iLuv Earphones

I’m writing a review about that goes against the spirit of Cool Tools in a way. While I love these headphones, the price is very reasonable, they aren’t necessarily “the best” of their kind. What I really want to evangelize is the idea of the flat headphone cable.

I love earbuds. I hate dealing with tangled cords. I would stuff my headphones in my bag, and they would come out in a Gordian knot. All the solutions proffered seemed just as labor intensive as untangling them afterwards, involved wrapping them so tightly I couldn’t help but think it was going to damage the wire or give it a memory (so it would revenge-tangle itself when I turned my head for a moment), or both.

Flat cables don’t “feel the need” to twist, and so drop them in the bottom of your backpack, pull them out and they’re ready to go.

I simultaneously bought MEElectronics flat cable earbuds and the iLuv on Amazon. I didn’t like the former as much; weird static-y shocks when I walked on my treadmill; the latter have the remote to pause/play/skip ahead, turn volume up and down and take calls w/integral mic.

I’ve noticed flat cables featured on SkullCandy and other brands; I’m sure an audiophile can buy $300 noise-canceling flat cable headphones. The main point for me is that the no-tangle principal worked great, look for it, then figure out what else you need and go from there.

Bose QuietComfort 15 Acoustic Noise Cancelling Headphones

I’m a test engineer for large tape libraries in a noisy lab. (It’s one of the best jobs in the world — making robots crash into each other at high speeds may not be the sine qua non of computer manufacture, but it’s just plain fun.)

Between the HVAC, the server farm, and the bot wars, it’s noisy. Needless to say, this affects my hearing — so much that my wife thinks my favorite phrase is “Would you say that again, honey?” After many false starts, I finally found a set of noise cancelling headphones that I can wear all day without making my ears sore, and are durable enough to last two years (so far).

With 20 test engineers in the lab using these, the bar is set pretty high. Collectively, my group has bought a lot of hearing protection, and these are the only ones that are durable, effective, and comfortable. The old adage “cheap, comfortable, effective – pick any two” applies here — Bose QuietComfort’s cost $300, but cheaper ones just don’t cut the mustard.

The signal processing in QC15s is excellent, but cheaper models come close. The real secret sauce is the comfort engineering – nobody else comes close to Bose. They are suitable for enjoying music, but that’s a secondary benefit. You can wear them for a full day, and your ears aren’t sore — that’s key.

If your employer won’t pay for these, buy them anyway. You’re worth it.

How to Build a Guitar: the String Stick Box Method

I’ve been making cigar box guitars for about five years, and this is the DVD that taught me what I needed to get started. Bill Jehle is a traditional guitar maker, and he made this video as a way to introduce people to the art of making more complex stringed instruments. His delivery is calm and orderly, and free of hype.

The video helped me over the hurdle of installing frets, which I had previously assumed was a monumentally difficult thing to do. I also learned about neck profiling and how to make the headstock. When I built my first guitar, it had plenty of problems, but it would have been much worse had I built it without the knowledge I’d picked up from viewing the video.

LinkeSOFT SongBook

If you like to sing songs and play along on your guitar, banjo, ukulele, etc. at a campfire, bar, church, etc., the tablet revolution has been a boon. No more binders to carry around! Instant access to lyrics and chords for approximately 1 bazillion songs!

The downside, though, is that the quality of the song transcriptions you find online are of widely varying quality. Additionally, the web pages that contain the transcriptions are chock full-o-ads, and as a rule, the best campfires are found where the internet access is the worst.

The answer to these problems is to curate your own collection of song transcriptions. The best tool I’ve found to do this is LinkSOFT’s cross platform SongBook.

SongBook allows you create and manage files for songs in the simple, plain text based ChordPro file format. It is easy to start with the transcription of a song from one of the online archives, and then correct / customize it within SongBook. Once the song is set up, it is easy to do things like change keys and display chord fingering.

SongBook has versions for both desktop and mobile platforms, and the mobile versions support DropBox for syncing. This makes it easy to utilize the strengths of each. I use the desktop version to create and edit song files, and the mobile versions for performances. That said, if I need to edit a song on the go, those edits get automatically synced thanks to the magic of DropBox.

The app does cost a few bucks. However, I have found it to be a good value. There are new functions being added regularly, and when I have had (rather minor) problems, the developer has been very responsive.

KRK ROKIT 6 Studio Monitors

I’ve been a recording engineer for a long time. I’ve used Yamaha NS-10s for many years and Meyer HD-1s in many studios (which were the first pro self-powered monitors). For my home studio I use the ROKIT 6 Studio Monitors. They are excellent, transparent, self-powered monitors and they give me a sense of pro sound in my home studio. I do all my recording and mixing “in the box” [doing all the sound mixing on a computer, as opposed to "out of the box" -- using a mixing board and traditional equipment] and these monitors allow me to create mixes that often sound superior to mixes done in “real” studios.

