Listening to my brand new BL-05s now. Some impressions.
At first, I was underwhelmed by them. A few days ago. They didn't sound much different than the BL-01, whose tuning seemed more restrained and 'audiophile' than the previous BL-03.
I had issues with the BL-05s (the green ones, that's what I'm discussing here):
-I thought that the soundstage was circular and pedestrian
-I thought that some instruments were just too loud relative to others
-I thought that the 'magic' of the BL-03's exaggerated bass and weird treble was gone
I was testing them on rock-and-roll, and especially metal, which they were supposed to be good at. It seemed to me that the BL-05s didn't have sufficient bass for metal, not sounding as engrossing as it could be.
Well, they might benefit from some 'warming up.' First day, I had taken it from the -5 C metal mailbox and listened to it. But they've had some time to settle since then.
I've been comparing the BL-05s in my mind to my new Starsea, NA2, and NM2+, which are expected to outpace the BL-05s in technicalities. But after a few days, the BL-05s is giving me some decent performance in some unexpected tracks.
Here’s what I found them performing unexpectedly well:
-atmospheric synth, like the original recording of “Love on a real train” and its various remixes
-orchestral remixes, including those by high-school bands!
-high-end video game OST and remixes
It was mediocre or subdued with:
-actual orchestral, individual or small string performances, real OSTs
-It was kind of harsh, grainy, or even steely [let’s say lo-res except for soundstage] with pop.
-seemed a little ‘colourless’ with metal, as well. Whatever sound attributes are getting ‘rounded’ or confined with the BL-05 seems to be unhelpful in these genres. BL-05s has the speed and harmonics, and the electric guitar, and most of the soundstage but maybe not the bass for metal. Compared with V90. Guess it depends if you’re a basshead.
It sounds subdued with AC/DC “Big Guns,” Slayer “South of Heaven,” Alice in Chains “Them Bones.”
The overall character of the BL-05s seems to be that it is fairly coherent and musical, but rounding off treble and bass to 'safer' levels as compared with dedicated performers in those categories. This has positive and negative effects, depending on genre. I'll briefly discuss some
characteristics.
Characteristics
-BL-05s is capable of rendering brass, saxophone, and woodwinds in a fairly natural way in its price category. Especially saxophone.
-Vocals are also quite natural, or at least pleasant. Especially orchestral/harmonic choruses. However, less-prominent vocals are sometimes lost in the background against percussion or even bass tracks. [Not usually, though, and not by much.] Key vocals are usually prominent enough.
-In small orchestral arrangements, guitars have decent timbre, and are sometimes foregrounded more successfully than with other IEMs.*
-The BL-05s soundstage is actually decent. Nothing spectacular or holographic for the most part. However…it can group bass and percussion sounds provocatively at the L-R poles while simultaneously placing bells and similar bright-sounding instruments ‘higher’ in the soundstage. I would say it is superior here to the BL-03 and BL-01.
It also produces an ‘ethereal’ quality with many synth and some string-heavy recordings.
-The dynamics seem average and nothing special at first. However, it’s in a tough fight with the T4 in the “Chilled Euphoria" rendition of “Love on a Real Train.” BL-05s evinces creeping dynamics that you slowly notice as sound builds on top of you.
-In detailed tracks, the BL-05s seems to round off extreme treble and bass somewhat, preventing them from being as harsh or peaky as they could be. It isn’t as bright or resolving with strings and other things as the TRI Starsea, but it’s always less fatiguing with high-quality recordings than Starsea or T4. For classical recordings and OST, some will find the BL-05s too rounded-off and constrained in its overall sound profile.
-To elaborate on the previous point, Starsea was more compelling with "Star Trek II: The Wrath of Khan (Newly Expanded Edition)."
-The BL-05s just sounded unambitious. Sure, it was coherent. But it was kind of the 'let's sit in the warm bathtub' version. By contrast, the TRN Starsea went crazy in all the ways you would expect. BL-05s version was like a gentle Southern ball. Also the percussion was a bit overdrive in 'Surprise Attack,' but not as bad as it could have been:
Star Trek II: The Wrath of Khan
There are points in 'Surprise Attack' where the strings are really supposed to jump out, as they relate to film cues. But they just sort of get submerged in the general piece. It doesn't grab you. The bells are mostly right, though. [The bass string sections is reminiscent of the Star Trek 6 album, for those who are familiar.] What a contrast to the Starsea. Starsea presents percussion forward and fierce, just shy of piercing. Stronger imaging/separation. Brass a little too bright. Definitely more analytical. The strings, though. The strings are where the Starsea kills the BL-05s in this and nearby tracks. Those individual plucks are more foregrounded and apparent. And they're stirring. Like they're supposed to be.
BL-05s is soft, sweet, almost syrupy here when compared here with the Starsea.
The Starsea's strings are sweet-and-sour, it can more convincingly render different emotions from the same string section simultaneously. So I definitely pick the Starsea over BL-05s in this album.
