Review: Truefree B1 - A Bearded Review - Truefree B1 Review - A Bearded Review A no-nonsense review of the Truefree B1 on-ear headphone First Impression The look of these on-ear earphones is... Interesting. They aren't like your regular IEM (in-ear) or headphones (over-ear). These have speakers that point toward your hear canal but sit on your earlobe. There is absolutely no audio isolation with these. If the volume is high enough, others can hear your audio, albeit, it would not be distinguishable by others, but still, they can hear it. Obviously, if you reduce the volume, you'll still hear the audio without others eavesdropping or being annoyed. Feel I personally like how these feel on the ear. Headphones can feel heavy over time. Earbuds can be a pain in the ear. These just hang like clip-on earrings without the pinch. They have metallic shine on the speaker and touch ends with soft silicone connecting them. I don't see any reason why you couldn't wear these for hours, unless you just don't like the feel. A bonus if you wear glasses or hats, these do not interfere with either. Audio Audio Codec-wise, they only connect with SBC (non-HD) or AAC (HD). These are default BT audio codecs that nearly every audio BT device can connect with. These are not high definition codecs where you won't hear the specific instruments in an orchestra and other audio. With that, they sound decent, loud enough for normal phone calls, listening to music, or listening to audiobooks or whatever you want to listen to. EQ Control The EQ function worked well. While you won't get amazing bass, you do notice it is there and provide nice sound. I've set my EQ to Rock and it sounds good. Phone Calls After making a few phone calls, no issues were evident. No one complained about being about to hear me speak. I could hear them without issue as well. Truefree App Interaction The Truefree app appeared to well with this set. Configuring the touch controls was easy and each touch function worked as you would expect. This is an improvement over some prior Truefree sets I've tested. With that, the touch pad on these is on the rear behind the ear. After getting used to the positioning, no issues with touch controls. My only suggestion is to instead have the touch controls on the inner ear section were the speaker is. Pressing the back of the set, pushing the earlobe moved the set and earlobe. It was fine, just felt uneasy if you aren't being careful. Moving the touch control to the inner part of the set would be more stable as the earlobe provides additional support. Battery Life First opening and using these earphones, they started at about 86% and whilst typing this on my phone and listening to DOOM (2016) OST, Rebel Galaxy OST, making phone calls, and now listening to Brothers of Metal, they are now at about 70% battery life. 15% in about an hour or so isn't too bad. Conclusion I'm a fan of this form factor. They are comfortable without being overbearing, weighing your ears down, and can remain for a long time without pain. They won't fall off if you're banging your head, running, working out, etc. An improvement of the app with the earphones makes this set a reliable and dependable set to choose. If you want audio without the pain of IEMs or the bulk of over-ear headphones, this is a solid choice. In addition to the above, the price is right. Currently, they are $40 on desertcart.
Review: Lightweight, crisp sound, customizable and responsive controls - I have been wearing them all day for over a week and find that they are light and easy to wear all day. I saw this design and wondered how these open-ear clip headphones would feel and sound. I am glad I did, because they are now my favorite open ear headphones. Left and right are marked on each earphone. When I put them on, it took a moment to find how they fit best and then I was very happy to find they are nearly imperceptible to wear. I don’t feel them at all. At the same time they sit securely on each ear! I have worn them while working out and had no problem with them moving at all. The sound quality is fantastic. Still, I could hear ambient noises, so wearing these while running water for dishes or vacuuming made them hard to hear. However, the volume has range! In a quiet setting, I am happy at 20- 30% and have room to spare if surrounding sounds are louder. I get a true 5.5 hours per charge and an easy 3 full charges from the case. The little oval case is about 2.5” long x 2” wide x 1” thick. It is like a rounded skipping stone that easily fits in the palm of the hand. The case recharges quickly using USB-C (a separate USB to USB-C cable comes with the case). I easily synced them with my phone, turned off phone Bluetooth and then quickly synced them with my computer. With Bluetooth on for both, the headphones work with whichever is playing sound. As with many headphones that pair to multiple devices, the one with sound takes over. If I turn off either device Bluetooth or “dual device connection” in the APP, then it will only connect to one at a time. I have just taken a phone call on the headphones and was told I sound very clear. They are IPX4 (meaning they resist water splashes from any direction but not immersion in water or from jets of water) making them suitable for everyday activities, plus workouts and bathing. Further, the app has a setting under More Functions called Drainage Function to blow out any moisture that may have made it into the earphones. In the APP (on my phone, installed, signed in, and paired to the B1 set), I navigated to settings and checked for any Firmware update for the headphones (there was not one). That took only a moment. Then I tried out the different preset equalizers (EQ) and even made a few of my own. There is a wide range for adjustment to sound preference. I also went to a very quiet room and performed the hearing test. This generated a personalized EQ to my terrible hearing (lots of tinnitus). After choosing an EQ, I checked the charge state on each headphone - which can be seen in the APP. Now, about the APP specifically: While the APP is not required for normal headphone use, it does allow updates to the firmware, seeing headphone specific charge state, and personalizing the EQ and touch settings, etc. FYI, when the APP is opened it creates a new instance for itself in Bluetooth settings (mine says “BT8932D”), close the APP and that goes away. The APP allows sending issues to tech support (under Help and Feedback, pressing the avatar at the upper left corner) and also performing Firmware updates (in settings found at the upper right corner), so any little issues that arise in the APP get addressed and the headphones get updates. Once signed in to the APP the first time, it does not need to be done again. Each time the APP is opened, I quickly “Accept” and “Connect Device”. I watched the video in desertcart Qs on how to get to the register screen.( I think after selecting accept, I clicked “forgot” at the bottom and that is where the register option was. Enter email, enter a “letter only” password, click to get a code sent to email. Enter the code in the minute allotted, view the terms again and click Register. Try again if it does nothing. It will work after a few tries.) The APP lets me see the charge level of each earphone. I find this useful when deciding if I should charge them and use a different pair when planning on doing some things. The APP offers many preset EQ to select from as well as offering a customizable and savable EQ option. This makes me VERY happy, and I have been refining my own custom settings to suit my hearing! Game mode and dual device connection and be turned on/off in the APP. There is also a place to customize the touch settings. I love that I can CUSTOMIZE and DISABLE ALL TOUCH CONTROLS here! I have long hair and, when wet, I accidentally stop, play, or turn sound up or down. Disabling touch on demand is the solution. There is also a hearing test to personalize the EQ. This is very cool as it tests hearing sensitivity across a spectrum of sound frequency types in about 2 minutes and used this to generate a personalized EQ setting. I would love to learn more about the tweaks made based on my weird hearing!

love them...get lots of compliments when wearing them and questions about the sound quality and they are one of the best clip ins I tried and I tried many..sound is good considering they are not in ear....and for a change the touch control almost works...(my fingers and talent for sensory touch buttons is not compatible so I usually struggle...but with these I sort of manage...the app is a bonus too..free of course..)