Enhanced Bass Hi-Fi Noise-Isolating Earphones

For over 10 years, I have been listening to music with the Westone UM1 In-Ear Monitor, which I originally discovered via Cool Tools way back in 2003. They are wonderful noise-isolating earbuds, but they have a downside — I have to repurchase them every couple of years because the little plastic earbud stem snaps off, and at $100 a pop, this has become a deal-breaker. So after another pair snapped a couple weeks ago, I decided to explore alternatives.

In my experience, earphones are kind of like sunglasses; it doesn’t make sense to spend a lot of money on them, because they are highly likely to get lost or broken. If I were planning to wear earphones exclusively in my apartment, I might look into purchasing a premium over-the-ear pair, but most of the time I wear them while I am commuting on public transit, jogging, or at the gym — all activities which carry a high potential for impact. They routinely get tugged out or jammed into a pants pocket or bag.

I’ve ordered numerous audio cables from Monoprice over the years with great results, so after reading a few positive reviews online, I decided to give their Enhanced Bass Hi-Fi Noise Isolating Earphones a try. They were cheap (<$8), so it wasn't a big risk. Also, it seems to me that the largest determining factor in headphone sound quality is noise isolation, so I decided to upgrade the stock tips with Comply T-400 Isolation Earphone Tips ($15 Amazon). I’ve been listening to music through this setup for a couple weeks, and although the Monoprice earbuds don’t sound as good as the Westones — the treble can be a little harsh at times — the sound quality is probably 80%. Also, the Comply tips provide a tight, comfortable fit when I’m active. A tip: the cables are wrapped in some sort of fabric which makes them a little rigid, so they can spring out from behind your ears. To solve this problem, I positioned the cables and then tied a knot under my chin, which keeps them in place.

I also purchased a pair of the Monoprice over-the-ear DJ-style headphones ($32 Amazon, $23 Monoprice). These have become my go-to pair; I’ve been wearing them every morning during my SF Muni commute. The consensus of the reviewers on the Monoprice site suggests that the DJ-style headphones are more durable than the lightweight model, and although I wasn’t able to directly compare the two, I will say that they are solidly constructed and the sound quality is great – a deep, rich bass. I’m sure they aren’t on par with a pair of premium over-the-ear headphones, but at 1/10 the price, they are close enough for me.

Bose SoundLink

I’m a roadie who gets to visit “home” on the weekends. My fairly new Bose SoundLink, though, let’s me turn any hotel room into a thoroughly music-infused space. That helps a lot…

This thing has both Bluetooth and a 3.5mm stereo jack on the back. It’s pretty small, has a good battery and a wall-wart transformer (the package I got from Costco also has a cigarette-lighter cord).

It’s not a lightweight little thing and it really packs a punch. It’s really easy to have it (way) too loud in a hotel room. Try that, Jambox.

I plug in my Sansa Clip. Or I play stuff off my phone. Or it plays audio from my tablet, or “replaces” the crappy speakers on my laptop. The sound is surprisingly good at every volume level, and as I said, it can get really loud if you want it to be.

And it’s no trick to operate, it’s very easy to set up.

(Now if I can just find a player that takes microSDXC cards and had Bluetooth too!)

For me, this SoundLink replaces something major from home that I’ve been missing.

Electronic Wind Instrument

As an amateur musician living in a small house, I can’t always pick up my saxophone or flute when I have the urge to make music. Nighttime is off limits, and even during the day I can’t always find a time when I won’t be disturbing the rest of the household. We have a digital piano that I can use with headphones or a computer, but as a wind player I find the keyboard too limiting.

About three years ago, I solved this problem by buying an Akai EWI USB electronic wind instrument. It lets me play quietly, or even silently, while providing more ways to make music than would be practical with real instruments. You hold it like a clarinet or saxophone, touching key pads placed in a similar arrangement to the keys of a real instrument, and blow into a mouthpiece that senses the pressure of your breath. It produces no sound of its own. Instead, you plug it into a computer and choose from dozens of wind, brass, and string instruments to mimic. Add a pair of headphones, and you have a self-contained music studio you can use any time of day or night. You can practice tunes and scales, play along with recordings, and even create your own compositions and arrangements using multiple instruments.

The instrument selection provided by the Akai software includes a full range of woodwinds, brass, and orchestral strings, along with some pitched percussion (like xylophone and glockenspiel) and an assortment of unique synthesizer sounds. The selection includes all the sizes of saxophones, clarinets, brass, double reeds, flutes, and viols. Part of the fun of the EWI is getting to play instruments that you’ve never touched in real life. For instance, I spend a lot of time using the violin sound, and noodling around on bass clarinet or tuba is a blast. The instrument sounds are quite good. The ability to control the volume with your breath adds a natural expressiveness that makes up for the synthetic timbre of some of the instruments. A casual listener might not realize she is hearing an electronic instrument, particularly the clarinets and violin/cello/bass voices.

