gains in performances. The dual-driver – Piezo+dynamic – makes super crisp details, at all volume, even with non-audiophile sources. Obviously, the highs take the lead but it’s not too sparkly, or even hissy.

Imaging is good but compared to its direct competitor, the soundstage appears a bit too narrow for my taste. That said, mids and highs are not forgotten and the Spring 2 gives a surprisingly nice experience in that regard. Voices are rock solid, almost too clean but that’s the charm. 

Resolution and clarity are sublime and whatever I throw, the BQEYZ remained rock solid. There is no sibilant, no peak, or no obvious caveat. In fact, I expected those ears to display a V-shaped signature, but that’s clearly not the case. Lows are deep, with good texture and contrast. Still, compared to the FH3 or even the DT200, it’s slightly too shy, for me.

Powerful mids, good impact, natural voices, deep bass, and excellent clarity. The Spring 2 is pretty good overall, and the more I listened to it, the more I was surprised to discern details, I didn’t expect to hear on those ears. First regret / 3 years later from Steven Wilson was my special song on the BQEYZ, a multi-segment track that could have been real torture, but ended to be a pretty fun trip.

It misses explosives bass, but paired with the DX160, I could play with the EQ and push them a little more. Most people will find the lower end level perfect as it, but I’m always on for more bass and rumble, especially when I’m walking. It’s an extra kick.

To sum up, the BQEYZ Spring 2 sounds good, very good even. It’s smooth, clean and trades soundstage width, for details.

A nerdy guy with a passion for audio and gadgets, he likes to combine his DAC and his swiss knife. Even after more than 10 years of experience, Nanotechnos still collects all gear he gets, even his first MPMAN MP3 player. He likes spreadsheets, technical specs and all this amazing(ly boring) numbers. But most of all, he loves music: electro, classical, dubstep, Debussy : the daily playlist.
