Bluetooth 4.2, Built-In Mic & aptX

With these Bluetooth cables from PlusSound, you can turn any IEM or headphone with removable cables into a Bluetooth device. They can drive IEMs with two-pin and MMCX connections (like the Massdrop x Noble X and Massdrop x NuForce EDC, respectively), along with full-size headphones like the Massdrop x Sennheiser HD 6XX and the Massdrop x HIFIMAN HE4XX planar magnetics. Made to order in Los Angeles, all cables feature Bluetooth 4.2 with a wireless range of 40 feet, along with aptX technology for a balanced output configuration, superior audio quality, and low-latency support. Great for making phone calls and using voice control, the built-in microphone delivers clear sound with wind noise reduction. The battery provides 10 hours of continuous listening between charges.

Recent Activity

I bought a pair of these for my Unique Melody Merlin's (yeah, they're old, but also great) and use with my Pixel 2. Pros: - I received exactly what I ordered, in a time frame slightly faster than what was anticipated - build quality is excellent - looks amazing - the two-pin socket fits perfectly in my CIEM's; nice and snug, but not hard to insert or remove - some have complained about the loud beeping; the fix for lowing the beeping volume presented by Plussound elsewhere in this thread does work, and at least so far, has been persistent. I have no issues with loud, painful beeping. - easy pairing, which has so far worked as expected - sound quality: these sound pretty good, meeting my expectations for audio quality with aptX. The character of my headphones is definitely preserved. More below in the "cons" section. - does work for phone calls, although I have only used this once and can't thoroughly evaluate Cons: - as described by others, there is a bit of a hiss with my sensitive (12 ohm) IEM's. I do not finding this problematic as I purchased this cable for my IEM's which I use in public, so there is already background noise and darkness is not required. I have definitely heard louder hiss with these IEM's on other amps, so for me, this is fine. - Bluetooth 4.2 with aptX. Because of these technical limitations, there is less latency than with SBC, but there is still enough latency that these aren't great for gaming. The sound lag is tolerable, but definitely noticable. Additionally, the sound quality is what one would expect for aptX; clearly not as good as wired with a good amp, with some less in fidelity, sound stage, and detail. I put this in the cons section in hopes that a future revision might adopt Bluetooth 5.0 and/or higher quality audio codecs like aptX HD, LDAC, and so on, but honestly, the SQ is slightly better than I was anticipating given aptX. - Uses a micro USB plug. Come on, this ain't 2015, upgrade to USB-C! Overall, I'm pretty happy, and got exactly what I expected/hoped for. I know the "cons" section above looks long, but it really isn't; if you are looking for a way to Bluetootherize your IEM's for working out, use in public, etc, these are a great choice and get the job done in style. If you want to preserve the highest of audiophile-quality experiences, don't get this, as there is a loss in SQ (which should be expected; you're buying something using aptX!) The SQ is better than I expected, and is competitive with the SQ I get using the Pixel 2 included USB-C dongle. I would definitely buy these again.
