FiiO has designed the pair with dual high-density neodymium magnets that deliver a high-sensitivity design to the JT7. Through precise engineering, FiiO has utilized a chip-grade 28nm manufacturing process to seamlessly integrate the diaphragm and voice coil. FiiO JT7 is a premium-sounding over-ear headphone that delivers true high-fidelity sound without breaking your bank!! Enjoy the finest details in your favourite music with great comfort available on the FiiO JT7!!

Self-Developed Large-Sized Planar Magnetic Driver:-

FiiO has developed a large 95x86mm planar magnetic driver for the JT7. This driver is designed from the ground up with in-depth R&D for different components, including the diaphragm, voice coil, and magnetic circuit. Being totally in-house developed, the driver has guaranteed consistency and promises excellent sound quality. It utilizes a 3µm ultra-thin diaphragm that offers light and agile movement, ensuring crystal clear sound response across a wide frequency range.

Rich and Dynamic Bass with F.E.S:-

FiiO JT7 features FiiO’s self-developed F.E.S(FiiO Elastic System) design on the driver diaphragm. It incorporates multi-dimensional textures on the surface, which are similar to the surround ring textures on a dynamic driver. This unique and innovative technology increases the diaphragm’s elasticity. Compared to traditional planar drivers, this innovation allows for precise control over internal stress, resulting in swifter movement, ensuring rich and dynamic bass response. The bass is punchier and has lower distortion compared to traditional planar drivers.

Crafted With Full Precision:-

FiiO has crafted the JT7 with ultimate level precision. FiiO has utilized a 28nm chip-grade manufacturing process to achieve a seamless integration between the Voice coil and the Diaphragm. This not only yields extremely fine coil wiring but also boosts the structural integrity and durability of the driver.

Strong Magnetic Field For Enhanced Performance:-

FiiO JT7 features a strong and sensational magnetic architecture. The pair adopts two-way heterogeneous high-density magnets that generate a strong magnetic field, ensuring greater efficiency with the pair. The JT7 achieves a high-sensitivity design. These magnets deliver robust and ample driving force to the planar driver, enabling a loud and fuller sound from even moderate sources. You don’t need high-end DAC/AMPs to get the best out of the FiiO JT7, with its high-sensitivity and low-distortion design, enjoy the pair as you like!!

Lightweight, Foldable Design:-

FiiO JT7 has lightweight ergonomics and a foldable design. The pair weighs just 318 grams, and it is super comfortable to wear for long listening sessions. Additionally, the pair has a multi-axis headband that rotates in multiple directions, helping the users find their perfect fit. Furthermore, the pair has a foldable design that will help users carry the pair anywhere they go with ease. FiiO JT7 also has replaceable headband cushion and ear pads, users can customize the set to their liking.

Detachable Cable Design, Two Stock Cables:-

FiiO JT7 has a detachable cable design featuring dual 3.5mm connectors on the headphone side. FiiO includes two stock cables, one terminated with a 3.5mm plug, the other with a 4.4mm termination. FiiO also includes a 6.35mm to 3.5mm adapter for easier pairing with different portable as well as desktop sources.

Forget Adventurer 5M , This is the true and easy to use beginner machine
Set name: Ender 3 V3 SE
This is my 3rd 3d printer. Once I spent about 45 minutes assembling it has been printing nonstop since the amazon driver dropped it off, these are the best for reliability and perfect for hobbyists. It is not the quickest machine out there, but it makes up for it with a quality print good price as well.

One - Month Review
Set name: Ender 3 V3 SE, Set name: Ender 3 V3 SE
First - I wrote a out of the box review - I do not know if this review will replace the old review or compliment it. Just in case this review replaces the old review - I will repeat a few of the important points from the previous review. I must also say it helps a great deal if you are already familiar with Ender because about 80% or more of the machine is built the same way as the older models. If this is your first Ender - read the instructions and check to make sure you have all the parts. Placing the parts where you can easily tear open the bags and not having to search for a part cuts down the assembly time. While the assembled printer takes up a small footprint - give yourself room to work. This is my 3rd printer - my first one I made from scratch. It took about 2 weeks to get it assembled and another two weeks to get it to print properly. Most of that time was spent modifying the Martin software so it would run my machine! My second one was an Ender V1. It took me about 90 minutes to assemble and about 30 minutes to get it to work. Over the years - I modified it to the point it was virtually impossible to tell the difference between it and a V3. I replaced it because a least one of the motors was going bad and I did not want to do the repairs. I picked this printer for 3 reasons 1) it was on sale, 2) I am now wheelchair bound and needed a printer that did not require too much assembly, and 3) I had worked with Ender before and knew how they worked. I was able to keep some of the old parts from the old machine (but threw most away). Everything was packaged well, but the small parts are in plastic bags that you have to tear or cut open - so be careful you do not lose any parts! There are only three parts to be assembled. They are the base, the frame, and the screen. I had no trouble getting the machine together - did have some trouble getting it to work. I was never able to reach customer service which ranged between "Who are you Kidding?" and "Did you really expect any?" I did some internet searching (there is lots of stuff out there - many are good YouTube videos). I found I needed to do an update - it got a bit complicated here. Part of the update was done using the hidden slot on the LEFT side of the removable screen and part was done using a SD card on the LEFT side of the Unit. (Ender does NOT tell you this on their website!). I was already angry when I tried their slicer and it did NOT work - after not being able to get customer service again. I deleted their slicer and used my Cura. After doing a few prints using Cura (which works fine) a couple days later, I reinstalled their slicer and did some troubleshooting - I found I had a setting wrong. I use both Cura and their slicer now because of the differences. Each one has some features the other one lacks. One example: The Cura has a large number of preset configurations, and it is easy to save a custom configuration. The Creality titles the g-code with a filename that includes the estimate print time. I tried customer service and actually someone! They did give me the manual settings for generic Pla - when I asked how to save those settings they send me to a useless link. I will research how to save one day - but will use my Cura for generic pla until then. What I like about the machine. 1} While it is nosier (a trade-off for higher speed) - it is still much quieter than the original Ender I had before modifications. 2)The new ribbon and print head are a big improvement. The filament is easier to change, and you can easily make prints with different colors! I do not miss the bowden tube and individual wires at all! 3) I like to put my prints on a card. The old machine used a micro-SD card - and I quicky bought an adapter! The new machine takes regular SD cards and no adapter is needed! 4) I really like the automatic leveling feature. There have been times I have spent hours getting my manual table set the way I wanted. So far - it has worked great. I have only made about 50 prints - so I cannot tell you how reliable it is in long term use. 5) The quality of prints is much better than my old machine. I am not sure whether this due to being a better machine or the stepper motor needing replacement. What I do not like: 1) The SD card has to be put into its slot upside down. 2) The controls and the SD card slot are all on the left side of the printer. I think putting the computer connection and the SD card would have been much better on the front of the machine. 3) Updating is like putting up a Christmas tree. The firmware is done with a hidden C connector on the left side of the detachable screen (this is like putting up a Christmas tree). Fine details on display etc. are put in using the SD card (this is like putting the lights on the tree). Once you figure out what goes where - it is the easiest printer to update I have had. 4. This one is a mixed bag. I do not give their customer service good marks - but the fact I found solutions on the internet was a good thing.