-T4 and Starsea are far more analytical than the BL-05s, but the BL-05s still has good separation and can hold its own in imaging at times.
-Strangely, the BL-05s sounded comparable to my memory of how the TRN BA5 rendered YSSY’s Mandalorian theme remix:
YSSY's Mandalorian synth remix
The BA5 produces a cleaner sound. The BL-05s is muddier here, but not by much. Not BL-03 level. The BA5 and BL-05s hit about the same here. BA5 scatters the instruments a little more across the soundstage, BL-05s might be tighter and more coherent. With more restrained percussion. BA5 has slightly better dynamics here. BL-05s overall more restrained and analog with this track, which can be good or bad. [BA5 more 'digital' and 'expansive.'] In fact, BL-05s warmer, BA5 more 'haunting.'
Let’s do another comparison. There's an incredible rendition of
'Love on a real train' by some students:
'Love on a real train' live orchestral
Here, the Starsea shines as you would expect: exact separation, excellent imaging of individual instruments, very analytical. Fairly natural trumpet, some of the higher-pitched instruments a bit bright and piercing. Not as coherent as some might prefer.
With the TinHifi T4, you have kind of piercing [very resolving] Clarinets, sweet flutes, subdued trumpet, and natural strings and vocals. [low-textured bass as is frequent with T4]. Xylophone not as piercing as it could be. If you close your eyes, it's almost as if you're in the room with them, but it's still discerably a recording.*
Now, the BL-05s. Well, I was pleasantly surprised and sat up and took notice.
Again, like our friend the T2+, it's very coherent. But it was presenting the instruments individually very successfully. I don't know if you can close your eyes and feel as if you're there, but maybe at the centre back-row, flanked by clarinets. With vocalists at the back of stage. Bass string not so textured, but more than T4. Shaker, xylophone, crystal clear and discernible. Impressively, the guitar is distinct and apparent, which is not the case with many playback devices. Like the T4, I guess the trumpet was a bit muted.
Another comparison:
an obscure Serbian video game called Underrail:
Underrail
I tried this military anthem with the T4, which presented everything up-front. It separated the instruments fairly well, and put them right in your face. It lacked coherence as sometimes occurs with the T4. Not with the BL-05s. The marching sounds background the entire piece, sometimes in the foreground, synths always in the foreground. Vocals should maybe be more prominent? I'm not sure.
There's another track, Scientific, where the T4 shines a bit more. Very thick sound, sharp rendition. But the BL-05s is better. I've heard this track alot, and the BL-05s gets the ambiance right. Just the right amount of mellow. Similar to my bookshelf speakers. We see a pattern here, where the BL-05s is subdued and coherent, good harmonic shifting and it doesn't lose melody, much less fatiguing.
Some of my initial impressions remain, though. Where the BL-05s kind of falls apart for me is with pop music, from the Grand Theft Auto: Vice City soundtrack [in-game, with 3D audio headphone settings]. I also tried the BL-05s a few times with Michael Jackson's "Smooth Criminal" from the music video on Youtube:
Michael Jackson - 'Smooth Criminal'
The initial flowery music is harsher than it should be, and the soundstage is confined. The treble strings and bell(?) were okay. Sounds that should be subtle [whispers, guns being cocked] were shouty. The main melody track is piercing, and drowns out Jackson's voice [which, at least, is clear.] Jackson's high-notes are piercing. Personally, I think the BL-05's performance with this recording is something of a disaster.
I also tried the official music video for “Billie Jean.” This one wasn’t quite as harsh. Still more resolving of the percussion shaker and have more ‘gray noise’ than I’d like, but it was passable. Like something I might expect from an earlier KZ. Except the soundstage, which along with the imaging was overall fairly impressive, as with for ‘Beat it.’ I dunno, maybe I need to go to high-quality recordings. The CD-quality audio on the iPod touch also didn’t impress me, here.
Just seems harsher or grainier than I would prefer. Steely, even.
Conclusion:
Overall, the BL-05s reminds me of the AM radios it is coloured after. Something that takes up a big chunk of the room's soundstage, but not all of it, and rendered in a pleasant and inoffensive soundscape unless your reception is poor [then it gets ugly.] And also there's a subwoofer or something providing more bass than Nana's kitchen radio ever did. It becomes very listenable, for long periods.
With a good recording, it 'rounds off' the sound so that it's not too piercing, too harsh, but individual instruments [especially pianos and some strings] and sometimes percussion can get beyond desired peaks or harshness. It may benefit from EQ? With a bad recording, it can bring out the worst of it. I use my BL-05s amped, foamed, and with high-quality sources, and it seems happiest there. With decent source material, it retains at least a basic coherence, and often highlights the instruments that are supposed to be. It's good with good sax, woodwinds, and basslines. Hit-or-miss on rendering acoustic strings, harps excel, surprisingly good with bells. Sometimes the sub-bass or percussion is very encompassing at the L-R poles, whereas the bells and treble strings seem 'higher' in the soundstage.