The EWI’s controls strike a balance between simplicity and realism. Unlike a real instrument, it’s “keys” don’t move. Instead, they are raised metal pads that sense when you are touching them. The layout of the keys closely matches that of a saxophone, though you can configure it to use fingerings that are more similar to a flute, oboe, or even a trumpet. You control the octave using a set of four rollers under your left thumb that give the EWI a five-octave range. Another pair of sensors allows you to bend notes up or down with your left thumb. The mouthpiece, in addition to sensing your breath, also senses the pressure of your bite, providing a way to add vibrato to your tone.

The lack of moving parts makes it extremely reliable, but to your fingers it’s more like playing a keyless instrument like a recorder than a saxophone. It doesn’t take long to get used to once you’ve chosen a fingering configuration.

The real power of the EWI USB and the Akai software comes when you combine them with a music application like GarageBand. The Akai software can act as a plug-in to Garage Band and other software. You can record multiple tracks using different instrument voices. This has greatly expanded my musical capabilities, and I’m now experimenting with creating my own band arrangements.

The EWI USB is not without its flaws. While I’ve had no problems with the Akai software on Macintosh, I’ve seen some pretty severe complaints from Windows users. Users have posted their workarounds and solutions for the Windows problems on the web, but Windows users might want to buy from a retailer with a good reputation for support (like Patchman music). Though it’s a MIDI instrument, it doesn’t have a MIDI port; you have to plug it into a computer. Akai’s documentation is a bit sparse, and doesn’t provide much information on how to use the EWI with other software. While, in principle, the EWI can be used to control any software that accepts MIDI input, I’ve had only limited success with Garage Band’s own (non-Akai) instrument voices. This has more to do with Garage Band’s limitations than EWI’s, but Akai could have done a better job explaining what you can and can’t do with the EWI’s many configuration options. Another problem is that some of the instrument voices sound a bit artificial. Even with breath control, the EWI can’t mimic the variety of sounds that a good player gets out of a real saxophone or trumpet. I’ve found that using Garage Band’s matrix reverb filter (which models the acoustics of real rooms) does a lot to increase the realism of the EWI sounds.

Akai makes a somewhat more advanced version, the EWI4000S, that has a MIDI port and its own built-in sound generator. This might be a better option than the EWI USB if you want to use it in a live performance. Yamaha also makes an advanced wind controller that has moving keys and a mouthpiece that can more closely mimic reed instruments. Both these options are at least twice as expensive as the EWI USB, and may require additional hardware and software instrument “patches” (instrument voices) to match those provided with the EWI USB.

The Akai EWI USB comes with a mouthpiece cap, neck strap, USB cable, and software for Macintosh and Windows computers.

Trupulse Bluetooth Transducer Speaker

I received a TruPulse Bluetooth Transducer Speaker for Christmas, and have been blown away by the portability and sound quality. This little device connects to a sound source via BlueTooth or the included line-in cable, and turns any surface into a speaker through transduction. Tables, boxes, walls – anything you can set it on.

This technology has been around for a while, finding a home in outdoor audio. What makes the TruPulse a Cool Tool is that it’s so portable. I can toss this in the bag with my phone and it’s less cumbersome than a set of speakers. I can pair it with my laptop on the dresser, and set the speaker on my nightstand to have the audio closer to me. It also gets loud enough to serve your livingroom from the coffee table.

I could see this being handy for the laptop road warrior in presentations, since you might have access to a projector, but speakers may be hard to come by.

C. Crane FM Transmitter II

The C. Crane FM Transmitter II takes a signal from an audio source such as an iPod, CD player or computer, and broadcasts it in FM, where it can be picked up by any FM radio within its range of up to 100-feet.

That simple description belies its versatility. I use it as a poor man’s Sonos: I broadcast music and podcasts from my computer to any radio in the house. I am not limited in the devices I use to hear the broadcast; I use a few Boston Acoustics Solo tabletop radios, but any radio would work, even a walkman-type device. Setup is fool-proof; just tune the radio to the proper frequency. Other people use it to watch movies without disturbing other people in the room. They just use an FM radio like the one in many iPods, and earbuds. Musicians use them for stage performance. Etc.

But there are other FM transmitters. This one stands out in a few ways. It has excellent audio quality, as good as you can get with FM. That is especially apparent in the bass frequencies. The limiting factor for your sound will almost certainly be your receiving radio or earbuds.

You can choose any broadcast frequency from 88.3 to 107.7 MHz, so are nearly guaranteed to find a clear frequency for your location. (The “digital” in the name refers to the digital display of the transmitting frequency, nothing else).

It has adjustable gain, so it will amplify even weak signals to the maximum it can handle (an LED indicator tells you when you are overloading it). It runs off AA batteries or its own wall transformer.

It can be very easily modified (by opening the case and turning a little knob) to increase its power dramatically. You can easily find instructions on the web. This is strongly recommended; the only critical reviews are from people who were disappointed with is range out of the box. That is caused by FCC regulations that limit the power allowed in all such devices. The modification will violate those regulations of course, but drastically increase the transmitter’s range.

It is cheap. Truly comparable transmitters cost a few hundred dollars. The version II is cheaper and has better audio quality than the original. And C. Crane occasionally has one that has been returned for even less.

There is basically nothing wrong with this device, and there is nothing better for the price.
