Tanchjim BTN82 Bluetooth Cable review: With Freedom and security

SOUND:

I tried the BTN82 will a few earphones including the TRN v20, TSMR 2 and NiceHCK NX7. The Bluetooth module has a very satisfying overall sound delivery as there is little to no distortion and it sounds close to the potential of the earphone.

Note decay of the BTN82 is a bit slower than when using stock wired cables of the respective earphones, resulting in fuller and more prominent bass notes with considerably more thump as well as adding warmth to the presentation.  This works well with balanced sounding earphones such as the TSMR 2. Mid range has very good instrumental clarity and vocals sound very accurate. Just like the bass region, decay speed is marginally slower giving the notes a fuller and meatier body. It sounds lush, but still aptly accurate. It is not logical to expect wired level of micro details and transparency here, but the BTN82 manages to deliver most of it. Layering and separation is good and has a sound stage bigger than the wired mode, and that is a big plus.

Based on my experience as well as few of my audiophile friends I know that wireless earphones doesn’t have very good treble extension. I have past experiences where wired earphones from Brainwavz barely had any treble to talk about, this earphone does better than them wirelessly. But the BTN82 manages to deliver nice treble extension and details, although the treble region lacks a bit of definition and sharpness irrespective of the earphone used.

Pairing, devices:

I tested the BTN82 with several sources. Even though most DAPs these days have Bluetooth, many mobile phones have lost their headphone jack and need wireless connectivity desperately. I used my Galaxy M30s, OnePlus 5 and Plenue R for streaming. All paired with ease, just hold the power button for a few seconds, wait for the light to blink red and blue, the BTN82 is ready to be paired. Now find the BTN82 on your device, select it and you are good to go. Pairing it with mobile phones lets you see the charge percentage of the BT module.

Plenue R ($339) (8/10): Paired with the Plenur R, the BTN82 makes the earphones sound nearly as good as wired. The loss in details is not bothersome as the BTN82 maintains the native qualities of the earphones. Due to the dry sound signature of the Plenue R all the earphones sound cleaner compared to other sources.

Galaxy M30 Phone ($230) (6.8/10): mobile devices do show their limitations as my M30s clearly lacks good amount of micro details and clarity. The bass sounds bloated, it lacks some sub-bass presence but over compensates with a mid-bass. Mid range sounds slightly dull, vocals lack a bit of bit. Treble region misses on some extension and details. Surprisingly the overall stage size is bigger than the Plenue R.

OnePlus 5 (7.5/10): Pairing with OnePlus 5 delivers better details and clarity compared to the M30s but is slightly drier and congested compared to the Plenue R. It is the native sound properties of the mobile phone which holds the key for the BTN82 sound quality. If the device is a Samsung Flagship or a recent generation, expect wireless sound quality as good as dedicated DAPs.

Pairing, earphones:-

I tried a couple of earphones with the BTN82 with different sound principals. The comparison is with the 3.5mm cable that comes with the earphone.

TRN V20 ($24): The TRN v20 with hybrid principal pairs exceptionally with it. The best of the lot as it gets very close to the wired sound. There is little to no difference with the slam size and rumble. It maintains nice body and good texture. Vocals get slightly thicker and fuller notes making things more engaging. Instruments have nice attack and bite to them but slightly miss out on the micro details. Treble has good amount of details and spark, the extension is not very good. The stage size is larger than it is with the stock cable. 

TSMR 2: Pairing the BTN82 with TSMR 2 results in a very interesting sound output. The overall decay speed gets slower and the TSMR 2 sound lush and smoother. The bite of the notes gets softer and makes it less attacking. Bass gets meatier and has a bigger slam. It loses a bit of definition while gaining a bit more texture. Vocals sound slightly more forward and a bit thicker. Instruments dont have that much of attack or details to them. Treble is well extended but still lacking compared to the wired version. The stage size is slightly smaller than the stock cable.

Comparisons:

KZ Bluetooth Cable [$15]: Compared to the KZ cable, which is equipped with BT v5.0, the BTN82 delivers better and fuller notes. The bass of the BTN82 is more defined with improved details and note accuracy. The midrange of the KZ sounds dull and less accurate. The timber is slightly off with an unnatural finishing to the notes. Treble region has slightly better extension but the same unnatural presentation persists. The stage size of the KZ cable is marginally better than the earphones’s stock cable but the BTN82 has better 3 dimensional expansion. Presentation of the treble region is similar to wireless cables. 

The BT v5.0 does not translate into better quality here as the BTN82 manages to outperform the KZ BT cable by a sizable margin. The biggest flaw of the KZ cable is its issues with connectivity. It drops frames and lags even when the Source is 3-4 feet away.

The overall sound signature of the KZ cable is dry and the stage feels hollow with most of the instruments lacking bite and transparency.

TRN BT10 [$30]: The TRN BT10 too is equipped with BT v4.2 and is similar to the BTN82 when it comes to sound signature. The problem with the BT10 is that it is unable to keep up with high BPM songs and the latency is considerably worse than BTN82.

BT10 delivers a balanced sound signature without emphasizing a particular part of the spectrum. It does lack some sub-bass extension, mid bass is not very prominent with slightly lesser texture and notes have hair slower decay speed. Mid range is well under control, vocals sound lush but lacks some sharpness and transparency when compared to the BTN82. The treble region doesn’t have the extension and details of the BTN82. It lacks some micro details and notes transparency and the stage size of the BT10 is slightly smaller in every direction.

Conclusion:

If you are not absolutely critical about sound quality, the BTN82 is one of the best options in the market. You barely missout on anything,  Till this day wireless connectivity has not been able to provide the full spectrum of 20hz-20khz with equal precision and balance as their wired counterparts but the BTN82 get really close.

It manages to maintain fantastic transparency and clarity across the spectrum and doesn’t mess with the native qualities of the earphone.

If you have a wired 2pin earphone and want to go wireless without breaking your bank, delivering reliable connectivity, and maintaining high sound quality the Tanchjim BTN82 should be your top pick.