The K2 SE is a great entry level printer. Don't let the naysayers get you down!
Set name: K2 SE
I bought the K2 SE because it was inexpensive and I wanted to get into 3D printing. I had a Creality laser engraver that worked well, so I figured I'd go with the brand I knew. I bought the additional enclosure because I was planning to use this in the garage where my wood shop is, and I wanted to keep some dust out. I have been pushing this thing pretty hard for three months now and it has not so much as looked at me cross eyed. It takes everything I throw at it. The quality seems to be there, as nothing is wearing out. I have a little superlube oil and grease to keep up the maintenance, and I suspect any failures people report have been on unmaintained machines. If you're the type that drives your car without changing the oil, 3D printing is not for you. A quick note on 3D printing, for the uninitiated. When you see the one and two star reviews for the K2 SE, make sure you read why the reviewer is leaving the low rating. "Doesn't come with filament" - if you're not buying a combo with filament, none of the printers on the market come with filament. "Makes bubbles and pops when printing" - this is wet filament and not the fault of the printer (dry your filament). 3D printing is not a set it and forget it proposition, at least not at first. It requires a little skill (that can be built), a little knowledge (the U of Tube), and a little patience while you learn how to use the machine. Now for the machine itself... The print quality surprised me as a first time 3D printer user. I have purchased 3D printed items in the past and the lines were not something that impressed me. The K2 SE prints pretty much the same quality as the higher end Bambu Labs printers. The speed is all I could ask for, and I have fed this thing all kinds of PLA, PETG and TPU from Creality, Sunlu, Polymaker and AnyCubic without a problem. Any issues I have had have been the fault of the operator (me) not knowing I had to dry PETG before I use it. I have a Creality filament dryer now and dry my PETG right out of the package, then store it in an airtight container with dessicant. I have two printers running dried PETG sitting behind me right now and they're doing great. If I have a single complaint about the K2 SE, it's the bed size. At 215 x 220 it's smaller than the industry "standard" of 256 x 256, and if you get some of the larger prints that are designed for a "standard" sized printer, they won't fit the build plate. But I knew that coming into this, because they advertise the size right up front. Overall, I'm happy with the K2 SE. It was an excellent entry level printer and I have learned a lot from using it. I may even buy a second to add to my growing farm.

Creality K1 SE - Prints great with stock settings - needs a side spool mount
Set name: K2 SE, Set name: K2 SE
I bought the Creality K1 SE a little over a week ago. I had an Ender 3 S1 before this printer. The K1 SE is so, so much easier to print with right out of the box! I definitely recommend it. It's a good way to get the improvements that were built into Creality's K1C, but at a nicer price. Plus, you can install your own version of Klipper if you want. I've printed 10 or so things in PLA and PETG, and I haven't had any failed prints. The automatic bed leveling has just worked. I have not had any problems with bed adhesion. On the Ender 3 S1, I only used a textured PEI plate, but the smooth build plate on the K1 SE works fine. The extruder cooling fan also seems ok for what I've printed so far. I printed an overhang test and the 75 degree overhang looks fine, but it had trouble at 80 degrees. The bridging test looked ok. (The longest bridge was only 25 mm on that test however.) I've put the printer in a soft-sided enclosure that I had used for my old Ender 3 S1. (It's easy to find similar encolsures.) The LEDs on the K1 SE are bright enough to see inside which is something that I was concerned about before I purchased. However, this enclosure makes it difficult to access the back of the printer where the filament spool is mounted, so I designed a mount that clamps onto the side-bar - see the pictures. The files are on Printables - "Creality K1 SE Side Spool Mount".

Almost Good
Set name: K2 SE
The nozzle cleaning is completely ineffective. The wiper pushes material up the sides of the nozzle and melts onto the nozzle. The result is the nozzle leaves burnt debris on the prints. The calibration before each print only probes 5 points on the bed and the results are not satisfactory, with the nozzle being variously too close or too far from the bed. To adjust the z offset you have to go through several menus and the machine seems to not remember where you set it last time. Print quality is good except for VFAs. Part cooling fan is very loud at full speed.
