  • Great Wireless option for 7HZ Dioko
Style: 0.78 2pins
Bought this for the purpose of converting my 7Hz Dioko to wireless. The connect is tight with no excess gap. The earphone does fit inside the case. Unfortunately the case is lacking battery life indicator. The App control is not great to use.

  • Great Find
Style: MMCX
I use this with the Shure 215 earbud. As a stage user I really like the headphones and these wireless adapters are an excellent fit. They have built in microphones, which though not the best they are sufficient. I like that I can connect in either earbud or headset mode to maximize bandwidth based on my priority. I sometimes find the wireless audio quality subpar - especially when connected as headsets - as well as overcompressed. I also like being able to connect only one earbud at a time. I have been using these for over a year and would definitely buy these again. ... show more

  • VS TRN BT20s Pro: Future of IEM True Wireless Looks Bright! (Update Regarding 0.78)
Style: MMCX
I’ve owned these for a few weeks and am very pleased so far. I had the TRN BT20s Pro before getting this model. They both approach a true wireless IEM in the same way, but FiiO’s execution is superior in most ways. Here’s how they compare: Sound: Arguably one of the most important characteristics when converting an IEM to true wireless. FiiO stands out for raw power, but also clarity and extension in both treble and bass are better than the TRN. Also the typical bluetooth hiss is very quiet on both but much less prominent in the FiiO. Lastly the microphone quality on FiiO is significantly more clear than the one on TRN. Please note, no bluetooth technology will outperform a physical connection. With FiiO, I mainly notice some small details missing from the upper treble and a slightly compressed soundstage. Fit/finish: The FiiO lay more flush against the back of your ears, but I find the hooks to be a little short and feel more like they dangle over my ears instead of wrapping around. Here I think TRN takes a slight advantage, but your experience may vary depending on ear size and IEM. Features/Versatility: FiiO has a large advantage because there is an accompanying app that lets you change the button configuration, choose from preset EQ settings, adjust volume, and is open to future firmware updates. Also FiiO has a more powerful integrated amp, which plays well with less sensitive IEMs. TRN misses big here but has one killer feature, the hooks can disconnect from the battery pack. This means you can buy extra hooks with different terminals (MMCX, 2 Pin, etc) without having to buy the full unit or adapters. FiiO does offer a 2 Pin version, but as of writing this review it isn’t available on Amazon. So you may have to consider buying MMCX to 2 Pin adaptors, or resort to buying from another marketplace. Carrying Case: TRN and FiiO took very different approaches here. TRN made a pouch, covered in fabric and closing with a zipper. It’s convenient for throwing in a bag, but doesn’t exude a sense of quality. There is a nice pocket inside the pouch to store accessories (something I miss when using the FiiO). On the negative side, there is no battery level indicator on TRN’s pouch, and larger buds need to be rotated to be able to fully close the pouch (This may be a deal breaker if you have a 2 Pin IEM). FiiO has an anodized aluminum case that opens with a magnetic latch. It's a nice presentation, but the finish may scratch over time. The IEMs sit in a nicely sized rubberized pocket. Lastly a 3 light indicator of charge state is a useful addition. My only gripe other than not having a pouch for accessories is that the magnet used to align the hooks doesn’t seem very strong. On the TRN I felt like I could almost drop the hooks and they would slide into place, with the FiiO it feels like a conscious effort to make sure the hooks are seated and being charged. Both use USB-C charging ports and neither have Qi wireless charging. On a side note the FiiO app is what makes me most excited here. It is clearly in the early days, the “Guide” tab is still blank on iOS. But I’ve already seen a firmware update come through, so FiiO is clearly working on improvements. In the future I hope to see custom button configurations, custom EQ settings, improved call clarity and maybe even someday an active noise canceling feature. (Update): I liked these enough to get a 0.78mm version. Unfortunately this has a serious design flaw. Instead of having the pins come out of a rectangular cross section, they protrude directly from the round ear hooks. This looks nice, but does not follow the design of 0.78mm cables. As a result, most 0.78 earphones will not fully seat and can easily fall off of the hooks during handling. I'm knocking off a star for this oversight. ... show more

  • Lasted almost 1.5 years
Style: MMCX
Purchased in Sept 2021 died Jan 2023. Overtime use Pros: sounded pretty good (mated with fh3 and Shure 425), functionally was simplistic and rarely gave a fuss. Cons: - Case doesn't secure shut and with an "power on when case opens feature" you can find your devices pairing unknowingly and leaving the hook batteries dead. Which can be extremely frustrating when you need them charged. [Always have a backup/secondary setup] - Prongs in case protrude and hooks can wiggle slight enough to damage them. - App is a novel idea, but pointless and terrible. - Kind of wish the hooks had a little adjustability, but not a deal breaker as they were comfy majority of times. All in all, I'm not upset by the purchase but I really do wish they would've lasted longer especially with the level of care taken to protect and maintain these. Will I buy again? Most likely not. They're nice but longevity matters and discovering near drained or totally drained hooks would leave you scrambling if you don't have a backup with you. Lastly, while the sound quality was pretty good, there's comparable, if not better, options out there ... show more
