Take command of your MIDI music gear with the BOSS EV-1-WL, the world’s first wireless MIDI expression pedal. The EV-1-WL provides wireless foot control for BOSS products such as the EURUS GS-1, Waza-Air, and Katana-Air music apps on mobile devices, and anything that can receive CC messages via Bluetooth® MIDI. In addition, USB and MIDI TRS connectivity are on hand for wired control of computer music software and standard MIDI devices. Whether you go wireless or wired—or both at once—the EV-1-WL delivers a ton of MIDI power in a compact footprint.Expand Your Performance Range with Bluetooth
The EV-1-WL is the ideal creative partner for the growing range of music performance hardware with Bluetooth wireless support. Use it to control pitch bend, filter, and other synth functions in the BOSS EURUS GS-1 guitar. Or add external footswitches to create a mini Bluetooth pedalboard for patch selection, wah/volume control, and more in the Waza-Air and Katana-Air wireless guitar amp systems. The EV-1-WL can also communicate wirelessly with a standard 5-pin MIDI device that has the Roland WM-1 Wireless MIDI Adaptor installed.
Wireless MIDI Control for Computers and Mobile Devices
Pair the EV-1-WL via Bluetooth with Mac computers, smartphones, and tablets to interface with music apps that support remote operation with MIDI CC messages, from guitar amp simulators and effects to virtual instruments and music production software. And if you’re a Windows user, you can add a Roland WM-1D dongle for wireless communication with the EV-1-WL.
Plug-and-Play via USB
The EV-1-WL also works as a standalone USB MIDI controller for music software on Mac or Windows computers. The class-compliant interface means there are no drivers to install—simply plug in with a USB cable and configure your software as needed for external MIDI input.
Control MIDI Stompboxes, Multi-Effects, and More
With its space-saving TRS MIDI output, the EV-1-WL is a powerful accessory for all types of MIDI music hardware, from effect pedals and multi-effects processors to keyboards, drum machines, and beyond. Use a TRS-to-TRS cable with mini plugs to connect with BOSS pedals equipped with TRS MIDI, including 200 series effects and the RC-5 and RC-500 Loop Stations. Or grab the BOSS BMIDI-5-35 cable to connect with any device that has a standard 5-pin MIDI input jack.
Deep Customization
The free EV-1-WL Editor app for iOS and Android devices lets you customize MIDI CC assignments for the EV-1-WL’s pedal, toe switch, and up to two external footswitches. The Bluetooth, USB, and TRS MIDI outputs support simultaneous operation, and you can create independent control settings for each. It’s also possible to set the switches for momentary or latching operation, adjust the pedal’s response curve, and more.

It froths, but is not dependent
Color: C-Black, Size: Model C Rechargeable
While this frother does “froth”, it has many more cons than pros. The ONLY pro is it froths. The cons—only good for a traditional coffee cup. It is not water proof, and the instructions say to keep the “unit “ dry. As you froth, the liquid naturally raises height. If you are trying to use a Togo coffee mug, or thermos type travel mug—it only works well if done it three or four levels to ensure keeping the motor above the liquid. The “rechargeable “ function DOES recharge, however- it may last 1use or a few. It’s VERY inconsistent. And does not seem to be related to how long you allow it to charge. Overall—not a good buy. I had mine maybe 3 months before it quit working. And at 2 months it started becoming spastic. Even after just being charged-it wouldn’t even froth 1cup. AVOID!!

Easy to Use and Works Great
Color: C-Black, Size: Model C Rechargeable, Color: C-Black, Size: Model C Rechargeable
This milk frother works amazingly well! It’s powerful, easy to use, and creates rich, creamy foam in just seconds. The rechargeable design is very convenient, and the battery lasts a long time between charges. It feels sturdy and well-made, and cleaning it is quick and simple. I use it every day for my coffee, lattes, and hot chocolate, and it has exceeded my expectations. If you’re looking for an affordable and effective milk frother, this is definitely a great choice. Highly recommended

Love it!
Color: C-Black, Size: Model C Rechargeable
Love mine! No more batteries. I make at least two cups a day and froth my creamer. Love the fact I don’t have to recharge very often.

Works way better than its price would suggest
Color: Storage Cover Black, Size: Rechargeable
A family member got frothed milk in their coffee and loved it, so they started doing it at home. They were using a wand mixer which is great at splashing milk all over creation but not very good at actually frothing it.
I asked them what kind of frother they wanted and they gave me 2 criteria: Rechargeable, and inexpensive. They didn't want to spend a lot on something they might not like or might outgrow, and they didn't want to constantly be looking for batteries.
This frother fits the bill. It recharges with a regular USB-C cable and comes with a short one (but not a wall plug so make sure you have one of those). It was also less than $11 delivered so not a lot to gamble on an occasional-use gadget.
Does it work? Absolutely, and a lot better than I ever thought it would. I was given a demonstration and in 10 seconds I saw a small cup of half and half turn into frothy foam. I'll admit, it does taste pretty good in coffee.
I 3D printed a stand to hold the mixer upright on the counter. Otherwise the base is too small and it tips over. That's not a complaint, just an observation. If you want it to stand upright, you'll have to do something similar. Otherwise, this thing is a good combination of simple, inexpensive, and effective.
