Best Bluetooth Speakers Under 10000 in May 2021 - Save Upto 40%

Wireless Bluetooth speakers are small loudspeakers which get sound signals via radio frequency waves and not via audio cords. These can be placed almost anywhere, since they do not need wires or dongles. The signal travels in the air from a transmitter on the top to the receiver on the bottom.

A good quality Bluetooth speaker must have a range of at least 60 feet so that you can communicate with others in the room. The range will depend on the application. If you want to use these for your television, stereo headphones or for a personal computer (pads), you will need a high range. If you want to connect your iPod to your home stereo system, you need a low band. In some cases you may need a channel number (for speaker output) or a bit rate.

A Bluetooth speaker is used in combination with a home sound system like a jBL quadra or a Bluetooth qosmioite. They provide excellent sound quality even at a substantial distance. They are designed especially to handle sound that has higher frequency. These devices work well when driving. You should only operate them in well ventilated areas.

For all these reasons, I did a full review on the JBL Qosmioite plus Bluetooth speaker. I did this after purchasing and using one for a week. This portable and convenient wireless speaker comes with a five year warranty. The speaker itself however, lasted longer than I expected.

The JBL Qosmioite plus Bluetooth speaker is ideal for anyone who needs a portable and convenient assistant. You can set it up as either a desktop computer or an MP3 player. The Qosmioite offers you the ability to surf the internet as well as play your favorite spotify songs. This makes it extremely convenient to use. It also functions as an mp3 player when the battery is dead, making it a more relaxing choice when you need a spotify companion.

The speakers themselves are not of very high quality. Their build quality is not comparable to that of a high end device. But if you want to listen to your favorite music through the highest quality system possible, this isn’t it. It certainly doesn’t have the same battery life as the wonderboom 2 though. Battery life is one of the biggest drawbacks of the wonderboom 2 since it relies on its larger battery to make up for its lack of portability. It may be great to have however, if you’re a frequent traveler or someone who wants the best Bluetooth speaker for the money.

The speaker itself however, performed just fine. Its volume levels were just fine, but it lacked in terms of sound quality. It wasn’t bad per se, but it just wasn’t very good. Other people were much happier with the performance of the Bluetooth wireless device they had purchased.

Both devices work well. They just differ in their strengths. If you are looking for a good overall wireless speaker system for either music or videos, you will likely be better off with the wonderboom 2. If you want a Bluetooth speaker with excellent sound quality, and portability, the Bluetooth speakers that come with the HP iPAQ will likely be your best bet.

Perhaps the most important thing to consider when choosing one of these wireless speakers is the sound quality. The sound quality of the ip67 rated models is one of the key selling points of the product. If you are going to be listening to high quality music or video you want something with superb sound. The battery powered speaker models tend to fall short in this area. However, the rugged Bluetooth speakers from RadioShack keep their sound quality high.

In addition to excellent sound quality, you want to be sure you get a wireless device with a long battery life. The battery life on the most portable and collapsible wireless speakers tends to be short. You may find you need to recharge it more often than once a month. Some people like the battery life offered on some of the simpler Bluetooth speakers under 10000, but if you like to listen to music source, you will probably prefer a more robust device.

Extra features are available on many wireless speakers. If you need a disc jockey for your Bluetooth speaker listening experience, you can find such devices in most music sources as well. The echo show 5 feature is especially beneficial to the radio listener. With this feature you get a wide range of musical selections and will not miss any beats when you are listening to your favorite music.

Reform: Form Objects Decoupled From Models In Ruby

Reform

Form objects decoupled from your models.

Reform gives you a form object with validations and nested setup of models. It is completely framework-agnostic and doesn't care about your database.

Although reform can be used in any Ruby framework, it comes with Rails support, works with simple_form and other form gems, allows nesting forms to implement has_one and has_many relationships, can compose a form from multiple objects and gives you coercion.

Full Documentation

Reform is part of the Trailblazer framework. Full documentation is available on the project site.

Reform 2.2

Temporary note: Reform 2.2 does not automatically load Rails files anymore (e.g. ActiveModel::Validations). You need the reform-rails gem, see Installation.

