Shures have always been good propositions for standing the test of time. When the SE846 was launched, they were $1000. Look at the Shure website now, they're still $1000. They don't depreciate in value.
I have a question. I'm planning on going full wireless and am considering the Shure True Wireless Secure Fit Adapter to pair with my SE846. I wanna use them will I ride my bike to listen to music and answer calls. They're expensive as hell, I can buy a pair of Apple Earpods Pro for that price almost.
Anybody have any experience with the Secure Fit Adapter?
Not with that exact product but I've had lots of issues trying my new Linsoul TRN BT20S Pro with the SE846. The Shure unit, the TRN BT20S Pro and the new Fiio UTWS3 all use the same Qualcomm QCC3020 chipset which limits you to SBC, AAC and plain aptX codecs. The TRN and Fiio units are less than half the cost of the Shure, but right now I wouldn't recommend any of them. Other users of the TRN unit have reported the same issues I'm seeing, and the Fiio units are just starting to ship in volume with early users reporting some of the same issues.
I was using a Fiio BTR5 with a balanced MMCX cable and my SE846 but like any battery device can, it experienced an overheat causing the battery to bulge and pop the front glass off the body. This of course happened 1 week outside of warranty, but Fiio support is willing to repair the BTR5 for a minimal surcharge if I can return it to them in China. I will get it sent shortly, but in the meantime I've been trying to get the TRN to work reliably. Alas no success.
So on Jan. 4th I decided to go for a much larger unit, the Fiio Q5s TC. It's a amp/DAC with dual AK DACs and a balanced THX AAA amp module. It offers Bluetooth, USB, line-in, TOSLink optical in and coaxial SPDIF in, as well as featuring a line out and both single-ended 3.5mm and balanced 4.4mm jacks for your headphones or IEMs. I bought a new Fiio LC-C 2.5mm balanced MMCX cable to go with the Q5s TC and am using a 4.4mm male to 2.5mm female adapter for now. I've ordered some 4.4mm connectors so I can build some custom adapters to use with the custom balanced cables I use on my Sennheiser HD800 and Hifiman HE560.
The Q5s TC is considerably larger of course, but it's been rock-solid connection-wise when roaming about my condo. The BTR5 would struggle when I was more than 10' away from the Bluetooth source and the TRN are just plain flaky with dropouts and loss of BT handshaking even while sitting or standing still. Of course the other issue with the Q5s is the cabling and the weight/size of the unit, whereas the Shure Secure Fit, TRN and Fiio units are considerably more compact. Alas the convenience of size seems to be overshadowed by the connection reliability issues.
If I was in your shoes, and even after I experienced a failure of mine, I'd recommend the Fiio BTR5 and at least the Fiio LC-C 2.5mm balanced cable. Much better codec support, better stability for the BT connection, great power output especially on the 2.5mm balanced output. Good luck on finding a solution that works well for your bike rides!
If you do go for the Shure Secure Fit adapter, make sure you can return it for a full refund. I suspect all three of these compact BT products are simple variations of the same hardware and hence all are experiencing the same issues. But again, I haven't tried the Shure unit so perhaps it's more reliable? To me the cost of the Shure is too high, just like it was with their original BT cables, the RMCE-BT1 and BT2.
I'm happier overall now that I went with the Fiio Q5s TC but it's considerably higher priced as well. It offers more power and also functions as a USB DAC supporting up to 768KHz/32 bit PCM and up to DSD512. I'd rather have the reliability and increased functionality that it offers.
