Introduction
The Fragrant Zither (TFZ) is a company that I am very fond of. I absolutely loved their previous flagship, the TFZ Series 5 and praised it with very high word. It became one of my most recommended IEMs for those who desired a heavy bass impact, tuned for an exciting listen. Upon requesting information on the TFZ Series 7, they reached out to me to graciously provide a sample of their next model, the TFZ Balance 2M. I was ecstatic -- I can say that overall, the B2M has met my expectations for a TFZ Product.
This review will mainly focus on my perception of the sound, as I believe that is what most matters. I can assure you, the unboxing experience was pleasant and definitely contributes to the overall feel of the IEM. It is very pleasing to see companies stepping up their packaging game (P1). However, I will do brief memory comparisons versus other IEMs I've had experience with. I believe sound signature comparisons are important in reviews for people who are hoping to purchase their next IEM, to have a reference as to what it may sound like.
The TFZ Balance 2M
BUILD / ACCESSORIES
The cables disconnect and connect via MMCX. In my sample unit, there was a slight QC issue regarding the right MMCX slot not being solidly glued into the housing (opened it myself to fix). The Fragrant Zither acknowledged this and said that they would address the issue with their QC person, so hopefully this isn't an issue in the future. The Balance 2M comes with two cables -- one braided branded by TFZ, and another silvery-white braided cable that has no direct branding. I found myself a big fan of the spare silver cable, as it has memory wires that default to a 'hook' shape to wrap around the ear without issues. The default TFZ cable is definitely a little weird to me, in the regard that its 'memory' has it returning to a STRAIGHT position. Not entirely sure what this was about -- the cable has to be cinched up to your chin to keep the cables over your ears. Oh yeah, there IS a cable cinch!
The case that comes with the IEMs is very big -- you can probably fit any DAP imaginable in there. However, it is very spacious and contains all the accessories for the IEM. The zipper is smooth and never catches, so using the case is actually a pretty pleasant experience.
SOUND
Bass
Mids
The vocals of the Balance 2M are much improved over the TFZ Series 5. They have a presence in the overall frequency response, but they don't really come to the forefront of the sound. The lower mids fall in line cleanly transitioning from the mid-bass, without too much bleeding between the two, which tends to be a big issue in cheaper IEMs with a bassy signature. However, not everything is perfect here -- the very flat presentation of the Balance 2M feels to be a little too linear. The Balance 2's lower mids feel to be in a good spot, but the upper mids don't really have that hump that gives vocals a biting edge. As a result, I found vocals to be a tad bit veiled and dull. Male vocals with warm resonating notes sounded fine, but female vocals didn't have the same energy that the TFZ Series 5 did. On the other hand, the overall mids have a good quantity that lines up well with the rest of the spectrum -- not recessed, but not in the forefront of the signature.
Highs
The Balance 2M has a nice presentation of the lower treble. It's never going to be sibilant (also a byproduct of its sloping upper mids), and will never have you cringing from high pitched treble blasts. The treble has a slightly laid-back position, so the signature is conclusively a relaxed sound. I could listen to this IEM for hours without treble fatigue, but this is not without its downsides. Some may desire a more prominent treble peak -- those who love the energy of the TFZ Series 5, the Balance 2M has a bit less. It's a non-fatiguing listen, but also not very engaging. Now, the upper treble. This is where I feel the Balance 2M has its weakest link, similar to the Series 5. The upper treble seems to fall off a cliff, resulting in a 'small', boxed-in sound. The treble isn't as airy as I would like, as it doesn't extend far enough to get those unheard details. So yes, the TFZ Balance 2M has sufficient details and energy in its treble, but it's definitely not a detail monster. It is the type of treble that will envelop you, but it won't really take you for an exciting trip if the music calls for it.
Overall Impression
The Balance 2M seems to be a very slightly downward sloping frequency response, characterized mainly by its thick resonating bass and relaxed high notes. It's a a very warm sound, and might have a slight dark veil to the overall sound due to its laid-back upper mids and treble. Once again, vocals are not the primary focus of the sound signature (unfortunately). This is where personal taste kicks in, as I know many people love this type of signature.
I personally enjoy the Balance 2M a lot and think that the original Balance 2 (non-detachable cable) is a fair value at the recent $119 on Massdrop. I think the $70 price difference between the non-detachable and detachable cables is a little steep, but I haven't felt the B2 to really say much on how the build quality is different. The major gripe I have with the Balance 2M is the lack of treble extension, which I really hope is addressed in the B4 and B6. If treble is more extended, this IEM would be more competitive.
COMPARISONS
Mee Pinnacle P1: The Pinnacle P1 comes in at the same price range as the TFZ Balance 2M, but the two couldn't sound any more different. The Balance 2M has a much more visceral rumble to the subbass, and a harder midbass punch. However, the P1 has a cleaner low-end and sounds faster in decay. Vocals sound a lot more isolated and separated on the P1, which will make the Balance 2M sound veiled in comparison. The P1 is brighter and more up to par in treble than the Balance 2M (a good thing), and enhances that with a fantastically detailed top-end extension that sounds airier. The Balance 2M's treble feels a bit suffocated in this regard.TFZ Series 5: These two are similar sounding IEMs at great entry level prices. The S5 has a cleaner mid-bass with similar subbass extension, but can definitely be more punchy than that of the B2M. The B2M has a more linear bass response, so the less emphasized midbass may actually highlight the subbass extension. However, lower mids on the B2M are more 'forward' to the S5 in terms of quantity. Vocals on the S5 sound more detailed and less veiled due to the upper mid hump that is missing on the B2M. Treble is more or less the same in terms of extension, but the S5 does have some cases of sibilance/harshness. If you love the TFZ 5 signature but wanted something more tamed and laid back, this could be a very good choice for you.
