Hello everyone! If you have been following the development of Project Muse you’ll remember that Eve sent out some samples of the Cleer Flow II to some select testers to see what we can use from the Flow II on the Muse. The testers were required to write a review of the headphones and everyone did an amazing job at it, but the reviews are very long one it would take quite a while to read them, therefore I sent a poll to the testers so I can make a summary of the reviewers’ opinions which will be quick and easy to understand.
Comfort and Build Quality
One of the main complaints with the Flow II was that they aren’t very comfortable. On the poll, on a scale from 1 to 10, the average rating was 6.
45% of the testers complained about feeling pain while wearing the headphones, and only 27% felt that their ears got uncomfortably warm. Another 27% of the users felt that the headphones were uncomfortably heavy. The most likely cause of this discomfort was the relatively high clamping force, which on a scale from 1 to 10, users rated it at an average of 6.5, 1 being the most uncomfortable.
The design could use some improvement. The average rating of the design for storage and storage was 6.5, which should definitely be higher once we make Muse. The build quality was decent, rated at an average of 7, but the votes on the looks of the design were split 50/50.
Overall, IMO we should not reuse the design of the Cleer since it isn’t comfortable and many users don’t like the look of the design.
The sound quality was decent but it could definitely use improvement. The average rating for the wireless sound quality was 5.9 and it improved quite a bit when using it wired, with a rating of 7 when using it wired.
The testers determined that the sound range was low on the lows and mids, which from some testing I found out could be fixed with EQ, but the EQ only worked when wired, although Spotify has an integrated EQ which works on wireless mode. Almost all users found that the sound quality increased when using them wired, which is likely caused because of a better DAC and Amp on the output device.
The microphone definitely needs improvement, the users gave an average rating of 5.
The ANC was rated at 7.2, and several users mentioned that the pressure from the ANC was uncomfortable at first, but they got used to it after some use.
The ambient passthrough mode was rated at 7.1, but it was unusable if you have a fan beside you or if there is a lot of wind since the mics pic the noise up and it sounds very loud and annoying.
The Google Assistant button worked with 70% of the users’ devices, but devices that did not have Google Assistant implemented natively did not work with it. It would be great if Muse replaces that with a button that summons whatever assistant you are using on your device.
The touch controls need a lot of work. The testers gave it an average rating of 4.3, and several found that they were almost completely unresponsive most of the time.
It was very easy to connect the headphones to a device. Testers gave it an average rating of 8.8.
Battery and Charging
The battery was very good on the Flow II. I ran some exhaustive tests on the battery life and found that at peak performance it lasted a bit more than 25 hours with full charge, and a bit more than 3 hours with just 10 minutes of charge. After several months of use the battery has degraded very little with the original number varying by just around 30 minutes compared to the original measurements.
All of the testers felt that the batter lasted enough, and the average battery lifetime was 22 hours per charge. The charging was also quite fast and all users felt that it charged fast enough.
Overall, the design of the Flow II shouldn’t be reused for Muse since it has too many flaws, but the drivers can be reused as long as we add a better amp/dac and add some EQ. The touch controls definitely need to be replaced, but the batter was excellent.
I’ll be working on improving this post, possibly adding pictures of the polls.