Defining Forms

Forms are defined in separate classes. Often, these classes partially map to a model.

class AlbumForm < Reform::Form
  property :title
  validates :title, presence: true
end

Fields are declared using ::property. Validations work exactly as you know it from Rails or other frameworks. Note that validations no longer go into the model.

The API

Forms have a ridiculously simple API with only a handful of public methods.

  1. #initialize always requires a model that the form represents.
  2. #validate(params) updates the form's fields with the input data (only the form, not the model) and then runs all validations. The return value is the boolean result of the validations.
  3. #errors returns validation messages in a classic ActiveModel style.
  4. #sync writes form data back to the model. This will only use setter methods on the model(s).
  5. #save (optional) will call #save on the model and nested models. Note that this implies a #sync call.
  6. #prepopulate! (optional) will run pre-population hooks to "fill out" your form before rendering.

In addition to the main API, forms expose accessors to the defined properties. This is used for rendering or manual operations.

Setup

In your controller or operation you create a form instance and pass in the models you want to work on.

class AlbumsController
  def new
    @form = AlbumForm.new(Album.new)
  end

This will also work as an editing form with an existing album.

def edit
  @form = AlbumForm.new(Album.find(1))
end

Reform will read property values from the model in setup. In our example, the AlbumForm will call album.title to populate the title field.

Rendering Forms

Your @form is now ready to be rendered, either do it yourself or use something like Rails' #form_for, simple_form or formtastic.

= form_for @form do |f|
  = f.input :title

Nested forms and collections can be easily rendered with fields_for, etc. Note that you no longer pass the model to the form builder, but the Reform instance.

Optionally, you might want to use the #prepopulate! method to pre-populate fields and prepare the form for rendering.

Validation

After form submission, you need to validate the input.

class SongsController
  def create
    @form = SongForm.new(Song.new)

    #=> params: {song: {title: "Rio", length: "366"}}

    if @form.validate(params[:song])

The #validate method first updates the values of the form - the underlying model is still treated as immutuable and remains unchanged. It then runs all validations you provided in the form.

It's the only entry point for updating the form. This is per design, as separating writing and validation doesn't make sense for a form.

This allows rendering the form after validate with the data that has been submitted. However, don't get confused, the model's values are still the old, original values and are only changed after a #save or #sync operation.

Syncing Back

After validation, you have two choices: either call #save and let Reform sort out the rest. Or call #sync, which will write all the properties back to the model. In a nested form, this works recursively, of course.

It's then up to you what to do with the updated models - they're still unsaved.

Saving Forms

The easiest way to save the data is to call #save on the form.

if @form.validate(params[:song])
  @form.save  #=> populates album with incoming data
              #   by calling @form.album.title=.
else
  # handle validation errors.
end

This will sync the data to the model and then call album.save.

Sometimes, you need to do saving manually.

Default values

Reform allows default values to be provided for properties.

class AlbumForm < Reform::Form
  property :price_in_cents, default: 9_95
end

Saving Forms Manually

Calling #save with a block will provide a nested hash of the form's properties and values. This does not call #save on the models and allows you to implement the saving yourself.

The block parameter is a nested hash of the form input.

  @form.save do |hash|
    hash      #=> {title: "Greatest Hits"}
    Album.create(hash)
  end

You can always access the form's model. This is helpful when you were using populators to set up objects when validating.

  @form.save do |hash|
    album = @form.model

    album.update_attributes(hash[:album])
  end

Nesting

Reform provides support for nested objects. Let's say the Album model keeps some associations.

class Album < ActiveRecord::Base
  has_one  :artist
  has_many :songs
end

The implementation details do not really matter here, as long as your album exposes readers and writes like Album#artist and Album#songs, this allows you to define nested forms.

class AlbumForm < Reform::Form
  property :title
  validates :title, presence: true

  property :artist do
    property :full_name
    validates :full_name, presence: true
  end

  collection :songs do
    property :name
  end
end

You can also reuse an existing form from elsewhere using :form.

property :artist, form: ArtistForm

Nested Setup

Reform will wrap defined nested objects in their own forms. This happens automatically when instantiating the form.

album.songs #=> [<Song name:"Run To The Hills">]

form = AlbumForm.new(album)
form.songs[0] #=> <SongForm model: <Song name:"Run To The Hills">>
form.songs[0].name #=> "Run To The Hills"

Nested Rendering

When rendering a nested form you can use the form's readers to access the nested forms.

= text_field :title,         @form.title
= text_field "artist[name]", @form.artist.name

Or use something like #fields_for in a Rails environment.

= form_for @form do |f|
  = f.text_field :title

  = f.fields_for :artist do |a|
    = a.text_field :name

Nested Processing

validate will assign values to the nested forms. sync and save work analogue to the non-nested form, just in a recursive way.

The block form of #save would give you the following data.

@form.save do |nested|
  nested #=> {title:  "Greatest Hits",
         #    artist: {name: "Duran Duran"},
         #    songs: [{title: "Hungry Like The Wolf"},
         #            {title: "Last Chance On The Stairways"}]
         #   }
  end

The manual saving with block is not encouraged. You should rather check the Disposable docs to find out how to implement your manual tweak with the official API.

Populating Forms

Very often, you need to give Reform some information how to create or find nested objects when validateing. This directive is called populator and documented here.

Installation

Add this line to your Gemfile:

gem "reform"

Reform works fine with Rails 3.1-5.0. However, inheritance of validations with ActiveModel::Validations is broken in Rails 3.2 and 4.0.

Since Reform 2.2, you have to add the reform-rails gem to your Gemfile to automatically load ActiveModel/Rails files.

gem "reform-rails"

Since Reform 2.0 you need to specify which validation backend you want to use (unless you're in a Rails environment where ActiveModel will be used).

To use ActiveModel (not recommended because very out-dated).

require "reform/form/active_model/validations"
Reform::Form.class_eval do
  include Reform::Form::ActiveModel::Validations
end

To use dry-validation (recommended).

require "reform/form/dry"
Reform::Form.class_eval do
  feature Reform::Form::Dry
end

Put this in an initializer or on top of your script.

Compositions

Reform allows to map multiple models to one form. The complete documentation is here, however, this is how it works.

class AlbumForm < Reform::Form
  include Composition

  property :id,    on: :album
  property :title, on: :album
  property :songs, on: :cd
  property :cd_id, on: :cd, from: :id
end

When initializing a composition, you have to pass a hash that contains the composees.

AlbumForm.new(album: album, cd: CD.find(1))

More

Reform comes many more optional features, like hash fields, coercion, virtual fields, and so on. Check the full documentation here.

Reform is part of the Trailblazer project. Please buy my book to support the development and learn everything about Reform - there's two chapters dedicated to Reform!

Security And Strong_parameters

By explicitly defining the form layout using ::property there is no more need for protecting from unwanted input. strong_parameter or attr_accessible become obsolete. Reform will simply ignore undefined incoming parameters.

This is not Reform 1.x!

Temporary note: This is the README and API for Reform 2. On the public API, only a few tiny things have changed. Here are the Reform 1.2 docs.

Anyway, please upgrade and report problems and do not simply assume that we will magically find out what needs to get fixed. When in trouble, join us on Gitter.

Full documentation for Reform is available online, or support us and grab the Trailblazer book. There is an Upgrading Guide to help you migrate through versions.

Bluetooth Bug Opens Devices to Man-in-the-Middle Attacks

A high-severity Bluetooth vulnerability has been uncovered, which could enable an unauthenticated attacker within wireless range to eavesdrop or alter communications between paired devices.

The flaw (CVE-2020-15802), discovered independently by researchers at the École Polytechnique Fédérale de Lausanne (EPFL) and Purdue University, is being referred to as “BLURtooth.” The issue exists in the pairing process for Bluetooth 4.0 through 5.0 implementations. This pairing process is called Cross-Transport Key Derivation (CTKD).

“Devices… using [CTKD] for pairing are vulnerable to key overwrite, which enables an attacker to gain additional access to profiles or services that are not restricted, by reducing the encryption key strength or overwriting an authenticated key with an unauthenticated key,” according to a security advisory on Wednesday by the Carnegie Mellon CERT Coordination Center.
